Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:00:06,250 --> 00:00:11,400
Victim is Mr Arnie Rahul.
Consultant surgeon. 48 years of age.
2
00:00:11,500 --> 00:00:14,200
Good reputation, though he's fallen
out with a few people recently.
3
00:00:14,201 --> 00:00:16,301
He was about to start an operation.
He gets a phone call.
4
00:00:16,320 --> 00:00:18,820
Walks out, never comes back.
5
00:00:19,520 --> 00:00:22,040
Single puncture wound to
the left chest wall.
6
00:00:23,240 --> 00:00:26,040
What's that in his hand?
Looks like a syringe and needle.
7
00:00:26,040 --> 00:00:29,280
It's a Hickman line.
A long-term vascular access device
8
00:00:29,280 --> 00:00:31,800
for people who need chemotherapy
or blood transfusions.
9
00:00:31,800 --> 00:00:34,520
The assailant would have had
extensive cross contamination
10
00:00:34,520 --> 00:00:36,000
with the victim's blood.
11
00:00:36,000 --> 00:00:38,160
Stick that in to a big artery
and blood will flow out
12
00:00:38,160 --> 00:00:39,720
like a high-pressure hose.
13
00:00:39,720 --> 00:00:41,080
Simi Jacobs.
14
00:00:42,160 --> 00:00:43,520
He's denying everything.
15
00:00:44,600 --> 00:00:47,840
Simi Jacobs is not a match
16
00:00:47,840 --> 00:00:49,480
to the blood spatter at the scene.
17
00:00:49,480 --> 00:00:51,760
So, who is it? It's Wilfred Okoye.
18
00:00:51,760 --> 00:00:52,880
The patient?
19
00:00:52,880 --> 00:00:56,640
Arnie Rahul was murdered by a man
who was under general anaesthetic
20
00:00:56,640 --> 00:00:58,040
in a different room?
21
00:00:58,040 --> 00:01:01,680
Blood alcohol level, three times
the legal driving limit.
22
00:01:01,680 --> 00:01:04,000
You said he shouldn't be operating.
23
00:01:04,000 --> 00:01:06,000
Not after the Harry Fletcher
incident.
24
00:01:06,000 --> 00:01:08,920
Arrested on the table
during surgery last week.
25
00:01:08,920 --> 00:01:11,560
I want you to do the postmortem.
26
00:01:11,560 --> 00:01:13,760
Technically that would be
a conflict of interest.
27
00:01:13,760 --> 00:01:17,040
Summarising postmortem examination,
Harry Fletcher.
28
00:01:17,040 --> 00:01:18,960
What are you doing?
My colleagues are here.
29
00:01:18,960 --> 00:01:21,920
Is that Emily Braithwaite?
She's Adam's godmother.
30
00:01:21,920 --> 00:01:24,040
You'd think he might have
mentioned it.
31
00:01:24,040 --> 00:01:26,560
Are you going to confront him?
Not yet.
32
00:01:26,560 --> 00:01:29,000
Your original stem cell work
was brilliant.
33
00:01:29,000 --> 00:01:32,880
But you tried and failed to turn
it into a viable cancer treatment.
34
00:01:32,880 --> 00:01:35,440
Wilfred Okoye, still in
the hospital.
35
00:01:35,440 --> 00:01:37,120
What's he going to know?
36
00:01:37,120 --> 00:01:40,080
You won't find out unless you
ask him.
37
00:01:40,080 --> 00:01:42,960
Mr Fletcher died because of
surgical error.
38
00:01:42,960 --> 00:01:46,520
Adam! You have no idea what
you've done.
39
00:01:46,520 --> 00:01:49,040
When I applied for this job
I falsified my CV,
40
00:01:49,040 --> 00:01:50,920
and Emily Braithwaite tried to
use this
41
00:01:50,920 --> 00:01:53,200
fact to influence my findings in
the Fletcher Case.
42
00:01:53,200 --> 00:01:54,880
Here's my letter of resignation.
43
00:01:54,880 --> 00:01:56,160
Effective immediately.
44
00:01:57,680 --> 00:02:03,720
Testator silens
45
00:02:06,240 --> 00:02:13,400
Costestes e spiritu
46
00:02:13,400 --> 00:02:20,880
Silencium
47
00:02:28,200 --> 00:02:34,000
Testator silens.
48
00:02:40,120 --> 00:02:42,720
DISTANT SIREN
49
00:02:45,520 --> 00:02:49,080
Wilfred Okoye, a Beninese
farm worker, was admitted
50
00:02:49,080 --> 00:02:53,240
to St Jude's hospital for the
treatment of leukaemia a week ago.
51
00:02:53,240 --> 00:02:56,640
Although he lost consciousness
briefly during the attack
52
00:02:56,640 --> 00:03:00,320
on his life last night, he seems to
have recovered with no ill effects.
53
00:03:00,320 --> 00:03:04,640
Awaiting toxicology from the syringe
we believe was used in the attack.
54
00:03:04,640 --> 00:03:06,400
Prints? Fibres?
55
00:03:06,400 --> 00:03:08,680
Nothing conclusive.
We're interviewing witnesses
56
00:03:08,680 --> 00:03:10,840
but no-one got a good look at
the attacker.
57
00:03:10,840 --> 00:03:13,360
How come he's being treated here
in the UK?
58
00:03:13,360 --> 00:03:17,200
It was set up by a charity,
and then arranged through Rahul.
59
00:03:18,800 --> 00:03:23,040
Here is a man who has lived his
entire life in Benin
60
00:03:23,040 --> 00:03:27,240
up until a week ago, and,
according to our DNA evidence,
61
00:03:27,240 --> 00:03:31,520
murders his surgeon while under
anaesthetic in a different room.
62
00:03:35,120 --> 00:03:40,720
Could the DNA at the murder scene
been a contaminant or planted?
63
00:03:40,720 --> 00:03:43,480
No. The spatter patterns are
too perfect.
64
00:03:43,480 --> 00:03:45,840
It came from someone who
was in the room at the time.
65
00:03:45,840 --> 00:03:47,480
So, how do you explain it?
66
00:03:50,800 --> 00:03:53,880
How do we know Wilfred
was anaesthetised?
67
00:03:53,880 --> 00:03:56,680
I mean, how do we know it was him?
68
00:03:56,680 --> 00:03:58,320
What, he's got an identical twin?
69
00:03:58,320 --> 00:03:59,800
Bit fantastical, Steve.
70
00:03:59,800 --> 00:04:01,640
I don't know.
71
00:04:01,640 --> 00:04:03,240
There's another explanation.
72
00:04:05,320 --> 00:04:07,440
DNA samples got mixed up.
73
00:04:07,440 --> 00:04:09,440
Ah! No way!
74
00:04:09,440 --> 00:04:12,640
Look, I'm just putting it out there.
Mm-mn. We could run the test again.
75
00:04:12,640 --> 00:04:14,640
Those samples were
handled correctly.
76
00:04:16,080 --> 00:04:18,280
Jack, shall we just run them again?
77
00:04:21,560 --> 00:04:23,320
Right, yep. Good.
78
00:04:24,560 --> 00:04:25,600
OK.
79
00:04:26,720 --> 00:04:28,720
Let me know when toxicology
comes back.
80
00:04:37,040 --> 00:04:40,520
So, the samples got mixed up,
did they? It's always possible.
81
00:04:40,520 --> 00:04:41,560
Mm-hm.
82
00:04:42,560 --> 00:04:45,800
You know who took the swab from
Simi Jacobs. Adam.
83
00:04:47,240 --> 00:04:48,560
What are you suggesting?
84
00:04:50,600 --> 00:04:52,080
Just saying.
85
00:04:58,560 --> 00:05:00,840
PHONE RINGS
86
00:05:00,840 --> 00:05:02,640
VOICEMAIL: You have reached
Dr Adam Yuen.
87
00:05:02,640 --> 00:05:04,240
I am unable to take your call.
88
00:05:04,240 --> 00:05:06,200
Please leave a message
after the tone.
89
00:05:09,000 --> 00:05:11,560
Do you know what I don't understand?
90
00:05:11,560 --> 00:05:13,760
It was just a six-month placement,
91
00:05:13,760 --> 00:05:16,400
and his CV is impressive
enough without it.
92
00:05:16,400 --> 00:05:19,560
So, why did he risk his career
and lie about it?
93
00:05:22,520 --> 00:05:24,840
Has he lied about anything else?
94
00:05:24,840 --> 00:05:27,360
Everything else checks out.
95
00:05:27,360 --> 00:05:28,840
Are you sure about that?
96
00:05:32,280 --> 00:05:35,960
You have an injury over your
left eye and a wound on your neck.
97
00:05:37,440 --> 00:05:39,400
How do you account for them, Simi?
98
00:05:40,640 --> 00:05:42,120
Yeah, I got mugged.
99
00:05:42,120 --> 00:05:44,560
A kid with a knife. Really?
100
00:05:46,320 --> 00:05:48,600
And did you report the assault?
101
00:05:48,600 --> 00:05:51,160
No. Why not?
102
00:05:51,160 --> 00:05:52,760
What, are you going to catch him?
103
00:05:54,920 --> 00:05:58,240
He's answered your questions,
so unless you have other evidence?
104
00:06:11,680 --> 00:06:13,520
PHONE PINGS
105
00:06:21,480 --> 00:06:24,880
Tox results from the syringe
used in the attack on Wilfred.
106
00:06:24,880 --> 00:06:26,640
Here we go. Let's have a look.
107
00:06:31,760 --> 00:06:33,960
That's it? Midazolam?
108
00:06:36,200 --> 00:06:38,400
That's a sedative, isn't it?
109
00:06:38,400 --> 00:06:39,440
Yeah.
110
00:06:41,600 --> 00:06:45,680
The full syringe would have had
about five milligrams in it.
111
00:06:45,680 --> 00:06:46,800
That's not very much.
112
00:06:47,840 --> 00:06:51,920
So, either the assailant
is incompetent,
113
00:06:51,920 --> 00:06:54,200
or this wasn't intended to kill him.
114
00:06:55,720 --> 00:06:58,600
So, what's the aim?
115
00:06:58,600 --> 00:07:00,240
Kidnapping?
116
00:07:03,000 --> 00:07:05,080
HE SIGHS
117
00:07:05,080 --> 00:07:07,200
The guy's already ill.
118
00:07:07,200 --> 00:07:09,520
You know...
119
00:07:09,520 --> 00:07:13,480
If someone wanted him dead, it's not
going to be that hard, is it?
120
00:07:13,480 --> 00:07:14,800
He's got leukaemia.
121
00:07:16,640 --> 00:07:19,400
It would look like natural causes
if he died of sepsis.
122
00:07:21,960 --> 00:07:24,960
Should I get that syringe tested
again for bacteria?
123
00:07:31,720 --> 00:07:34,320
What's this about Mr Okoye
being moved?
124
00:07:34,320 --> 00:07:35,760
It's for his own safety.
125
00:07:35,760 --> 00:07:38,440
To the Cowley Institute?
And who's paying for that?
126
00:07:38,440 --> 00:07:41,400
Oh, I've been assured that they have
all the facilities required,
127
00:07:41,400 --> 00:07:44,160
and they've offered to do
the treatment free of charge.
128
00:07:44,160 --> 00:07:45,560
I will not allow it.
129
00:07:45,560 --> 00:07:48,800
Someone in your hospital is trying
to kill Mr Okoye.
130
00:07:50,320 --> 00:07:53,480
Quite frankly, Dr Braithwaite,
I don't need your permission.
131
00:08:06,080 --> 00:08:07,360
Haematology lab.
132
00:08:08,760 --> 00:08:10,760
Dr Braithwaite here.
133
00:08:10,760 --> 00:08:15,560
Wilfred Okoye, hospital number
1187266.
134
00:08:15,560 --> 00:08:18,080
I want all his stored blood
and marrow samples sent
135
00:08:18,080 --> 00:08:19,720
to my office immediately.
136
00:08:46,880 --> 00:08:49,000
Finished!
137
00:08:49,000 --> 00:08:53,760
79 needles swabbed and ready to go.
138
00:08:55,320 --> 00:08:57,680
You've got to see this.
139
00:08:57,680 --> 00:08:59,680
Microbiology results from
the syringe
140
00:08:59,680 --> 00:09:01,920
used in the attack on Wilfred.
141
00:09:01,920 --> 00:09:05,160
Turns out it is full of bacteria -
E coli.
142
00:09:06,920 --> 00:09:09,080
Well, it was lying around on
the floor.
143
00:09:09,080 --> 00:09:10,360
Could it be a contaminant?
144
00:09:10,360 --> 00:09:13,040
No. It's a pure growth -
just one type of bug in there.
145
00:09:13,040 --> 00:09:14,920
If it was a contaminant
you'd expect to see
146
00:09:14,920 --> 00:09:16,680
lots of different organisms.
147
00:09:16,680 --> 00:09:18,320
It's been created deliberately.
148
00:09:19,560 --> 00:09:23,320
So, what? The killer sneaks into
Wilfred's room pretending
149
00:09:23,320 --> 00:09:26,880
to be a nurse, inoculates him with
the bacteria,
150
00:09:26,880 --> 00:09:28,240
but adds a mild sedative...
151
00:09:30,440 --> 00:09:33,280
..so that when the real nurse comes
in with his medication,
152
00:09:33,280 --> 00:09:36,880
he's asleep and can't tell her that
someone else has already been in.
153
00:09:38,080 --> 00:09:39,800
He gets sepsis, he dies.
154
00:09:39,800 --> 00:09:41,280
Looks like natural causes.
155
00:09:42,840 --> 00:09:44,560
I need to tell DI Cracknell.
156
00:09:44,560 --> 00:09:47,160
You need to tell the doctors
looking after Wilfred.
157
00:09:51,320 --> 00:09:55,520
HEART MONITOR BEEPS
158
00:09:56,760 --> 00:09:58,960
HE BREATHES RAPIDLY
159
00:10:01,560 --> 00:10:04,200
ALARM SOUNDS
160
00:10:09,640 --> 00:10:11,520
HEART MONITOR BEEPS RAPIDLY
161
00:10:14,840 --> 00:10:16,960
HEART MONITOR FLATLINES
162
00:10:40,440 --> 00:10:43,360
It's as we expected - extensive
peripheral oedema,
163
00:10:43,360 --> 00:10:46,680
multiple organ failure,
consistent with sepsis.
164
00:10:46,680 --> 00:10:50,680
Yep. Toxicology shows only
medications used for his treatment,
165
00:10:50,680 --> 00:10:54,160
antibiotics, ceftriaxone,
gentamicin present
166
00:10:54,160 --> 00:10:55,880
in therapeutic concentrations.
167
00:10:55,880 --> 00:10:59,240
So, cause of death is consistent
with deliberate inoculation
168
00:10:59,240 --> 00:11:02,120
of the culture of E coli,
on a background
169
00:11:02,120 --> 00:11:05,520
of chemotherapy-induced
immune compromise.
170
00:11:05,520 --> 00:11:08,640
Well, we've got no other
leads on his attacker at present.
171
00:11:08,640 --> 00:11:11,040
We're liaising with
the Beninese Consulate to inform
172
00:11:11,040 --> 00:11:13,640
the family of the deceased.
173
00:11:13,640 --> 00:11:19,000
DNA says Wilfred Okoye was guilty of
Rahul's murder,
174
00:11:19,000 --> 00:11:21,360
but being unconscious,
had the perfect alibi.
175
00:11:23,040 --> 00:11:26,040
When a murder suspect gets murdered,
what does that mean?
176
00:11:26,040 --> 00:11:27,760
Framed by the real murderer?
177
00:11:27,760 --> 00:11:30,360
Why would you frame someone with
the perfect alibi?
178
00:11:36,560 --> 00:11:38,760
Simi Jacobs.
179
00:11:38,760 --> 00:11:40,440
What's his home address?
180
00:11:40,440 --> 00:11:41,480
Erm...
181
00:11:43,320 --> 00:11:47,080
Let's see. Flat 32, Bardwell House,
Lincoln Street.
182
00:11:47,080 --> 00:11:50,720
Thought so. Okoye and Jacobs have
been living together.
183
00:11:50,720 --> 00:11:53,920
Simi Jacobs has already been
released, guv.
184
00:11:53,920 --> 00:11:56,520
What? Yeah. Lack of forensics.
185
00:11:56,520 --> 00:11:58,000
All right.
186
00:11:58,000 --> 00:12:00,000
Might I suggest we pick
him up again?
187
00:12:07,160 --> 00:12:09,240
It still doesn't get us anywhere.
188
00:12:09,240 --> 00:12:11,000
It doesn't explain the DNA.
189
00:12:11,000 --> 00:12:13,400
And Simi was in custody
when Wilfred was attacked,
190
00:12:13,400 --> 00:12:14,800
so it doesn't even explain that.
191
00:12:14,800 --> 00:12:17,280
We're just going round in
circles. Yep.
192
00:12:28,160 --> 00:12:31,320
When he was interviewed,
Wilfred said his leukaemia
193
00:12:31,320 --> 00:12:34,000
was common in his region.
194
00:12:36,640 --> 00:12:38,000
Doesn't sound right to me.
195
00:12:52,960 --> 00:12:54,840
PHONE RINGS
196
00:12:54,840 --> 00:12:56,880
VOICEMAIL: You have reached
Dr Adam Yuen.
197
00:12:56,880 --> 00:12:58,320
I am unable to take your call.
198
00:12:58,320 --> 00:13:00,280
Please leave a message
after the tone.
199
00:13:03,200 --> 00:13:05,160
Wait there. He's not in, guv.
200
00:13:05,160 --> 00:13:06,840
And the neighbours haven't seen him.
201
00:13:06,840 --> 00:13:09,120
He's not been seen back at work
at the hospital either.
202
00:13:09,120 --> 00:13:12,000
You two stick around in case
he comes back.
203
00:13:12,000 --> 00:13:15,240
I'm sorry, guv. I should
have spotted the address.
204
00:13:17,040 --> 00:13:19,000
Don't worry about it.
205
00:13:19,000 --> 00:13:22,160
At least you didn't wrongly arrest
a bereaved cancer patient.
206
00:13:26,520 --> 00:13:28,040
I'll do that next time.
207
00:13:32,360 --> 00:13:33,400
Bye.
208
00:13:38,360 --> 00:13:40,600
Nine missed calls.
You're very persistent.
209
00:13:43,600 --> 00:13:45,240
I didn't want to end it like that.
210
00:13:47,880 --> 00:13:49,560
Can I help?
211
00:14:00,560 --> 00:14:03,600
You should have told me that
Emily Braithwaite is your godmother.
212
00:14:03,600 --> 00:14:05,520
Some godmother.
213
00:14:05,520 --> 00:14:08,120
No doubt you've received
the incriminating evidence about me.
214
00:14:08,120 --> 00:14:09,320
What evidence?
215
00:14:10,960 --> 00:14:13,720
She never sent it.
I should have guessed.
216
00:14:13,720 --> 00:14:16,880
If she tried to blackmail you,
then we'll make her answer for that.
217
00:14:16,880 --> 00:14:18,000
She's far too clever.
218
00:14:19,960 --> 00:14:22,880
Why do I think there's more to this
than you're telling me?
219
00:14:24,600 --> 00:14:26,840
No, I just lied to advance
my career.
220
00:14:26,840 --> 00:14:29,880
Really? Just to say you had a
fellowship. Why would you do that?
221
00:14:35,440 --> 00:14:36,960
My family are all doctors.
222
00:14:36,960 --> 00:14:38,960
I was always going to be a surgeon.
223
00:14:38,960 --> 00:14:40,680
It was more or less decided for me.
224
00:14:42,560 --> 00:14:45,680
Final year of medical school,
I was walking to uni
225
00:14:45,680 --> 00:14:48,920
and a cyclist is knocked off her
bike, right in front of me.
226
00:14:48,920 --> 00:14:50,760
Now, I was a keen student.
227
00:14:50,760 --> 00:14:53,840
I used to carry
a first aid kit around with me.
228
00:14:53,840 --> 00:14:57,520
If I'm honest, I was always waiting
for something like this.
229
00:14:57,520 --> 00:15:00,920
When I think about that it's
actually what I'm most ashamed of.
230
00:15:00,920 --> 00:15:03,200
She had facial injuries.
231
00:15:03,200 --> 00:15:05,840
Heavy, laboured breathing.
She was losing consciousness fast.
232
00:15:05,840 --> 00:15:07,760
So, I thought, "She's suffocating.
233
00:15:07,760 --> 00:15:12,120
"She needs a surgical airway,
a cricothyroidotomy."
234
00:15:12,120 --> 00:15:13,480
So, I made my incision.
235
00:15:13,480 --> 00:15:16,000
Something that I had
practised on mannequins.
236
00:15:16,000 --> 00:15:20,160
What I didn't know is that she had
an abnormal anatomy -
237
00:15:20,160 --> 00:15:23,600
an aberrant subclavian artery,
looping high in the neck.
238
00:15:24,760 --> 00:15:28,080
It's present in 1% of people
and 0% of mannequins.
239
00:15:28,080 --> 00:15:30,480
How could you have known?
It was a bloodbath.
240
00:15:38,160 --> 00:15:41,000
The artery retracted back into
her chest.
241
00:15:41,000 --> 00:15:43,600
There was nothing we could do
to save her.
242
00:15:43,600 --> 00:15:45,760
She bled to death in minutes.
243
00:15:50,200 --> 00:15:52,720
My father was furious.
244
00:15:54,400 --> 00:15:57,080
Not because I stupidly tried
a tracheostomy
245
00:15:57,080 --> 00:15:58,840
and killed an innocent young girl.
246
00:16:00,440 --> 00:16:04,240
But because I didn't study hard
enough to do it competently.
247
00:16:06,480 --> 00:16:10,960
So, he used his influence
and arranged for my fellowship
248
00:16:10,960 --> 00:16:12,720
as cover. For what?
249
00:16:16,640 --> 00:16:18,120
For my absence.
250
00:16:21,440 --> 00:16:24,720
It took months of therapy before
I could even leave the house.
251
00:16:33,480 --> 00:16:37,080
The irony in all of this is that
the one who helped me out
252
00:16:37,080 --> 00:16:38,760
the most was Emily Braithwaite.
253
00:16:40,200 --> 00:16:42,800
She visited me more often than
my parents.
254
00:16:45,840 --> 00:16:47,080
She understood.
255
00:16:50,000 --> 00:16:52,320
But there was no way I was going
to be a surgeon.
256
00:16:56,000 --> 00:16:58,640
So, I decided to choose pathology,
257
00:16:58,640 --> 00:17:02,520
and a false narrative was created as
to why I made the switch.
258
00:17:04,200 --> 00:17:07,120
When you start lying,
259
00:17:07,120 --> 00:17:09,400
you have to keep lying.
260
00:17:29,200 --> 00:17:31,240
Jack. Mm? I need to talk to you.
261
00:17:31,240 --> 00:17:32,600
Sure, what's up...?
262
00:17:35,120 --> 00:17:36,520
Hi.
263
00:17:36,520 --> 00:17:37,640
Are you kidding me?
264
00:17:41,000 --> 00:17:43,360
He doesn't work here any more
because he lied to us, do you
265
00:17:43,360 --> 00:17:46,080
remember? Do you remember that?
Adam's got a theory about Wilfred.
266
00:17:46,080 --> 00:17:47,640
Oh, right. Just hear him out.
267
00:17:47,640 --> 00:17:51,640
So, um, I just have to trust
him now?
268
00:17:51,640 --> 00:17:53,640
No, you've got to trust me.
269
00:17:57,520 --> 00:17:58,640
Think about it.
270
00:17:59,960 --> 00:18:02,600
Why would someone want Wilfred dead?
271
00:18:02,600 --> 00:18:04,880
What did he know that was such
a threat that someone
272
00:18:04,880 --> 00:18:05,920
had to kill him?
273
00:18:07,560 --> 00:18:11,000
Wilfred was being treated for acute
myeloid leukaemia.
274
00:18:11,000 --> 00:18:12,240
That's rare.
275
00:18:12,240 --> 00:18:14,760
Remember, he said there were
lots of other cases in his small
276
00:18:14,760 --> 00:18:16,960
village in Africa.
277
00:18:16,960 --> 00:18:19,680
What if Wilfred wasn't killed
because of what he knew?
278
00:18:19,680 --> 00:18:20,840
Don't follow.
279
00:18:20,840 --> 00:18:22,640
Wilfred wasn't the witness.
280
00:18:24,800 --> 00:18:26,120
He was the evidence.
281
00:18:29,600 --> 00:18:32,000
This is a trephine biopsy of
the bone marrow.
282
00:18:32,000 --> 00:18:35,720
We take a thin core of bone
with marrow cells in it.
283
00:18:35,720 --> 00:18:38,040
I've already taken an aspirate of
the fluids.
284
00:18:49,280 --> 00:18:52,760
So, the question is, why would so
many people from one place
285
00:18:52,760 --> 00:18:54,160
all get leukaemia?
286
00:18:55,400 --> 00:18:57,240
And that's going to tell you, is it?
287
00:18:57,240 --> 00:18:59,080
To be honest, I've never done
this before.
288
00:18:59,080 --> 00:19:01,080
Not postmortem, anyway.
289
00:19:01,080 --> 00:19:04,240
But you know what? It's crazy
enough for it to work. Mm-mm.
290
00:19:16,000 --> 00:19:17,040
Thanks.
291
00:19:19,080 --> 00:19:22,440
Oh, look. Here's a billion
DNA results from the needles.
292
00:19:24,040 --> 00:19:27,000
Want to give me a hand going
through these?
293
00:19:27,000 --> 00:19:28,160
Didn't think so.
294
00:19:46,160 --> 00:19:48,840
Nikki? The slide's ready when you
want to have a look.
295
00:19:57,240 --> 00:19:59,880
Good yield of cells.
More than I expected.
296
00:19:59,880 --> 00:20:02,320
Definitely acute myeloid leukaemia.
297
00:20:02,320 --> 00:20:05,800
It's not typical.
Looks more like secondary AML.
298
00:20:05,800 --> 00:20:08,520
Secondary to what?
A toxin of some sort.
299
00:20:08,520 --> 00:20:10,560
Some industrial chemical,
for example,
300
00:20:10,560 --> 00:20:14,560
or chemotherapy for
a different cancer.
301
00:20:14,560 --> 00:20:17,440
Right. And that can occur years
after the original exposure.
302
00:20:17,440 --> 00:20:19,440
Decades, in some cases.
303
00:20:19,440 --> 00:20:23,000
So, there may be other victims,
all exposed to the same thing?
304
00:20:25,040 --> 00:20:26,400
Makes sense.
305
00:20:28,080 --> 00:20:32,120
BUZZING
306
00:20:45,280 --> 00:20:46,440
Can I help you?
307
00:20:46,440 --> 00:20:48,480
They told me Wilfred is here.
308
00:20:48,480 --> 00:20:50,320
Can I see him, yeah?
309
00:20:50,320 --> 00:20:52,520
Er, you are? Family.
310
00:20:54,800 --> 00:20:56,360
Do you want to take a seat?
311
00:20:56,360 --> 00:20:59,560
Will I be able to sit with him
for a bit or...? I'll just check.
312
00:21:09,040 --> 00:21:11,360
I've found Rahul's murder weapon.
313
00:21:11,360 --> 00:21:15,120
One DNA profile matching Rahul,
one matching Wilfred,
314
00:21:15,120 --> 00:21:16,880
just like we found at the scene.
315
00:21:16,880 --> 00:21:18,880
But there's a third profile.
316
00:21:20,640 --> 00:21:22,760
Yep. Simi Jacobs.
317
00:21:22,760 --> 00:21:24,800
Simi? He's here!
318
00:21:24,800 --> 00:21:27,720
What do you mean he's here?
He wants to see Wilfred's body.
319
00:21:42,800 --> 00:21:45,600
This places Simi at the scene
of Rahul's murder.
320
00:21:45,600 --> 00:21:47,600
We need to keep him here.
321
00:21:47,600 --> 00:21:49,200
Call DI Cracknell.
322
00:21:53,080 --> 00:21:55,600
So, hang on. Simi Jacobs just
turned up at the lab.
323
00:21:55,600 --> 00:21:57,760
One needle injected into
three people.
324
00:21:57,760 --> 00:21:59,200
Better get down here.
325
00:21:59,200 --> 00:22:01,200
Simi had a puncture wound
to his neck.
326
00:22:01,200 --> 00:22:04,160
Rahul was stabbed in the chest,
but Wilfred?
327
00:22:04,160 --> 00:22:05,960
And if Simi got in a fight
with Rahul,
328
00:22:05,960 --> 00:22:07,920
why is Wilfred's blood spattered?
329
00:22:07,920 --> 00:22:10,600
Wilfred would have to have
been in the room as well.
330
00:22:10,600 --> 00:22:12,600
Maybe he was. Genetically speaking.
331
00:22:13,920 --> 00:22:16,440
What if that needle only stabbed
two people?
332
00:22:16,440 --> 00:22:19,320
Then one of them has two different
types of DNA. Exactly.
333
00:22:19,320 --> 00:22:20,880
Huh? No, for that to work, it would
334
00:22:20,880 --> 00:22:23,600
mean Simi's walking around with
Wilfred's blood inside him.
335
00:22:23,600 --> 00:22:25,480
That's ridiculous. Is it?
336
00:22:27,600 --> 00:22:30,760
Bone marrow transplant.
And Wilfred was the donor.
337
00:22:30,760 --> 00:22:34,560
So, Simi's blood has Wilfred's DNA.
338
00:22:42,080 --> 00:22:43,800
Do you want to come this way? Yeah.
339
00:22:48,240 --> 00:22:49,320
Just there.
340
00:22:52,400 --> 00:22:55,160
Can I get you a tea?
A glass of water or...?
341
00:22:55,160 --> 00:22:57,040
Oh, no, no!
342
00:22:57,040 --> 00:22:58,080
Thanks.
343
00:23:01,040 --> 00:23:03,440
You said that Wilfred was family?
344
00:23:03,440 --> 00:23:05,200
That's right.
345
00:23:05,200 --> 00:23:06,840
Was he a close relative?
346
00:23:08,480 --> 00:23:10,800
You ask a lot of questions.
347
00:23:10,800 --> 00:23:12,480
Remember me?
348
00:23:14,280 --> 00:23:16,400
I examined you at the station.
349
00:23:16,400 --> 00:23:17,720
I saw a scar on your chest.
350
00:23:17,720 --> 00:23:19,360
That's a Hickman line scar.
351
00:23:20,960 --> 00:23:23,280
Did you have a bone marrow
transplant as a kid?
352
00:23:24,720 --> 00:23:26,520
Yeah, I'm going to go.
353
00:23:26,520 --> 00:23:29,360
Simi, we found your blood at
the scene of Rahul's murder.
354
00:23:31,360 --> 00:23:32,600
Did you kill him?
355
00:23:35,440 --> 00:23:40,120
No, no, no. He... He came at me!
He was insane!
356
00:23:40,120 --> 00:23:41,440
It was an accident!
357
00:23:45,520 --> 00:23:47,240
I just wanted to protect Wilfred.
358
00:23:49,400 --> 00:23:52,200
Wilfred saved my life
when I was a kid.
359
00:23:52,200 --> 00:23:55,240
But you know what? He could only do
that because he was a match.
360
00:23:55,240 --> 00:23:58,120
People have transplants from their
brothers or mothers or whatever
361
00:23:58,120 --> 00:24:01,040
because they're a match.
I had no-one.
362
00:24:02,440 --> 00:24:05,520
How did you find him? There's this
charity attached to our church.
363
00:24:05,520 --> 00:24:07,520
They helped us get
the transplant records.
364
00:24:09,520 --> 00:24:11,240
Only it turns out Wilfred was sick.
365
00:24:12,440 --> 00:24:14,640
Were there others? Yeah.
366
00:24:14,640 --> 00:24:17,680
I mean, loads of people in his
village died from the same thing.
367
00:24:19,680 --> 00:24:21,320
We found Wilfred in time.
368
00:24:23,880 --> 00:24:25,320
So we thought.
369
00:24:27,240 --> 00:24:29,400
What?
370
00:24:29,400 --> 00:24:31,120
You're not going to let me see him?
371
00:24:35,200 --> 00:24:37,920
Simi.
372
00:24:37,920 --> 00:24:39,160
There he is.
373
00:24:59,680 --> 00:25:03,120
Ah, afternoon! Present from
DI Cracknell -
374
00:25:03,120 --> 00:25:05,960
all the rubbish from
Simi Jacobs' address.
375
00:25:05,960 --> 00:25:07,440
Thought you might want to take
a look
376
00:25:07,440 --> 00:25:09,240
in case you find anything relevant.
377
00:25:09,240 --> 00:25:13,600
Joy. Can I introduce Reverend Kanu?
You've already met Jack.
378
00:25:13,600 --> 00:25:17,640
This is Dr Nikki Alexander
and Dr Adam Yuen. Hello.
379
00:25:17,640 --> 00:25:21,040
Reverend Kanu runs the charitable
organisation that was responsible
380
00:25:21,040 --> 00:25:22,920
for bringing Wilfred to the UK.
381
00:25:22,920 --> 00:25:24,720
I have some photos from our trip.
382
00:25:24,720 --> 00:25:28,440
Sergeant Galloway thinks
they might help you. Thank you.
383
00:25:28,440 --> 00:25:30,880
I have to warn you,
they're not pretty.
384
00:25:34,040 --> 00:25:36,280
Tell me how Mr Okoye came to
be here.
385
00:25:37,880 --> 00:25:42,080
My church runs a charity that helps
arrange treatment in the UK.
386
00:25:42,080 --> 00:25:44,880
They raise money, get doctors to
volunteer, whatever.
387
00:25:46,360 --> 00:25:48,720
Wilfred's case was kind of special.
388
00:25:48,720 --> 00:25:52,400
I mean, he helped me years ago,
and now he needed my help.
389
00:25:52,400 --> 00:25:54,720
The local newspaper picked up
the story, it got a lot
390
00:25:54,720 --> 00:25:58,120
of publicity. So, the hospital
agreed to treat him.
391
00:25:58,120 --> 00:26:00,600
And he stayed at your flat? Yeah.
392
00:26:02,840 --> 00:26:05,720
Nobody told me he don't
speak English.
393
00:26:05,720 --> 00:26:08,560
I couldn't tell him anything.
394
00:26:08,560 --> 00:26:11,800
He didn't know who I was,
what he did for me.
395
00:26:14,160 --> 00:26:16,960
Then I learnt that he's under
the care of this Rahul guy.
396
00:26:18,800 --> 00:26:23,600
I have travelled widely in Africa
as part of my ministry,
397
00:26:23,600 --> 00:26:28,480
and yet nothing could have prepared
me for what we found in Bwendora.
398
00:26:31,360 --> 00:26:34,640
The town is remote, even by
African standards.
399
00:26:36,120 --> 00:26:39,360
There is only very basic
health care.
400
00:26:39,360 --> 00:26:42,160
It became clear there was a
lot of sickness.
401
00:26:43,960 --> 00:26:46,760
This man died within hours of
our arrival.
402
00:26:47,920 --> 00:26:52,360
The illness causes bleeding
and rashes. Fever sometimes.
403
00:26:52,360 --> 00:26:54,520
What do the people think it's
caused by?
404
00:26:54,520 --> 00:26:57,640
There's a large pesticide factory
in the town.
405
00:26:57,640 --> 00:27:00,800
Many people think the water has
been contaminated.
406
00:27:00,800 --> 00:27:03,760
They organised protests.
407
00:27:03,760 --> 00:27:06,720
People think there has been
a cover-up.
408
00:27:06,720 --> 00:27:09,120
But the factory provides
a lot of employment.
409
00:27:10,480 --> 00:27:14,200
It is a very divisive issue.
410
00:27:14,200 --> 00:27:18,920
The illness has ripped the heart
out of the community.
411
00:27:18,920 --> 00:27:21,960
There are very few families it has
left untouched.
412
00:27:21,960 --> 00:27:23,920
And they've had no outside help?
413
00:27:23,920 --> 00:27:27,160
There is one western charity
which runs a clinic,
414
00:27:27,160 --> 00:27:29,040
but they only visit every
few months.
415
00:27:31,680 --> 00:27:32,880
Some charity.
416
00:27:35,680 --> 00:27:37,840
Oh, Lord.
417
00:27:37,840 --> 00:27:39,760
Enlighten our minds with your truth.
418
00:27:42,080 --> 00:27:45,240
Give us the strength and the wisdom
to seek justice.
419
00:27:46,920 --> 00:27:50,720
Shine your everlasting light into
our darkness.
420
00:27:53,080 --> 00:27:56,480
There's a lot of talk about Rahul,
all around the hospital.
421
00:27:56,480 --> 00:27:58,920
How the hospital is protecting him.
422
00:27:58,920 --> 00:28:02,360
How he messed up an operation
and no-one wants to work with him.
423
00:28:02,360 --> 00:28:05,080
And you thought he shouldn't operate
on Wilfred.
424
00:28:05,080 --> 00:28:09,080
The night before, I heard him
arguing with this woman,
425
00:28:09,080 --> 00:28:11,200
Dr Braithwaite.
426
00:28:11,200 --> 00:28:13,280
She told Rahul not to do
the operation
427
00:28:13,280 --> 00:28:16,080
and he just told her that
she couldn't stop him.
428
00:28:16,080 --> 00:28:18,600
The bag of rubbish that we
found at your home address.
429
00:28:18,600 --> 00:28:20,600
Was it from one of the offices?
430
00:28:20,600 --> 00:28:22,040
Yeah. Which one?
431
00:28:23,120 --> 00:28:24,520
All of them.
432
00:28:24,520 --> 00:28:26,960
I was looking for
something, anything,
433
00:28:26,960 --> 00:28:28,800
I could use against Rahul.
434
00:28:28,800 --> 00:28:31,280
And on the morning of the operation?
435
00:28:31,280 --> 00:28:34,240
I saw Wilfred getting prepared for
theatre and I panicked.
436
00:28:34,240 --> 00:28:36,000
I phoned Rahul.
437
00:28:36,000 --> 00:28:37,480
What did you say?
438
00:28:37,480 --> 00:28:39,840
I told him I had some information
on him.
439
00:28:39,840 --> 00:28:43,960
I thought I could threaten to reveal
what I knew if he did the operation.
440
00:28:43,960 --> 00:28:45,160
What information?
441
00:28:47,680 --> 00:28:50,760
I was bluffing. But I had
to stop him.
442
00:28:53,960 --> 00:28:55,720
Well, you certainly managed that.
443
00:29:10,920 --> 00:29:12,400
How's it going?
444
00:29:12,400 --> 00:29:15,800
Oh, I'm in my element rummaging
through the trash. You know me.
445
00:29:16,880 --> 00:29:19,240
Nothing much here, apart from
a criminally lax attitude
446
00:29:19,240 --> 00:29:20,280
to recycling.
447
00:29:22,480 --> 00:29:24,480
Adam's still here, is he?
448
00:29:24,480 --> 00:29:26,480
We wouldn't have got this far
without him.
449
00:29:26,480 --> 00:29:28,120
I want to trust him.
450
00:29:30,520 --> 00:29:31,640
What's that?
451
00:29:36,560 --> 00:29:37,600
Oh, my God.
452
00:29:39,080 --> 00:29:43,680
This was in that rubbish bag you
found at Simi Jacobs' place.
453
00:29:43,680 --> 00:29:46,800
It's Harry Fletcher's ECG,
taken the day of his operation.
454
00:29:46,800 --> 00:29:48,080
It's normal.
455
00:29:48,080 --> 00:29:51,920
And this is the ECG that
appeared in Fletcher's notes.
456
00:29:51,920 --> 00:29:55,000
Same date and time,
but grossly abnormal.
457
00:29:55,000 --> 00:29:58,800
We believe they were switched
to deflect blame from Rahul
458
00:29:58,800 --> 00:30:01,160
after the operation went wrong.
459
00:30:01,160 --> 00:30:03,120
So, there was a cover-up?
460
00:30:03,120 --> 00:30:05,840
Well, what's this got to do with
the murder investigation?
461
00:30:05,840 --> 00:30:08,800
Yeah, Simi Jacobs admitted to
the attack on Arnie Rahul.
462
00:30:08,800 --> 00:30:11,680
I mean, he claims it was an accident
as a result of self-defence.
463
00:30:11,680 --> 00:30:13,400
That fits with the
crime scene findings.
464
00:30:13,400 --> 00:30:15,760
So, how does this transplant fit in?
465
00:30:15,760 --> 00:30:18,520
Well, Simi was born with
sickle cell disease,
466
00:30:18,520 --> 00:30:22,680
and was treated with a bone marrow
transplant at St Jude's as a child.
467
00:30:22,680 --> 00:30:25,480
Wilfred donated his stem cells
for Simi's transplant.
468
00:30:25,480 --> 00:30:27,840
20 years later,
Wilfred gets leukaemia.
469
00:30:27,840 --> 00:30:29,720
We don't think
this is a coincidence.
470
00:30:29,720 --> 00:30:32,960
He had a type of leukaemia
that can be caused by over-exposure
471
00:30:32,960 --> 00:30:34,240
to certain drugs.
472
00:30:34,240 --> 00:30:37,640
There's a technique known as
mobilisation,
473
00:30:37,640 --> 00:30:40,520
which is designed to increase
production of stem cells.
474
00:30:40,520 --> 00:30:44,720
Normally, stem cell donation
involves giving a perfectly safe
475
00:30:44,720 --> 00:30:46,240
bone marrow stimulant.
476
00:30:46,240 --> 00:30:51,160
But whoever did this also gave
Wilfred high levels of chemotherapy,
477
00:30:51,160 --> 00:30:53,000
and did so repeatedly.
478
00:30:53,000 --> 00:30:55,360
They gave chemo? To a volunteer?
479
00:30:55,360 --> 00:30:57,520
To yield even more stem cells.
480
00:30:57,520 --> 00:30:59,760
What for? More transplants?
481
00:30:59,760 --> 00:31:04,680
Stem cells have the ability to
develop into any type of body cell.
482
00:31:04,680 --> 00:31:06,640
Brain, heart, blood -
you name it.
483
00:31:06,640 --> 00:31:08,960
So there's a huge range
of potential therapies
484
00:31:08,960 --> 00:31:12,520
in which they can be used,
one of which is transplantation.
485
00:31:12,520 --> 00:31:17,200
About ten years ago, Braithwaite
and her team identified stem cells
486
00:31:17,200 --> 00:31:19,400
that were very special indeed,
487
00:31:19,400 --> 00:31:22,960
capable of being turned into
what are called killer T-cells,
488
00:31:22,960 --> 00:31:27,040
part of the immune system, which can
be made to attack malignant tumours.
489
00:31:27,040 --> 00:31:29,400
The potential for this discovery
was enormous.
490
00:31:29,400 --> 00:31:31,720
These magic cells
all had the same gene,
491
00:31:31,720 --> 00:31:36,040
a gene we think might be common
in Wilfred's town.
492
00:31:36,040 --> 00:31:39,840
They went looking for transplant
donors to treat people like Simi,
493
00:31:39,840 --> 00:31:42,640
but what they discovered
was something much bigger,
494
00:31:42,640 --> 00:31:44,760
so they went back for more,
and more.
495
00:31:44,760 --> 00:31:47,400
Basically they were flogging him
for every last stem cell
496
00:31:47,400 --> 00:31:49,800
he could produce.
Him and all the others.
497
00:31:49,800 --> 00:31:52,120
Wilfred's town was basically
a stem cell farm.
498
00:31:52,120 --> 00:31:55,560
Can you prove Wilfred
was given the stimulating drugs?
499
00:31:55,560 --> 00:31:58,760
It may be possible,
but that's way out of my league.
500
00:32:00,480 --> 00:32:02,360
Sounds like we need
a second opinion.
501
00:32:22,360 --> 00:32:23,680
Thank you, Professor.
502
00:32:23,680 --> 00:32:25,320
Not at all.
It's very good to see you.
503
00:32:25,320 --> 00:32:26,840
Thank you.
Oh, he's away!
504
00:32:28,680 --> 00:32:32,120
Adam, hello again.
Hello. This is Dr Nikki Alexander.
505
00:32:32,120 --> 00:32:34,480
Hello. How do you do?
And you've already met DI Cracknell.
506
00:32:34,480 --> 00:32:36,080
Yes, of course. This way.
507
00:32:37,040 --> 00:32:38,720
That was Alfie.
508
00:32:38,720 --> 00:32:42,840
He's one of our early trial patients
- osteosarcoma.
509
00:32:42,840 --> 00:32:44,960
When he was referred to us,
he was in a hospice
510
00:32:44,960 --> 00:32:48,520
on palliative treatment,
expected to die within weeks.
511
00:32:48,520 --> 00:32:50,920
Please. That was two years ago.
512
00:32:52,320 --> 00:32:53,680
He's now disease-free.
513
00:32:56,440 --> 00:32:59,920
We wanted to show you some
bone marrow samples from Mr Okoye.
514
00:32:59,920 --> 00:33:02,160
He was moved from St Jude's
to be treated here.
515
00:33:10,640 --> 00:33:12,600
Hmm.
516
00:33:12,600 --> 00:33:14,240
Secondary leukaemia.
517
00:33:17,120 --> 00:33:18,600
They look very unusual.
518
00:33:18,600 --> 00:33:21,440
Mr Okoye was a stem cell donor.
519
00:33:21,440 --> 00:33:23,160
Was he?
520
00:33:23,160 --> 00:33:26,400
We were wondering
if it might be stimulated.
521
00:33:26,400 --> 00:33:27,760
You mean Cyclo-G?
522
00:33:29,080 --> 00:33:30,560
Oh, dear.
523
00:33:30,560 --> 00:33:34,120
Yes, it's possible.
524
00:33:34,120 --> 00:33:37,040
Is there any way we can confirm it?
525
00:33:37,040 --> 00:33:39,920
You would need to look into
the genetics of his blood cells.
526
00:33:39,920 --> 00:33:42,040
There are some telltale signs.
527
00:33:42,040 --> 00:33:45,400
We have several world experts
in cytogenetics here.
528
00:33:45,400 --> 00:33:47,640
They'd be happy to help.
529
00:33:47,640 --> 00:33:50,640
Your cancer therapies are based
on Braithwaite's stem cell research,
530
00:33:50,640 --> 00:33:54,760
are they not?
Yes. Yes. I've never denied it.
531
00:33:54,760 --> 00:33:57,440
Hers was an extraordinary
piece of work.
532
00:33:58,600 --> 00:34:01,680
She tried for years to turn it into
a practical treatment,
533
00:34:01,680 --> 00:34:06,280
but, in the end, she was stumped
by the obvious problem.
534
00:34:06,280 --> 00:34:08,160
The limited supply of donors.
535
00:34:08,160 --> 00:34:09,440
Precisely.
536
00:34:09,440 --> 00:34:13,840
So, what we brought to the party
is called gene editing.
537
00:34:15,080 --> 00:34:18,720
We found a way of inserting
the special gene
538
00:34:18,720 --> 00:34:21,120
into any old stem cell,
and the result is...
539
00:34:22,200 --> 00:34:23,680
Well, you met Alfie.
540
00:34:24,760 --> 00:34:27,240
What is your relationship
to Emily Braithwaite?
541
00:34:28,840 --> 00:34:30,360
Yes.
542
00:34:30,360 --> 00:34:33,520
Well, I suppose you'd say
we're rivals.
543
00:34:33,520 --> 00:34:37,400
She's never forgiven me
for succeeding where she failed.
544
00:34:37,400 --> 00:34:41,400
But I'm afraid her star
has been waning for some time.
545
00:34:41,400 --> 00:34:42,840
What makes you say that?
546
00:34:45,120 --> 00:34:47,120
She came to ask for my help.
547
00:34:47,120 --> 00:34:50,840
Believe me,
that alone suggests desperation.
548
00:34:50,840 --> 00:34:54,560
She had just lost a very large
research grant.
549
00:34:54,560 --> 00:34:57,120
Is it possible that Braithwaite
poisoned Mr Okoye
550
00:34:57,120 --> 00:35:00,480
and everyone else in his town
to get more stem cells?
551
00:35:00,480 --> 00:35:03,200
That's a serious accusation.
552
00:35:03,200 --> 00:35:05,040
Everything's falling apart.
553
00:35:05,040 --> 00:35:07,440
So, like a gambler,
she risks more and more,
554
00:35:07,440 --> 00:35:10,120
desperate for that big win
to get herself back on top.
555
00:35:20,000 --> 00:35:25,600
THEY CONFER
556
00:35:28,760 --> 00:35:30,400
PHONE PINGS
557
00:36:05,600 --> 00:36:07,200
Now what?
Excuse me?
558
00:36:08,360 --> 00:36:11,600
You do realise my career is over?
And that's my fault?
559
00:36:11,600 --> 00:36:13,480
There's got to be a way out of this.
560
00:36:13,480 --> 00:36:14,800
You owe me that at least.
561
00:36:16,080 --> 00:36:18,720
You want Auntie Emily
to make it better?
562
00:36:20,240 --> 00:36:24,440
All those years I stuck up for you
with your father.
563
00:36:24,440 --> 00:36:27,360
You messed up. Again.
564
00:36:27,360 --> 00:36:29,120
For once in your life, own it.
565
00:36:31,400 --> 00:36:33,000
I don't get it.
566
00:36:33,000 --> 00:36:34,520
You and Rahul.
567
00:36:34,520 --> 00:36:36,720
You go to all these lengths
to protect his reputation,
568
00:36:36,720 --> 00:36:39,480
yet you show no interest
in who might have killed him.
569
00:36:39,480 --> 00:36:41,840
You don't even seem to even care
that he's dead!
570
00:36:43,240 --> 00:36:45,800
Maybe I've learnt to
bury my emotions.
571
00:36:47,640 --> 00:36:48,840
You should try it.
572
00:36:50,760 --> 00:36:52,840
You know they're onto you,
573
00:36:52,840 --> 00:36:55,560
and I'm not going to help you
this time.
574
00:36:55,560 --> 00:36:56,840
Oh, please.
575
00:36:58,440 --> 00:36:59,880
This is so painful.
576
00:37:06,640 --> 00:37:09,080
So, all roads lead to Braithwaite.
577
00:37:09,080 --> 00:37:11,400
Yes, but it's all circumstantial.
578
00:37:11,400 --> 00:37:14,080
There's nothing directly
connecting her to Wilfred.
579
00:37:14,080 --> 00:37:16,440
If you can find me something
concrete, I'll bring her in,
580
00:37:16,440 --> 00:37:18,360
but until then,
it's just speculation.
581
00:37:18,360 --> 00:37:20,760
Adam, where did you get to?
582
00:37:20,760 --> 00:37:23,320
Rahul's conduct during
Fletcher's operation amounted to
583
00:37:23,320 --> 00:37:25,280
criminal negligence.
584
00:37:25,280 --> 00:37:27,360
He could have been charged
for manslaughter.
585
00:37:27,360 --> 00:37:28,720
Well, he's dead.
586
00:37:28,720 --> 00:37:30,680
What if Braithwaite covered it up?
587
00:37:30,680 --> 00:37:33,080
That's attempting to pervert
the course of justice.
588
00:37:33,080 --> 00:37:34,600
Which means you can arrest her.
589
00:37:34,600 --> 00:37:37,680
Oh, and how do we know that
Braithwaite swaps the ECG?
590
00:37:37,680 --> 00:37:40,080
We can't. There are several
sets of prints on the trace,
591
00:37:40,080 --> 00:37:41,680
one of which could be Braithwaite's.
592
00:37:41,680 --> 00:37:44,120
Exactly, so we can't just arrest her
on the off-chance that
593
00:37:44,120 --> 00:37:45,560
her prints are on there.
I know.
594
00:37:45,560 --> 00:37:47,040
ADAM: I met her for a drink.
595
00:37:51,000 --> 00:37:52,760
Her prints are on this glass.
596
00:37:52,760 --> 00:37:56,000
When you find that they are
the same as the sets on the ECG,
597
00:37:56,000 --> 00:37:58,760
then you can arrest her.
That's not admissible as evidence!
598
00:37:58,760 --> 00:38:00,400
It doesn't have to be.
599
00:38:01,920 --> 00:38:05,320
How do we know for sure
she touched this glass?
600
00:38:05,320 --> 00:38:07,520
Well, you're just going to
have to trust me.
601
00:38:54,160 --> 00:38:55,640
You two go round the back.
602
00:38:59,600 --> 00:39:01,080
DOORBELL RINGS
603
00:39:07,280 --> 00:39:09,360
Her car's here.
Looks like she's home.
604
00:39:12,440 --> 00:39:13,480
No letterbox.
605
00:39:17,960 --> 00:39:19,320
Dr Braithwaite?
606
00:39:20,320 --> 00:39:22,680
DS Galloway.
Could you open the door, please?
607
00:39:27,040 --> 00:39:29,160
Police!
Dr Braithwaite?
608
00:39:41,280 --> 00:39:42,360
Shit.
609
00:39:48,640 --> 00:39:50,280
No sign of external injury.
610
00:39:52,120 --> 00:39:55,520
Both front and back doors
were locked from the inside.
611
00:39:55,520 --> 00:39:58,120
There's no signs
of forced entry.
612
00:39:58,120 --> 00:39:59,640
Everything's neat and tidy.
613
00:40:01,800 --> 00:40:03,160
Sudden chest pain, maybe?
614
00:40:04,680 --> 00:40:05,720
Or suicide.
615
00:40:38,160 --> 00:40:41,040
Nikki. Adam. Look at these.
616
00:40:46,560 --> 00:40:49,760
Two samples
with Wilfred Okoye's name on.
617
00:41:12,760 --> 00:41:14,720
Look at this.
618
00:41:14,720 --> 00:41:17,000
The boiler's locked out.
619
00:41:17,000 --> 00:41:18,920
Yeah. Mine does that all the time.
620
00:41:18,920 --> 00:41:20,160
Bloody things.
621
00:41:58,560 --> 00:42:01,120
Heart weighs 380g.
622
00:42:27,280 --> 00:42:30,120
Evidence of left ventricular
hypertrophy.
623
00:42:31,480 --> 00:42:32,960
Valves unremarkable.
624
00:42:36,280 --> 00:42:40,120
Left anterior descending
coronary artery.
625
00:42:40,120 --> 00:42:43,160
Moderate stenosis,
no evidence of thrombus.
626
00:42:51,560 --> 00:42:54,200
The toxicology
was entirely negative,
627
00:42:54,200 --> 00:42:56,760
apart from a modest level
of alcohol.
628
00:42:56,760 --> 00:43:00,720
No paracetamol,
no benzodiazepines, nothing.
629
00:43:00,720 --> 00:43:04,320
So this, together with the absence
of pills and containers
630
00:43:04,320 --> 00:43:07,280
at the address, and the absence
of any needle marks on the body,
631
00:43:07,280 --> 00:43:10,440
leads me to conclude that death
was not as a result
632
00:43:10,440 --> 00:43:13,000
of suicide or poisoning.
633
00:43:13,000 --> 00:43:16,480
In fact, the only significant
finding from the postmortem
634
00:43:16,480 --> 00:43:19,440
examination is moderate ischaemic
heart disease,
635
00:43:19,440 --> 00:43:22,880
together with hypertrophy of the
septum and left ventricular wall.
636
00:43:22,880 --> 00:43:25,840
But no evidence of
coronary thrombosis?
637
00:43:25,840 --> 00:43:28,800
The ventricular wall thickness...
Heart attack. ..and the degree
638
00:43:28,800 --> 00:43:32,600
of myocardial disarray on microscopy
are borderline
639
00:43:32,600 --> 00:43:34,640
for a diagnosis of HCM.
640
00:43:34,640 --> 00:43:37,560
What's that?
Hypertrophic cardiomyopathy.
641
00:43:37,560 --> 00:43:40,920
It's an inherited heart condition
that can lead to sudden death.
642
00:43:40,920 --> 00:43:42,800
Fabrice Muamba.
Yes.
643
00:43:44,720 --> 00:43:48,440
Bolton Wanderers versus Tottenham.
FA Cup quarterfinal, 2012.
644
00:43:48,440 --> 00:43:50,400
He collapsed on the pitch.
Nearly died.
645
00:43:50,400 --> 00:43:52,280
Well, technically he did.
646
00:43:52,280 --> 00:43:54,320
In cases of high stress or exercise,
647
00:43:54,320 --> 00:43:58,440
the heart can lead into an abnormal
rhythm, which can be fatal.
648
00:43:58,440 --> 00:44:01,360
And Emily Braithwaite
was under a lot of stress.
649
00:44:01,360 --> 00:44:05,840
So it is possible that this caused
a dysrhythmic event...
650
00:44:05,840 --> 00:44:08,640
Heart attack. ..that led to
her death, don't you think?
651
00:44:12,640 --> 00:44:14,640
How come she didn't have
a letterbox?
652
00:44:14,640 --> 00:44:17,000
It's a passive house.
It's so well-insulated,
653
00:44:17,000 --> 00:44:19,680
it doesn't need heating.
You heat it up just by living in it.
654
00:44:19,680 --> 00:44:21,440
But it has to be really airtight.
655
00:44:21,440 --> 00:44:23,560
It's like living in a bubble.
656
00:44:23,560 --> 00:44:26,760
All the air goes in and out through
a single ventilation system.
657
00:44:28,400 --> 00:44:31,320
But why would the boiler lock out?
658
00:44:31,320 --> 00:44:35,760
What if it was faulty and produced
a lot of carbon monoxide?
659
00:44:35,760 --> 00:44:38,120
No carbon monoxide in
the toxicology.
660
00:44:42,400 --> 00:44:45,000
She's a suspect in a murder case.
She conveniently dies.
661
00:44:45,000 --> 00:44:46,840
What if others were involved?
662
00:44:46,840 --> 00:44:48,960
If you can tell me how they did it,
I'll believe you,
663
00:44:48,960 --> 00:44:52,480
but until then,
it's looking like natural causes.
664
00:44:52,480 --> 00:44:56,040
Right, then, provisional assumption
is that Braithwaite
665
00:44:56,040 --> 00:44:58,760
was guilty of conspiracy
to murder Wilfred Okoye,
666
00:44:58,760 --> 00:45:01,720
as well as perverting the course
of justice in the Fletcher case.
667
00:45:01,720 --> 00:45:02,920
What about Simi?
668
00:45:02,920 --> 00:45:06,960
That's up to the CPS, whether
they buy a self-defence plea.
669
00:45:06,960 --> 00:45:08,480
I'll keep you posted.
670
00:45:26,480 --> 00:45:28,760
So this is where you've been hiding.
671
00:45:30,960 --> 00:45:32,760
Adam told you, then?
672
00:45:32,760 --> 00:45:35,280
Oh, yeah. He told me everything.
673
00:46:31,680 --> 00:46:33,080
I don't get it.
674
00:46:33,080 --> 00:46:36,080
How could someone like Braithwaite
justify it to herself,
675
00:46:36,080 --> 00:46:37,400
let alone anyone else?
676
00:46:37,400 --> 00:46:39,920
They get fixated on the prize,
don't they?
677
00:46:39,920 --> 00:46:43,480
The breakthrough, and all
the acclaim that goes with it. Mm.
678
00:46:44,600 --> 00:46:47,800
Did you ever want to do something
like that? Fancy research job?
679
00:46:48,800 --> 00:46:50,640
I think you'd be really good
at that.
680
00:46:53,560 --> 00:46:54,600
I don't know.
681
00:46:55,720 --> 00:46:57,600
It's more Adam's world.
Mm.
682
00:46:58,760 --> 00:46:59,960
Not any more.
683
00:47:01,640 --> 00:47:04,400
You can see how liberated he's been.
684
00:47:04,400 --> 00:47:07,480
He's carried that secret around
for so long.
685
00:47:07,480 --> 00:47:11,040
Well, he's stopped trying to
be all things to all men.
686
00:47:11,040 --> 00:47:13,960
And I'll tell you,
he loves beating himself up.
687
00:48:13,400 --> 00:48:16,920
Hi. I'm working on the case
of Wilfred Okoye.
688
00:48:16,920 --> 00:48:19,200
I was wondering if I could get
his microbiology results
689

Date of birth is 9/7/66.
691
00:48:28,440 --> 00:48:31,040
I just need to, er,
speak to my supervisor.
692
00:48:31,040 --> 00:48:32,280
OK. Thank you.

696

What?

What are we looking at?
698
00:49:27,320 --> 00:49:30,160
Wilfred's blood cultures.
Microbiology report.
699
00:49:33,000 --> 00:49:34,240
Hang on.
700
00:49:35,560 --> 00:49:39,280
The antibiotic sensitivities
have been reversed.
701
00:49:39,280 --> 00:49:40,760
Who's done that? Braithwaite?
702
00:49:40,760 --> 00:49:43,320
Couldn't be. These are from
the Cowley institute.
703
00:49:45,960 --> 00:49:47,560

You know Emily Braithwaite
died yesterday?
709
00:50:43,120 --> 00:50:47,360
What? Uh, no. How did it happen?
710
00:50:47,360 --> 00:50:50,520
Unknown. Found dead in a house
that was bolted from the inside.
711
00:50:52,040 --> 00:50:54,600
Oh, look, an oxygen analyser.
712
00:50:56,000 --> 00:50:57,880
Do you always keep one of those
in your car?
713
00:50:57,880 --> 00:50:59,720
I use it for various things.
714
00:50:59,720 --> 00:51:03,000
So Emily died just as
you convinced us she was guilty.
715
00:51:03,000 --> 00:51:05,720
Her work was based on exploitation.
716
00:51:05,720 --> 00:51:07,920
Well, she can't deny that now,
can she?
717
00:51:07,920 --> 00:51:09,280
Well, whatever happened,
718
00:51:09,280 --> 00:51:12,560
I'm sure forensic science
will find the answer.
719
00:51:12,560 --> 00:51:16,040
Mm. Then I realised just how much
liquid nitrogen you go through here.
720
00:51:16,040 --> 00:51:18,040
Two deliveries in three days?
721
00:51:20,200 --> 00:51:23,600
I mean,
that is some evil genius stuff.
722
00:51:23,600 --> 00:51:25,760
Pretty quick and very clean.
723
00:51:25,760 --> 00:51:29,360
Except the pilot light in the boiler
went out at Braithwaite's house.
724
00:51:29,360 --> 00:51:30,760
Otherwise, the perfect crime.
725
00:51:32,000 --> 00:51:33,400
Are you insane?
726
00:51:33,400 --> 00:51:36,440
Oh, sorry. That's forensic science.
Get out.
727
00:51:40,720 --> 00:51:43,400
Braithwaite had Wilfred's
blood samples. She was onto you.
728
00:51:44,680 --> 00:51:46,480
My research is changing lives.
729
00:51:46,480 --> 00:51:48,200
She never made the crucial
breakthrough,
730
00:51:48,200 --> 00:51:49,760
but then again, neither did you.
731
00:51:49,760 --> 00:51:51,920
You reckon you'll crack it
any minute now, don't you?
732
00:51:51,920 --> 00:51:54,400
You just have to keep going,
keep blasting innocent men
733
00:51:54,400 --> 00:51:56,880
and women with poisonous drugs,
and then you'll get there.
734
00:51:56,880 --> 00:51:59,640
You know nothing. There's no
gene editing going on here.
735
00:51:59,640 --> 00:52:02,080
Your magic treatments are all
from stem cells that you get
736
00:52:02,080 --> 00:52:03,560
from killing people like Wilfred.
737
00:52:03,560 --> 00:52:07,240
When childhood cancer is
a thing of the past thanks to me,
738
00:52:07,240 --> 00:52:09,520
no-one will care.
739
00:52:09,520 --> 00:52:12,080
That's what it's all about,
isn't it?
740
00:52:12,080 --> 00:52:16,560
It's not about the money or
the power. It's about the prestige.
741
00:52:18,200 --> 00:52:20,800
So what are you going to do
about it, Adam?
742
00:52:20,800 --> 00:52:22,800
Mm? You're discredited.
743
00:52:22,800 --> 00:52:24,240
You're getting struck off.
744
00:52:25,480 --> 00:52:28,120
Of course I know!
745
00:52:28,120 --> 00:52:29,280

who you're dealing with.

Adam? What's happening?
751
00:52:49,640 --> 00:52:53,040
Cowley's the one exploiting Wilfred
and the rest of the donors.
752
00:52:53,040 --> 00:52:55,240
And he killed Braithwaite
with liquid nitrogen.
753
00:52:55,240 --> 00:52:57,360
He poured it in the vent
of her airtight house,
754
00:52:57,360 --> 00:53:00,840
turning it into a gas chamber.
She suffocated.
755
00:53:00,840 --> 00:53:03,840
Cowley did a deal with Rahul
to kill Wilfred during surgery.
756
00:53:03,840 --> 00:53:06,760
And when that failed, he attacked
Wilfred with the bacteria...
757
00:53:09,080 --> 00:53:11,320
..to make sure he switched
the micro reports
758
00:53:11,320 --> 00:53:13,320

wouldn't work.
