How was your day? Someone
murdered a tour guide in a church.

I mean, in terms
of our investigation.

Well, I've actually been looking
over the original crime scene.

No, John, what you
were supposed to do today

is get closer to DI Carter.

This Russell character
magically appeared

at the exact same time
as James vanished.

I was engaged.

She died.

Her name was Mandy Ziegler.

A-As in...?

Helped to fast-track
my transfer.

That's all I've
ever asked of him.

The Sinclair case

is Roger Sinclair.

Single man, disturbed a burglar,

who killed himself in a
panic of self-preservation.

Sinclair was a
conspiracy theorist,

and a pretty batty one at that.

I have been looking into this
guy they arrested, Rhys Bowen.

He lives with his mother.

He was with me
that whole evening,

as I told the police,

but they wouldn't believe me.

He's dead! I was supposed
to talk to him today.

What if they knew that?

The man was facing life in
prison for a crime he didn't commit.

Shadowy figures

orchestrating a suicide

inside a guarded prison cell?

No, it's too much,

i-it's too big.

Symphony 5 in C Minor
by Ludwig van Beethoven

All right?

Oh, my God.

Marty! Marty!

John, wake up.

Argh! W-What you doing?

The famous detective awakes!

Congratulations. Page five.

That's me.

Not according to that it isn't.

According to that, it's
"supercop" DCI James Taylor.

"Supercop?" Is
that what it says?

What on earth were you thinking?

How's this my fault?

I didn't know I was
going to be in the paper.

You gave them a quote, John!

"As with most
investigations of this nature,

"it was simply a case of
whittling down the variables."

That woman was a journalist?!

Who did you think she was?

A fan?

You can't go plastering yourself
all over the newspaper like this!

God only knows who
might have seen this.

Maybe Dad has.

And if he has, maybe
he'll get in touch.

Oh, Henry, you don't understand,

we have to be careful
about this sort of thing.

Why? Because he told us to?

He also told us to leave town.

We didn't do that, did we?

If he sees we haven't been
following his instructions,

maybe it'll force his hand.

Bring him home.

You do want him to come
home, don't you, Mum?

Henry!

Forget it.

Oh, it really does
say "supercop".

Have you got anywhere with
that cypher in James' notebook?

Anywhere at all?

Great. Good. So,
since you've been here,

you've solved four murders and
not a single letter of that thing?

James is a lot cleverer
than most murderers,

not to mention me.

James is no cleverer
than you. He never was.

He's just much more...

You know what I mean.

Look, the cypher's a puzzle.

Solving puzzles is
literally what you do.

I need the source code.

Well, work out what
and where it is, then!

Look, like it or not,

you and James
think in the same way.

Where would you hide it?

Probably in plain sight.

Right, well, look there, then!

OK.

Can I get up now, please?

Yes.

I'm in my pyjamas.

Do me a favour, John.

Don't solve any murders today.

I'll try really hard
not to - I promise.

Health and safety.

Can't let you in without it.

Right. Do they work?

Was he wearing one?

Well...

Guv, it's almost certainly
a workplace accident.

Let's just get it over
with, get it passed on

and get back to the station.

Morning, Guv. Sir.

Sergeant Finch is trying
to access the CCTV.

There are plenty of cameras
dotted around the site.

Staff-wise, there were
only five others here

at the time of the incident.

I don't think that's
quite right, sir.

Do you mind if I...?

Here, let me
just... Let me just...

Don't twist it. It
goes round the ears.

Five, including
you? No, it's just...

Did you see it?
No, but I heard it.

Marty! Call Connor!

No, careful! Argh!

Oh, sorry, sir. Ow! Oh,
sorry, sir. I think it's a hair.

Yeah, well, OK.
Yes, yes, constable.

I think the DCI can manage.

Why don't you go and
take some statements?

And perhaps you can
take us up to where he fell.

"Up"?

You scared of
heights, Detective?

Nobody's ever given me
a good reason not to be.

Running off a skeleton
crew at the moment,

at least for phase one.

It's a budget thing.

I promise there'll be some
more hands down the line.

So, who were the other
four on-site this morning?

Er...

Er, well...

It's that lot down there.

I'm going to need
a list of names.

Well, I can give you the rota.

You've got Gary Jennings.
He was on the mixers up here.

Marty! Call Connor!

Er, Zara Bassett, Ojay Turner -

they were next floor up.

Pretty much right
below where he, er...

Sorry, excuse me.

T-That sign had a skull on it.

What?

Oh, yeah, yeah,
don't worry about it.

This platform's fine.

I'm not actually sure
why that was up here -

it wasn't meant to be.

And then there was Stefan.

Polish kid.

He got the worst of it.

He hasn't been here that long.

He actually saw it.

And what about the deceased?

Er, Martin Symes. What can
you tell us? Marty? Not a lot.

He was a hard
worker, good laugh.

Bit of a lad. A
wind-up-merchant, you know?

Absolute tragedy.

There you go.

That's where he fell.

What was he actually
doing up here?

Beats me.

According to the rota,
nobody should've been.

Look, the bolts
have worked loose.

I mean, he must have
leant against it and...

Well, it certainly looks
like an accident, don't it?

Good. Agreed.

Can we go back down now?

What are you doing?!
Nothing, I was just...

Looks like the fuse
has blown on this thing.

Like we haven't had
enough setbacks already!

More skulls.

Why don't they
just say, "No entry"?

Why do they have to be
so graphic and portentous?

Actually, that one's not
meant to be up either.

It isn't?

Guv, is everything all right?

Can we please go back down now?

Ah, there you are, sirs.

Not much help, I'm afraid.

Didn't catch the accident.

This here's the last
footage, at around 6am.

Nobody was even on-site then.

They're motion sensitive.

Fox probably set it off.

Listen, is this going
to take much longer?

Look, I know you've got a
job to do, but so have we.

I've got half a dozen workers
out there sat around doing nothing.

Look, they're all shook-up,

but they want to work.

And we're on a tight schedule.

I'm afraid that's the
least of your problems.

What? What do you mean?

Well, for a start, one
of them is a murderer.

So, not an accident?
Are you sure?

Absolutely. Well, there
certainly were quiet a few things

that don't add up.

Like the warning signs
blocking various paths.

They're missing from the
CCTV earlier that morning,

meaning someone must've
put them up afterwards,

when there were only
five people on the site,

all of whom claim
it wasn't them.

Is that it?

Well, yes.

Oh, no! There's the generator
thing up where he fell!

That had been
deliberately tampered with,

completely re-wired.

How do you know that?

Well you don't have to
be a trained electrician

to know that red goes in
red, green goes in green

and blue goes in blue.

This was all over the place!

Red was in green,
green was in orange,

I don't even want to think
about where blue was going!

It was murder.

Believe me, I wish it wasn't.

Yes, well, I wish
it wasn't, too!

You'll be tied up for days now.

No, I won't.

There's only five suspects.
It shouldn't be hard.

Goodness, that article really
has gone to your head, hasn't it?

No! Well, I mean, it's always
nice to get positive feedback, but...

Oh, no, that computer
woman's here.

What computer woman?

Holly Pinder.

She almost caught
me this morning.

Caught you doing what?

Going through
the Sinclair report.

Shift, I need that computer.

I need to install
an update on it.

In fact, I need to install updates
on half the ones in the station,

so if you don't mind.

Er, just a second.

Just a second.

Er...

Wow.

That must've been some
serious porn you had on there.

Are you laughing?

No, sorry.

OK, good. Because I don't think
this woman likes me very much -

or James anyway.

She's always giving
me funny looks

and sarcastic answers to
perfectly normal questions.

Well, that could be a John
thing rather than a James thing.

I mean, let's be honest,

you've had funny looks and
sarcastic responses all your life.

Oh.

No, I didn't mean
that. I was just saying...

No, no, it's fine,
you're probably right.

I'd better go.

Ooh!

Look, I've nearly
lost a day already.

I'm not interested
in any of that, OK?

This happens to be a crime scene
that you're busy cementing over,

and I'm ordering you to stop.

You can't order
me to do anything.

Oh, she can. She's
really good at it.

Well, you are. Oh, here
comes re-enforcement.

Look, this has already been
cleared by your gaffer, all right?

So you take it up
with him if you need to.

Her.

Him, her, whatever.

Listen, love, I've worked
sites like this all my life

and I've seen a million
accidents like this one.

And yet they keep employing you!

What? You two, head
back to the station, please.

Sir.

We need to talk to everyone
that was on-site this morning.

Well, we're not downing tools.

Heaven forbid.

"Listen, love"?

I really hope he did it.

It'd bring me great
pleasure to arrest that man.

Yeah, but it's
my turn, isn't it?

You said it was my turn!

What?

This ain't coming
off our breaks, is it?

It's just a few questions.

All right. Well, you'd better
get on with them, then,

cos it was obviously
an accident.

It's not something we
want to talk about too much,

cos it could've been any
of us. It wasn't an accident.

Yeah, the foreman mentioned you.

What is it you're saying?

Do you think he was
pushed or something?

We certainly need to
explore the possibility,

if only to shut it down.

So, a good place to start
would be if either of you

know of any reason why
someone might want to harm Marty.

Aside from the fact that he
was an arsehole, you mean?

Christ, Zee!

Look, I wouldn't wish
this on my worst enemy,

but he was an arsehole.

She used to go out
with him. No, I didn't.

I went on one date with
him six months back,

cos he wouldn't take
"no" for an answer.

I think it was a bit more
than a date. Really?

Is that what he
told you all, is it?

Like I say, arsehole.

Look, you get it, all right?

He was a bit of a lad.

He worked hard, played hard
- just loved winding people up.

He was harmless.
It was all in good fun.

Tell that to Stefan.

Marty's idea of winding people
up involved convincing them

they were about to be deported.

Stefan Kaminski?

Yeah. Yeah, Marty had been
whacking over a load of emails to him,

saying he was from immigration

and talking about
work permits and that.

Had Stefan completely convinced.

Why on earth would he do that?

For a laugh.

No harm in it. It was a
joke. How is it a joke?

It doesn't follow any of the
normal or traditional structures

of a joke,

not as I've been led to
understand them anyway.

I guess everything's a joke as
long as you're not the butt of it.

And I'm guessing
you never have been?

Guess again. He once
had me totally convinced

that our syndicate
had won the lottery.

Made a ticket up and everything.

I was this close to asking
my girlfriend to marry me.

It was a lucky escape.

Yeah, you're telling
me. I meant for her.

You see, that's a joke.

You set up a false
premise, then you subvert it.

So, when did you both
get on-site this morning?

Seven-ish, for a 7:30 start.

And did either of you see Marty?

No.

Well... not until
it was too late.

And what about you? Yeah.

Yeah, I saw him. I spoke to him.

Yeah, I told your
little bobby this.

Only reason I was on
the mixer this morning

was cos Marty wanted
to swap with me.

I was meant to be on riveting.

Wait a minute, are you
saying that you were supposed

to be up there, where he fell?

No, riveting's on G5. That's F6.

I don't think anyone was
meant to be up there today.

Sorry, G5, F6?

Oh, the site's
divided up into zones.

There's always a rota
up when we get here,

but we often just chop
and change between us.

But if you're all always
swapping around,

how does anyone know
what anybody else is doing?

Sort of just becomes
second nature.

Instinctive. Yes, I see.

Like ants.

Excuse me? Well,
in a nest or a hive

where there are
thousands of organisms...

So, would either of you
happen to know which zone

we can locate
Stefan in right now?

Marty did apologise.

Ojay made him.

Too right I did!

Stefan here spent a
solid week convinced

he was being booted
out the country.

I don't mind a joke, me,

but this is a dangerous job.

Yeah, you don't want to be operating
heavy machinery next to a guy

with a head-full of
that sort of worry.

And... when exactly
was this apology?

Yesterday.

End of shift.

I said it was OK. And was it?

Doesn't matter now.

No.

I mean, nobody wanted this.

Someone did.

So, did either of you
see him this morning?

Yeah, spoke to him
first thing as it goes.

We were both in early.

He was whinging about the rota.

Wasn't happy with all
the swapsies going on.

Although he still
tried to swap with me.

I said, "No."

How about yourself? Did you
speak to Marty at all this morning?

No. I saw him, though.

Twice.

First time was about ten
minutes before the accident.

I was on brick-laying.

Tried to take a short
cut between E1 and H1,

but there was a
sign blocking my way

so I had to go find
another way to get round.

Marty was up
on the third floor -

testing the pneumatic
riveter, I think.

So, you say you saw him twice?

When was the second time?

Oh. Yes, of course.

I'm sorry, that
must have been...

It was.

I've never seen
another man die before.

It was so...

..sudden.

One minute, there was this...

..empty space before me and...

And then suddenly...

Er, Guv?

Guv!

Oh, er, sorry.

What is this, please?

What do you mean, "What is it?"

It's a chute, isn't it?

A chute, yes.

Where does it go?

It goes down.

You going to fill me
in on exactly what it is

we're looking for here, Guv?

Whatever is in it, of course.

The top of it is right next
to the crime-scene itself.

So it's possible
that something...

Look, do you think
we could start calling it

the "incident location"?

Only I'm starting to think
more and more that...

Aha! There! See?

What do you call that?

It's a plastic bottle.

It's for a water dispenser.

There's several
dotted around the site.

Yes, but what's
it doing in here?

It's a skip.

Traditionally that's
where you put rubbish,

like empty plastic bottles.

Or perhaps it was
a full plastic bottle

when it was taken up there,

then an empty one when it
was dropped down the chute.

Someone poured it
onto the generator.

You must've noticed
how wet the floor was.

That could've been...

You don't really expect to be
able to move a two-tonne skip,

do you, Guv?

Well, I was going
to give it a go. Yeah.

Oh, no!

That's no good.

That's no good at all!

What? Oh!

Guv, wait.

Wait, Guv.

Oi! Run, Forrest!

Guv, I really do think we
should entertain the possibility

that this was an accident.

Excuse me! Where...?

Where do you think
you're taking that?

That's evidence, isn't it?

They can't take away evidence,
can they? "Evidence" of what?

It's a burnt-out generator,
like I told you earlier.

What are you doing?

You've pulled all the
wires out! Yeah, to move it.

They were all in the
wrong place anyway.

Well, can you put them
all back again, please?

Put them back?

In the wrong place?

Forget it, I'll do it.

Er, it is safe?

Of course it's safe.
It's completely dead.

What's he...?

He can't actually remember

where each and every
one of those wires went?

Oh, believe me, he can.

There!

Are you a trained electrician?

As a matter of
fact, I am. Excellent.

If this was wired like this
and wasn't already dead,

what would happen
if you turned it on?

Well, the fuse would
blow. Which it did.

And what would happen to the
person who pressed the button?

And let's assume, for
the sake of argument,

that the generator
was wet at the time.

I don't know, they'd
get a very nasty shock,

but it wouldn't kill 'em.

Just knock them backwards,

straight into a safety rail

that had already had several of
its bolts deliberately worked loose?

Ahem. OK, then.

I want that generator
taken back off that truck.

Listen, mate... No,
you listen, mate.

This is a crime
scene, that is evidence.

It is not leaving this site.

And you're going to come with
us and answer some questions.

Understood?

Thank you. Guv.

So, this is everything
from his locker?

Yeah.

No idea what we're
supposed to do with it all.

Well, given your keenness to
remove evidence from the scene,

I'm surprised you
didn't just chuck it.

Oh, I see.

So, I do my job,

arrange for a burned out
generator to be replaced -

like it should be - and suddenly
that makes me a suspect?

You're a suspect because
you're one of only five people

who could've
committed the murder.

This is a Ludwig.

A what?

Hmm?

Oh, he's a world-famous
puzzle setter.

Quite the legend in his field.

These puzzles
have all been done.

Well, maybe some of the lads
have been doing them on their break.

Really?

None of them seemed
very puzzle-solvey.

Sorry? All right, moving on.

You said earlier you didn't think
anybody was on the site at 6am,

when the cameras went off.

What time did you get here?

Half past.

Nobody else was here.

Well, somebody was.

Because somebody had
spent the previous half hour

setting up the Rube
Goldbergian sequence of events

that would eventually
lead to Marty's death.

Unless that somebody was you.

What?

I don't even know what
Ruby-Golden-whatever is!

Have you ever played Mouse Trap?

The board game?

Hasbro, 1963?

No. Really?!

You've missed out.

What's he...?

Don't worry about him.

So, who was the first
person to arrive after you?

I should think it was Marty.

I didn't speak to him.

I was on a call.

At 6:30 in the morning?

I was checking out
flights if you must know.

Look, it's got nothing to
do with your investigation,

so I would appreciate if
you kept this to yourself.

But I've been offered
an interview for a new job,

overseeing the
construction of a luxury hotel.

Abroad. "Abroad" where?

Las Vegas. I shouldn't
have thought so.

I suspect that was just a joke.

A joke?

Yes. People are quite cavalier
with the definition of that word here.

Email, was it?

Does rather fit
Marty's MO, I'm afraid.

A joke? Yes.

Unfortunately for you,
one that gives you a motive.

Although, unfortunately for us,

it's the same motive
as everyone else.

Which is very inconvenient.

What motive? What
are you talking about?

I believe one of your
employees summed it up earlier -

Marty was an
A-triple-asterisk-hole.

This whole rota thing
of yours is ludicrous.

How does anyone
make head or tail of it?

You've got someone who's
supposed to be on G4 going to H1,

someone who was meant
to be at C3 going to F6,

and someone from A1 who's
gone so far down the alphabet,

I'm surprised their
zone's not in hieroglyphics.

Let me ask you something, is
there a single person that works

on this site who is ever
where they're supposed to be?

Doesn't look like it, sir, no.

They chop and swap at will.

No rhyme nor reason to it.

Madness.

Right, I've got it open.

I've gone right through it.

This guy had a lot
of email accounts,

all under different names.

I found your
deportation papers one.

And the fictitious Vegas job.

I then did a data-mine
on all his social media.

He had a lot of
accounts there, too,

but none in his own profile.

Some are men, some are women.

All the photo's have been
nicked from somewhere else

and all the names
have been made up.

Hmm, he was a catfish.

You, er... You do know what
a catfish is, don't you, sir?

I think you and everyone
else here knows full well

that I'm about to state
incorrectly that it's a type of fish.

Well, it's someone who pretends
to be somebody they're not.

I'm going to go through all
the accounts he's targeted

and see if any more of your
suspects are amongst them.

Thank you, Holly.

Guv, do you want to...?

Hmm?

Guv? Oh, er, yes.

So, the murder was
surprisingly well-planned...

..considering...

..but there was still a fair
amount of evidence left behind -

the re-wired generator,
the pool of water,

the loosened bolts.

And who's all this
evidence pointing to, sir?

I don't know yet.

So, how is it evidence?

Sergeant Finch, is there
something you'd like to get

off your chest?

Yes, please.

May I? Thank you.

OK, correct me
if I'm wrong, sir,

but presumably your theory is
that the killer set this "deathtrap"

up on the fourth storey,

and then manipulated
or coaxed the victim

into walking into it?

Yes, that's right. Ah!

Oh, no. Well done.

So, how did they guarantee

that nobody else
would walk into it first?

Our killer just wouldn't just
have to manipulate the victim -

they'd have to
manipulate the movements

of every single other
person on the site, too.

Is that even possible?

Of course it's possible.

It is possible, isn't it, guv?

I-It's possible, yes.

But presuming that
our killer was someone

of very high intelligence.

But they'd have to be a genius.

Guv?

Could it all just
be a coincidence?

Could what all just
be a coincidence?

Is it possible
that it really was...

..just an accident?

What? What are
you talking about?

You know it wasn't.

Guv?

You know it wasn't.

Light!

Light, light, light!

No, I'm not asking you to...

Off! Turn it off! Turn it off!

You can't just walk
in here, you know that.

The sign wasn't up.

Well, I thought that
you were out all day.

I was.

It's nearly five. Is it?!

Yes, it is.

Have you heard anything?

"Heard anything"? From Dad?

The article in the paper?

Oh, no, I doubt your father...
So you haven't heard anything?

I would've told you if I had.

Would you?

You never told me that he left.

I thought we'd had
this conversation.

I'm sensing that you
have had a bad day.

You're not the only one.

It will be OK.

Your Uncle John...

He is not my dad!

You might be able
to pretend that he is,

sitting there on the bed reading
the paper together, but I can't!

Go to your room. Come on, Mum.

I'm 15, you can't just... I
said, "Go to your room."

Hi.

Have you been crying?

No. Allergies.

What are you allergic to?

Life.

Yes. Me, too.

Fine. We'll worry about
you, then, shall we?

What if I can't
solve the cypher?

What if I actually
can't do any of this?

James is cleverer than
me. He always has been.

He... He's always better
than me at everything.

John, has something happened?

This building site murder.

I can't solve it.

It seemed planned
but also sloppy.

Evidence everywhere indicating
that it wasn't an accident.

But that was no mistake.

They just didn't care,

because they knew I
could never prove it.

So it's a game to them.

They're just laughing at me.

Like they always did.

"Always did"?

Yes, they're just a grown-up
version of all the kids

that would bully
me at the bus stop.

Nothing's changed.

John, what are
you trying to say?

I'm trying to say that I'm not
the smartest guy in the room.

I'm not even the smartest
guy on a building site.

So, who am I?

Well, a bit of a snob
judging by that last comment.

Apart from that, you are
someone completely untrained

who's just solved several
murders without batting an eye.

Perhaps I just got lucky.

You don't believe in luck!

You're the only person to have
ever found a four-leaf clover

and not even want it.

The four-leaf clover?

You remember that?

Vaguely.

I gave it to you in the end.

You were going to laminate
it and keep it forever.

Yes, well, I was a
sentimental idiot back then.

Don't say it like
that. You still are.

Thank you.

You're welcome.

Ahem!

Oh, it's just you.

What's up?

I think your mum
is cross with me.

Yeah, I think she's
cross with me, too.

I highly doubt that.

Don't touch that!

Sorry.

It's just, I'm in the
middle of a game.

Who with?

Oh, I see.

Not that we really
played it together.

He'd just sort of come in while
I was asleep and move a piece.

I'd wake up the next
day, move another.

Which side are you?

Black.

So your last move was
knight to queen one?

Yeah.

How did you know that?

It's difficult to
explain. It's...

It's a type of puzzle
called reverse chess.

I invented it actually.

You're presented with a
board in the middle of a game

but, instead of having to
work out what comes next,

you use maths,
probability and reason

to deduce what came before.

It didn't really catch on.

Nobody could ever solve them.

Your mother is
crying in the kitchen.

What?

Er...

And you've just left her there?

I'm not good at dealing
with that sort of thing.

Chess, on the other hand -
I've always been good at that.

One game I could
always beat your dad at.

That and Mouse Trap.

Is she crying because of me?

No.

Nor because of me.

She's crying because
she's frustrated, scared,

and the person she wants
to take it all out on isn't here.

I expect you can relate to that.

Mum?

Henry, please don't.

I can't go another round.

I'm sorry.

You have nothing
to be sorry for.

Neither do you.

Thank you.

Don't get used to it.

Right, then - let's start with one
central, and indisputable, fact.

This wasn't an accident.

This was a murder.

And an especially
ingenious one at that,

so... well done.

Marty Symes was led
to his death by a series

of supposedly
impromptu rota swaps

guaranteeing that he would be
the one to end up by the generator.

And the genius of it
all - and it was genius -

was that killer's manipulation
of all your movements

was tertiary at best.

Most of you were inadvertently
manipulating each other.

What? The killer, with an impressive
level of psychological insight,

accurately predicted who would
swap with who and in what order,

leaving his or her own
machinations hidden.

If it helps, I've prepared a
practical demonstration...

..I think.

Constable Evans, did you...?

Oh, er...

Yes, sir.

Excellent.

Now, if all this is starting
to sound like a game -

that's because,
in essence, it was.

You were all pawns.

And by a happy coincidence,

your impractical
grid system here

contains exactly the same
number of squares as...

What is this?

Well, it's a chess set, sir.

I had to go to the
garage. It's all they had.

They had loads of Connect Fours.

We'll keep that in mind for
any future cases, Constable.

My little girl's got that set.

Right, then. You
should like this.

It's a criminally
under-appreciated form of puzzle

known as reverse chess.

We start with the end-game
and we work backwards.

Marty Symes last
move was to F6 -

ie, the crime scene.

The rest of you, you
wound up in these spaces,

where not one of
you was meant to be.

Meaning that the game
had already been played

without any of you knowing.

So let's play it
again, shall we?

Backwards.

Marty found himself up in F6

because the riveter
in G5 had no power.

But he was only in G5

because he'd swapped
with Gary from C3.

And Gary only wound up in G5

because he'd swapped
with Ojay from F4.

Which should have left
Gary here with Stefan in G4,

except Ojay had asked
Stefan to swap with Zara in H1.

Which leads us to the only
move that really counts -

the first one.

The one that started
the sequence of events

that eventually led to Marty
heading off to the pneumatic riveter,

a pneumatic riveter that was,
itself, powered by a generator

on the fourth storey.

Or rather, in this instance,
not being powered by it.

Which of course was further
manipulation by the killer,

designed to move their
target one storey higher

to what my colleagues colourfully
referred to as a "deathtrap".

A generator that had
been deliberately re-wired,

railing bolts that had been
surreptitiously loosened

and an 18-litre bottle of
water that had been poured out

around the base of the generator

and then disposed of
down the nearby chute.

And the rest, as
they say, is tragedy.

Ah!

And all from just one move.

The opening gambit.

Yours.

Wait, what?

You don't think that I had
anything to do with this?

Of course not. You were just
the first piece to move, that's all.

But it wasn't your
hand that moved it.

Was it?

You were meant to be in H1.

You did swap with me.

Insisted on it, I would wager.

So...

Look, I ain't going to pretend
like I followed a word of that, mate.

But what I am going
to ask is why the hell

I'd want to kill Marty?

Quite why anybody ever wants
to kill anyone is a mystery to me.

I've certainly never wanted to.

But since you ask, I'm going
to go with pride and arrogance.

I do believe that
you took the "joke"

of the lottery
win in your stride,

even if you embarrassed
yourself slightly

by proposing to your
girlfriend as a result.

Almost proposing
to my girlfriend.

No, actually proposing.

Our computer woman
has seen the messages.

I was wondering, through -

when exactly did you discover
that you never even had a girlfriend?

That it had just
been Marty all along?

We've had all the IPs traced.

We know you were one
of Marty's catfish victims.

Even though you
were using a fake profile

and photo yourself.

Yes, ironically, you thought
you were catfishing "her".

In fairness, making the
joke a lot more layered

than I gave it credit for.

OK, well, if you must know,

I caught a glimpse of his
phone on a break, saw the profile.

So, what? He was pranking
me while I was pranking him.

It's not a reason
to murder, is it?

Not for a normal person, no.

But you're not a
normal person, are you?

You're a man of enviable
intellect who hides it all

behind spitting and
saying "mate" a lot.

A man who couldn't bare
to be beaten by someone

so much stupider than him.

That's it?

That's my motive?

That's the motive of
a complete sociopath.

Yes. It is.

Right, you going to
bring this little chess set

to trial with you, are you?

Oh, no, we've got some actual
real evidence to go along with it.

The water bottle that you
disposed of down the chute

was tested for DNA.

Sergeant Finch got the
results back this morning -

didn't you, Sergeant?

Yes, sir. It's a match.

All right. What was that, then?

The bottle I took from that
drinks dispenser over there?

The empty one that I
chucked in the skip?

From the fourth
storey, via the chute.

Nah, mate - from the
ground, via my hands.

Never even been
up to F6 - not once.

Your move.

My move.

Yes.

Well, come on, then!

Right, then.

Dispose of this
for me, will you?

You don't really expect to be able
to move a two-tonne skip, do you?

I thought I'd give it a go.

Congratulations, Detective.

Thank you.

I appreciate that.

Checkmate.

I believe this is yours.

I signed it for you.

Constable.

Right.

Er, that's not the
foreman, though, is it?

What? Oh, no, it's just...

It was supposed to be my turn.

Gary Jennings, I'm arresting
you on suspicion of murder.

You do not have to say anything,

but it may harm your
defence if you do not mention,

when questioned, something
that you later rely on in court.

Yes, sir.

Yes, sir.

Signed confession. Case closed.

It was DCI Taylor.

I can assure you that's
no longer an issue.

Yes, sir.

What have you got there, then?

Nothing.

You know, it's
the craziest thing.

I've been doing a security
sweep on all our systems,

and do you know what I've found?

Chief Constable Ziegler

has been accessing a lot of
files lately from your computer,

even on the days
he's not been there.

So, how do you
suppose he did that?

Don't worry, I've
wiped the system.

Why would you do that?

I don't know.

But I won't do it again.

Hello.

Oh, dear. What's the matter?

The computer woman
knows what I've been doing.

What? Using Ziegler's log-in,

accessing files I shouldn't be.

But she's covered it up,

wiped it all from the computers.

So, what does that mean?

Is she a goodie or a baddie?

I don't know.

But I'm going to find out.

What's all that?

Ah, it's for the cypher.

I've already made a start.

I'm going through
it all page by page,

book by book, night
after night if I have to -

no matter how long it takes.

You haven't given up, then?

Of course not.

Why would I?

I'm really good at this.
Don't you read the paper?

Right, speaking of homework...

Good lad.

Homework, my arse.

Do you fancy taking an hour off?

We could watch a
film. You can choose?

I-I'm all right, thanks. I...

Hello?

What do you think
you're playing at?!

I'm not sure?

I saw you in the paper!

Why are you back there?

I mean, what the hell do
you think you're doing?!

James?

I'm sorry, it's a
really bad line.

I...

Who is this?

Come in.

Oh, James just got
a funny phone call

from a funny phone number.

Who? Who was it? Was it him?

No, it was some man.
Well, what did he s...?

Sorry, what are you doing?

Well, you're in your,
you know, nightie.

I don't...

Why don't I get up, and you
go and make us both a coffee?

What's going on? What's
happening? Somebody's called?

Oh, no. It wasn't Dad.

I'm sure it's nothing
to worry about.

You go back to bed.

John, you'd better
make that three coffees!

Ah, there you
are, Guv. Let's go.

Go where? Back to school.

Looks like a suicide.

There's even a note.
Head of English, eh?

Two double negatives,
no apostrophes.

James' phone has been cracked.

Someone's tampered
with the software.

Ah, Mr Todd?

It's Taylor, Sir.

Yes! I remember the Taylor boys!

Jacob and... Joshua.

No, sir, James and John.

That's right!

The nutty professor.

I wouldn't listen to
much of what he says.

I do hate bullies.

Are you police? Detectives, yes.

What, both of you?

This week was supposed
to be a new beginning.

Oh, I've got it. It's
an address in Wales.

You're not going to
go, are you, Mum?

How did you... get my number?

Lucy? What are you doing here?
