She wouldn't have any problem getting mercury. 9 00:00:25,800 --> 00:00:27,840 And she'd know what to do with it. 10 00:00:27,840 --> 00:00:30,920 They were letters - nothing else. I wanted to make him hurt. 11 00:00:30,920 --> 00:00:34,360 Mr Adomakoh is one of our brightest stars, all the way from New York. 12 00:00:34,360 --> 00:00:37,000 There wouldn't have been a breakthrough if not for me. 13 00:00:37,000 --> 00:00:39,720 If their research can make a difference when I'm gone... 14 00:00:39,720 --> 00:00:42,760 A legacy.

Anyway, he doesn't have to sack me. 62 00:05:25,160 --> 00:05:28,800 I'm a consultant. All he has to do is not renew my contract. 63 00:05:28,800 --> 00:05:33,280 Which will be very easy if I've been away for a while and people have forgotten I exist. 64 00:05:33,280 --> 00:05:35,440 Well, what am I meant to do?

You sent him a bomb. 578 00:37:09,280 --> 00:37:13,080 And your proof? The rings are well known. Anyone could've sent that card. 579 00:37:14,680 --> 00:37:16,720 Who said anything about a card? 580 00:37:24,880 --> 00:37:27,000 Adam wasn't the intended victim.

You had to shut him down. 591 00:38:00,160 --> 00:38:03,080 So you gave us the murderer, killed by his own bomb. 592 00:38:03,080 --> 00:38:05,160 Except he wasn't, was he? 593 00:38:05,160 --> 00:38:08,640 You strangled him, and then tried to frame him. 594 00:38:10,240 --> 00:38:11,440 David? 595 00:38:14,040 --> 00:38:15,960 Tell me they're wrong. 596 00:38:29,680 --> 00:38:32,480 Adam always said you used to bear grudges. 597 00:38:33,320 --> 00:38:36,200 Even as a kid - store it up, let it fester. 598 00:38:36,200 --> 00:38:38,160 That's nonsense.
