Well, Seager promised he would never know. 379 00:24:24,685 --> 00:24:29,324 Then this letter turned up from the prison a couple of months ago 380 00:24:29,325 --> 00:24:31,205 saying that he'd changed his tune. 381 00:24:31,206 --> 00:24:33,964 Suddenly it was all morally wrong. 382 00:24:33,965 --> 00:24:37,485 He was giving me ten weeks to talk to Adam myself before he blew the whistle. 383 00:24:37,486 --> 00:24:42,045 Do you still have this letter? Adam made me show it to him. 384 00:24:42,565 --> 00:24:45,203 It was only then that he told me that the man was dead. 385 00:24:45,204 --> 00:24:47,765 So I could have got away with never telling him at all. 386 00:24:48,405 --> 00:24:52,523 Our last conversation didn't... have to be me humiliating my son. 387 00:24:52,524 --> 00:24:54,805 It could have been me telling him that... 388 00:24:58,045 --> 00:25:00,003 ..that I love every bone of him 389 00:25:00,004 --> 00:25:02,725 if he never passed a single exam in his entire life. 390 00:25:06,725 --> 00:25:08,285 Sorry. 391 00:25:12,445 --> 00:25:14,445 I'll get that letter. 392 00:25:17,605 --> 00:25:20,285 I'm sorry, what did you say your name was again? 393 00:25:21,605 --> 00:25:24,044 DS Hatha... Erm... James. 394 00:25:24,045 --> 00:25:27,963 You're the one who found him. They said that you tried to help. 395 00:25:27,964 --> 00:25:30,085 I didn't help him. But you tried. 396 00:25:30,086 --> 00:25:33,045 Thank you. Thank you, James. 397 00:26:23,805 --> 00:26:25,805 DI Lewis, please. 398 00:26:27,605 --> 00:26:31,245 OK. No, no. No message. 399 00:26:42,325 --> 00:26:44,925 Well, I guess it's all there, isn't it? 400 00:26:49,525 --> 00:26:52,443 I just wanted something that was mine, you know? 401 00:26:52,444 --> 00:26:56,125 I got fed up of being the other half of the great biochemist. 402 00:26:56,126 --> 00:27:00,964 So you set up Oxbridge Edge? It's a legitimate coaching business. 403 00:27:00,965 --> 00:27:04,445 There were only a handful of occasions when it turned into anything more. 404 00:27:04,446 --> 00:27:06,925 And how did those occasions work? 405 00:27:09,165 --> 00:27:11,644 Sometimes, with particular families, 406 00:27:11,645 --> 00:27:14,045 you could tell they would do anything. 407 00:27:15,245 --> 00:27:17,683 I'd scope them out, and if they were receptive, 408 00:27:17,684 --> 00:27:19,565 I'd put them in touch with Seager. 409 00:27:20,325 --> 00:27:22,444 It was a huge risk, obviously. 410 00:27:22,445 --> 00:27:26,005 The University would have come down on us like a ton of bricks. 411 00:27:26,006 --> 00:27:28,284 But if we could convince Yardley 412 00:27:28,285 --> 00:27:31,405 that it was watertight, he'd give us ten per cent. 413 00:27:32,005 --> 00:27:34,645 Did you receive one of these letters from Seager? 414 00:27:35,725 --> 00:27:38,843 A couple of months ago. And what would that have done to you? 415 00:27:38,844 --> 00:27:42,325 Look, I see where you're going with this, but I didn't kill him. 416 00:27:45,445 --> 00:27:48,564 Hi. That was pretty horrible. 417 00:27:48,565 --> 00:27:53,005 I don't know why she wanted to go back there so soon when it's... 418 00:27:53,006 --> 00:27:55,765 Is everything OK? Carl? 419 00:27:56,965 --> 00:28:00,485 Well, the college needed money. That was a way to get it. 420 00:28:00,486 --> 00:28:03,844 I think it's the only thing 421 00:28:03,845 --> 00:28:07,805 that Professor Seager and I ever saw eye to eye on in 30 years. 422 00:28:08,845 --> 00:28:10,683 But you didn't see eye to eye anymore. 423 00:28:10,684 --> 00:28:12,803 Seager was going to confess, you knew that. 424 00:28:12,804 --> 00:28:14,603 He was going to end your career. 425 00:28:14,604 --> 00:28:17,925 I took on this Mastership with a very public promise 426 00:28:17,926 --> 00:28:20,284 to turn Benison's fortunes around. 427 00:28:20,285 --> 00:28:22,525 I staked my reputation on it. 428 00:28:24,485 --> 00:28:26,485 But I've failed. 429 00:28:26,885 --> 00:28:30,285 We reached the point of financial no-return six months ago. 430 00:28:31,285 --> 00:28:36,445 The college will be forced to merge, leaving its Master without a future. 431 00:28:37,245 --> 00:28:39,004 So there's really nothing 432 00:28:39,005 --> 00:28:41,605 that Richard's spiritual cleansing could have done 433 00:28:41,606 --> 00:28:44,325 to make things any worse. 434 00:28:58,045 --> 00:29:01,525 It's me. Call me as soon as you get this. 435 00:29:02,045 --> 00:29:04,045 I need to see you. 436 00:29:09,405 --> 00:29:13,244 Carl Drew, Yardley and Mr Tibitt, Adam's dad. 437 00:29:13,245 --> 00:29:15,763 Plus any other parents who received the same letter. 438 00:29:15,764 --> 00:29:18,603 Any one of them could have killed Seager to stop him talking. 439 00:29:18,604 --> 00:29:20,965 True. But... how does that connect to Soo-Min? 440 00:29:21,805 --> 00:29:24,003 Maybe it doesn't. You don't believe that. 441 00:29:24,004 --> 00:29:27,003 Anyway, what about his blood on her suitcase? 442 00:29:27,004 --> 00:29:30,803 So he was her tutor, he carried her suitcase once. It doesn't prove he killed her. 443 00:29:30,804 --> 00:29:33,325 Or that Seager was killed because of Soo-Min. 444 00:29:39,125 --> 00:29:42,483 Maybe we started in the wrong place, starting with Seager. 445 00:29:42,484 --> 00:29:44,485 The answer has to be with Soo-Min. 446 00:29:46,085 --> 00:29:47,763 Come on. Where are we going? 447 00:29:47,764 --> 00:29:51,885 Back to the station, where we've got an entire suitcase full of evidence. 448 00:29:53,045 --> 00:29:55,645 You didn't have any plans for tonight, did you? 449 00:30:16,965 --> 00:30:20,365 What exactly is it we're looking for? No idea. 450 00:30:21,285 --> 00:30:24,323 But we're going to look at every photo, every book, 451 00:30:24,324 --> 00:30:26,965 every page of every folder until we find it. 452 00:30:49,565 --> 00:30:51,565 Oh, my God! 453 00:30:59,703 --> 00:31:03,383 Uniform have started a door-to-door.

Not yet. Someone's done a good job. 462 00:31:26,089 --> 00:31:28,089 But one of the boys noticed this. 463 00:31:30,769 --> 00:31:32,889 The missing one doesn't seem to be here. 464 00:31:32,890 --> 00:31:35,929 Ah, that's not good news. 465 00:31:37,609 --> 00:31:39,448 I'm not sure I follow. 466 00:31:39,449 --> 00:31:42,447 Well, Seager's murder seemed to be carefully planned - 467 00:31:42,448 --> 00:31:45,607 the pay-as-you-go phone, car keys stolen in advance. 468 00:31:45,608 --> 00:31:47,487 But if that's the murder weapon, 469 00:31:47,488 --> 00:31:51,047 then whoever stabbed his wife didn't even think to bring his own knife. 470 00:31:51,048 --> 00:31:53,689 And if it's the same person, they're getting desperate. 471 00:31:54,129 --> 00:31:55,887 According to the calendar in there, 472 00:31:55,888 --> 00:31:57,967 she kept a regular appointment with her GP. 473 00:31:57,968 --> 00:32:00,567 The next one was today at three so I thought I might go. 474 00:32:00,568 --> 00:32:03,127 Yeah, why not?

Well, exactly. 511 00:34:09,444 --> 00:34:13,083 If her killer was feeding her addiction, then he was helping her drug herself. 512 00:34:13,084 --> 00:34:15,803 Maybe Martha figured this out and confronted her supplier. 513 00:34:15,804 --> 00:34:17,363 Right. You need to find the pills. 514 00:34:17,364 --> 00:34:19,243 If we can prove that Carl's the one 515 00:34:19,244 --> 00:34:21,565 that supplied Martha, I reckon we've got him. 516 00:34:22,725 --> 00:34:25,485 Dark matter.
