It was like, she was his wife, so I hated her. 208 00:17:17,940 --> 00:17:19,980 But it also felt like she understood. 209 00:17:20,700 --> 00:17:23,300 Like I could say things to her that I couldn't say to my mum. 210 00:17:24,340 --> 00:17:26,820 So tell me about last night. 211 00:17:26,820 --> 00:17:29,700 I finally realised it was all an act. 212 00:17:29,700 --> 00:17:33,380 She was just pretending to be nice so I'd forgive her husband. 213 00:17:33,380 --> 00:17:35,700 She said that you were really upset when you left. 214 00:17:35,700 --> 00:17:39,300 Where did you go after?

Come on. 229 00:18:27,700 --> 00:18:32,020 My old granny used to pay me in giant chocolate biscuits for mowing her lawn. 230 00:18:32,020 --> 00:18:34,820 Sounds like an excellent trade-off. It wasn't bad. 231 00:18:40,340 --> 00:18:43,060 I stayed with her almost every year. 232 00:18:43,060 --> 00:18:44,980 Little bungalow out at Whitley Bay. 233 00:18:45,540 --> 00:18:48,580 Do you know when I last saw my grandson? 234 00:18:48,580 --> 00:18:51,380 Christmas.

Turns out they're expensive. 284 00:21:44,900 --> 00:21:47,420 Apparently ours is on the verge of collapse. 285 00:21:47,420 --> 00:21:49,060 I'm sorry to hear that. 286 00:21:49,060 --> 00:21:50,900 Well, how can I help? 287 00:21:50,900 --> 00:21:54,940 Did Professor Seager have any enemies that you were aware of? 288 00:21:54,940 --> 00:21:57,620 The usual intellectual squabbles, 289 00:21:57,620 --> 00:22:00,500 but nothing serious that I can recall. 290 00:22:00,500 --> 00:22:02,780 And what was the plan for after his release? 291 00:22:02,780 --> 00:22:05,580 Was he coming back to work? Well, that was a difficult one. 292 00:22:05,580 --> 00:22:09,140 Richard had a brilliant scientific mind. Truly brilliant. 293 00:22:09,140 --> 00:22:13,420 But with fellowship comes moral responsibilities. 294 00:22:13,420 --> 00:22:18,140 We held a ballot, and the majority vote was to revoke his fellowship 295 00:22:18,140 --> 00:22:21,020 and promote Stella to his Chair of the Chemistry role. 296 00:22:21,020 --> 00:22:24,300 Stella? Doctor Stella Drew, Richard's protegee. 297 00:22:24,300 --> 00:22:26,460 I think she's the best person you can speak to. 298 00:22:26,460 --> 00:22:28,220 Knew him much better than I did. 299 00:22:28,220 --> 00:22:30,260 Any idea where I might find her? 300 00:22:30,260 --> 00:22:34,340 You could try her rooms.

I'm Stella's husband. 307 00:22:52,540 --> 00:22:55,700 That's the last time I let my Year Nines loose with the iodine. 308 00:22:55,700 --> 00:22:57,540 Please come in. 309 00:22:58,620 --> 00:23:00,780 So you knew Professor Seager? 310 00:23:01,900 --> 00:23:04,420 He taught me and Stella when we were undergrads here. 311 00:23:04,420 --> 00:23:07,340 Stella decided to stay on and I was kind of stuck with him. 312 00:23:07,340 --> 00:23:10,180 Not his biggest fan, then? Oh, he wasn't that bad. 313 00:23:10,180 --> 00:23:12,660 Just a little bit, you know... Oxford. 314 00:23:14,580 --> 00:23:17,460 If you weren't ridiculously gifted like Stell, 315 00:23:17,460 --> 00:23:19,780 you basically were invisible to him. 316 00:23:19,780 --> 00:23:23,220 How well did you know his wife? Far too well. 317 00:23:23,220 --> 00:23:26,820 She's Stella's best friend. One of mine, too. 318 00:23:26,820 --> 00:23:30,380 We've been treated to the ongoing saga of their marriage for years. 319 00:23:30,380 --> 00:23:33,220 The saga? It's been dragging on forever. 320 00:23:33,220 --> 00:23:36,620 Richard filed for divorce a couple of years ago, 321 00:23:36,620 --> 00:23:40,220 Martha was fighting it and he never quite moved out. 322 00:23:40,220 --> 00:23:43,620 I think she was almost glad when he was sent to prison. 323 00:23:44,820 --> 00:23:47,420 At least it meant he wouldn't leave her. 324 00:23:47,420 --> 00:23:49,060 Stella knows more about it. 325 00:23:50,140 --> 00:23:52,100 Greenaway Labs, science park. 326 00:23:53,700 --> 00:23:55,620 She'll be there till late. 327 00:23:58,540 --> 00:24:00,660 James? See what you can find out 328 00:24:00,660 --> 00:24:04,180 about a Doctor Stella Drew of Benison College, 329 00:24:04,180 --> 00:24:07,700 then meet me in the science park in about an hour. 330 00:24:07,700 --> 00:24:10,580 Can we make it more like three? I've got a bit sidetracked. 331 00:24:10,580 --> 00:24:13,740 Oh? What by? Stapleton did some digging, 332 00:24:13,740 --> 00:24:16,340 came up with years of debate in the scientific press 333 00:24:16,340 --> 00:24:19,580 between Seager and the Master of Benison College - Graham Yardley. 334 00:24:19,580 --> 00:24:22,220 I just met him. A bit cagey. 335 00:24:22,220 --> 00:24:24,380 Well, he's waged war on Seager since the '80s, 336 00:24:24,380 --> 00:24:27,860 arguing that his Christian teaching should be banned from universities. 337 00:24:27,860 --> 00:24:31,020 Really. I don't think he got around to telling me that. 338 00:24:58,110 --> 00:25:00,310 How's that thinking going? 339 00:25:00,310 --> 00:25:02,630 Have you fixed up a meeting with Innocent yet? 340 00:25:02,630 --> 00:25:06,230 No. But I managed to get in touch with Seager's prison officer. 341 00:25:06,230 --> 00:25:08,430 Changing the subject. OK. 342 00:25:08,430 --> 00:25:12,750 Apparently Martha forgot to tell us that he was a raging alcoholic 343 00:25:12,750 --> 00:25:14,910 and had been for a decade. 344 00:25:14,910 --> 00:25:17,550 He had a drink problem? Are they sure about that? 345 00:25:17,550 --> 00:25:19,270 Everyone in the prison says the same. 346 00:25:19,270 --> 00:25:22,390 He spent his days praying, going to alcohol recovery meetings 347 00:25:22,390 --> 00:25:25,350 and talking about how to lead a better life when he got out. 348 00:25:25,350 --> 00:25:27,950 Visitors? Only Martha the entire year - 349 00:25:27,950 --> 00:25:30,830 with the exception of one visit 10 days ago from Adam Tibitt. 350 00:25:31,910 --> 00:25:35,030 Rachel's boyfriend. Interesting. 351 00:25:35,030 --> 00:25:36,790 Now, where are we? 352 00:25:36,790 --> 00:25:39,670 Greenaway Labs... I realised after you called, 353 00:25:39,670 --> 00:25:41,710 I've come across Stella Drew before. 354 00:25:41,710 --> 00:25:44,430 I heard her interviewed on Woman's Hour a few months ago. 355 00:25:44,430 --> 00:25:46,990 Woman's Hour?

You might have. 373 00:26:38,060 --> 00:26:39,860 Never mind. 374 00:26:39,860 --> 00:26:41,860 So let's get to the point.

If all the phones begin with extension 500 407 00:28:18,060 --> 00:28:19,980 there might be a voicemail on one of them. 408 00:28:19,980 --> 00:28:22,460 I could ask the university to grant me access. 409 00:28:22,460 --> 00:28:24,580 Are you proposing phone hacking, Sergeant? 410 00:28:24,580 --> 00:28:26,660 It's not phone hacking if you ask nicely. 411 00:28:26,660 --> 00:28:30,540 From the degree of hypostasis and the decreased fluid pressure behind the eyes, 412 00:28:30,540 --> 00:28:33,660 I'd put time of death at 2:00 or 3:00am. 413 00:28:34,660 --> 00:28:37,220 What?
