it's beginning to feel like an investigation being obstructed. i've got better things to do than that. what are you hiding? do i need to remind you how much you can trust me? between you and me, i'm in a bit of a hole. we were tipped off that there was a mole in the foreign office, passing information on to the soviets and i was asked to bring her in. i was given her name, evelyn green, and her address on a pink chit, so i picked her up, passed her on. only to discover that we'd got the wrong woman. a completely innocent evelyn green. i don't understand it. i was given her name and her address on a pink chit. so it was only partly my fault. meyerson, he's going to want a scapegoat and it looks like it's going to be me. when did you find out you'd made the mistake? when the real evelyn green turned up in east berlin.

where did the pink chit come from? barton hall. between you and me, i think it will help if you let me take a look at these files. all right. thank you. these only go back to '38. how far do you want to go back? well, how about the beginning? mrs. green, hello! mum!

thank you. thank you. thank you. wish me luck. good luck. got your speech? yep. remember not to answer the door to anyone apart from us. glenvil. indeed. foyle. we've had a security breach. i'm afraid you'll have to leave immediately. can't wait-- one or two questions before i do. you're not listening. well, technically, neither are you. this isn't a y station, it's an interrogation center in which at least one person has been murdered, so there are one or two questions.

we're developing new interrogation techniques. the intelligence that we extract is passed directly to mi5. you see, violence can often result in the wrong answers-- a good interrogator seeks the truth without resorting to brutality. a technique not applied in palenko's case, it would seem. palenko was rounded up in a general sweep. he had no identification. we suspected him of being a russian spy and went to work on him. he cracked and tried to take his own life. the man ross saw following palenko to the hospital the night he died, would that have been you, by any chance? (buzzer rings)

you don't have the authority to question me or anyone else at barton hall. sir? escort mr. foyle out. it is your duty to leave here and never speak of this again. well, our ideas of duty obviously differ quite considerably. good afternoon, sir. excuse me, would you mind telling me who you voted for? no. how's it... good afternoon. how's it looking? it's close. but this helped. please tell me this wasn't you. excuse me, do you mind telling me who you voted for, please? mrs. ross, i'm not at all sure how much comfort this will be

to you, but your husband didn't kill himself. he didn't? no. when he returned home after the car accident, you mentioned he was eager to check some blood samples. am i right? yes. were these samples taken at the accident? i believe so, yes. where might we find these? please. this must have been what he was last working on. yes, this is the blood sample. and this must be the result. what does that say? someone suffering from tick-borne encephalitis. fatal without treatment. i saw a lot of it in the camp.

sir? yes. galt's file is on your desk. thank you. i'd like james mcdonald's as well. would that be a problem? not at all. good, thank you. absolutely nothing to do with us. too much of a coincidence to ignore. the man's given carte blanche to wander all over the place, and within 48 hours there's a major security breach. if that's the case, it was done without the knowledge or authorization of this office. what's more, he turned up again this morning. nerve of the man. and the wrong girl, why haven't i been told about that? i've only just heard about her myself. you're not suggesting that foyle broke in? of course not! then who? unidentified, but you can bet your boots he's connected to foyle. well, how much does foyle know about the place? more than he should. and who's fault is that? well, i didn't invite the blighter in! all right, i accept there may have been mistakes. i take my share of the blame, sir. charlotte: sir? i asked not to be disturbed! mr. foyle...

foyle: i do beg your pardon. sorry to interrupt. colonel? pierce: thank you, charlotte. foyle, come in, you do have some questions to answer. well, that'll make a change. the break-in at barton hall. how much do you know about it? oh, only what i heard this morning. a girl's gone missing. another one? this is important, man. and we have reason to believe you know where she is. she's in possession of confidential information. if it gets out, our entire work could be fatally undermined. it already has been. explain yourself. at some point recently, was mcdonald absent from the unit? i said explain yourself. i'm sick and tired of your damn questions. occupational hazard, colonel. would that be correct? yes, i gave him 48 hours leave after the russian was interrogated. why? and were you both present at that interrogation? yes, mcdonald translated.

well, you won't be pleased to learn that he's been responsible for undermining your unit for some considerable time. james mcdonald? the russian even made a dying attempt to warn you... tin eye. this is mcdonald's file. does no one ever read these things? what's the news? it's neck and neck according to my own poll. not much we can do now. well, that's good.

colonel galt. mr. foyle. do you mind if i don't get up? i'm not feeling too dandy at the moment. can't seem to shake this bug off. foyle: well, i'm sorry to have to tell you, major mcdonald, but you're unlikely to feel dandy ever again. get an ambulance. i don't understand. i do. you have a condition called encephalitis contracted through your tick bite. it attacks the central nervous system and is fatal without treatment.

your infection has gone untreated because the person who made the diagnosis and the only person in the position to be able to treat you is the person you murdered. dr. ian ross. you killed him in the belief that he'd recognized you at the car accident; he hadn't. what he did recognize was the condition, as a result of the blood samples he took and that the condition cannot be contracted in this country. it is common, however, in parts of europe-- east berlin, for example-- which is where you were infected while escorting evelyn green into the russian zone. you two were at cambridge together, weren't you? well, i have all the time in the world. (breathing heavily) we met at the debating society.

i was a postgraduate; she was younger. highly intelligent and beautiful. i'd never seen anyone so beautiful. we were kindred spirits. we were both sickened by the class system. the snobbery, the hypocrisy, the greed. we've been lovers and comrades ever since. palenko deserved to die. he betrayed the cause. now we're getting somewhere. find out who she is. (both speaking russian)

...evelyn green. evelyn green? where? (speaking russian) foreign office. i don't trust him. he'll say anything. he could be a trojan horse for all we know. i agree. all the same, we should inform mi5 about this woman in the foreign office. shouldn't we verify his story before we accuse someone of being a spy? we have no choice. we need to pick her up immediately. do it. sir? something the matter? as a matter of fact there is, sir. it's my sister's husband, there's been a dreadful accident. she's not coping very well. i was wondering if i... palenko's not going anywhere.

how much time do you need? 48 hours. 48 hours, then. thank you, sir. mcdonald: i gave mi5 details of another evelyn green at a different address. then i made a phone call. evelyn greene (on phone): kensington 3487. is your bag packed? evelyn? yes. get out now. meet me at paddington station. evelyn had an inter zone id card. we'd prepared one for just such an event. what about palenko? i was ordered to return and silence him.

(discordant music playing) (yelling in russian) mcdonald: i knew that he couldn't speak english, but i had to be sure. i chased him to the hospital. how he ever managed to get there... i heard ross pronounce him dead...

he's gone. mcdonald: i thought he might have seen me, might have been able to identify me. all my life i've believed that communism will prevail. one state, one mind, all equal. i've sacrificed everything for the cause. everything. now i won't live to see it. but it will come. contemptible!

(gunshot) man (on intercom): thurston, conservative: 6,322. watt: liberal, 5,251. wainwright: labour, 6,448. yes! (cheering and applause) sam, what are you doing?

this. sam, i've got to make a speech. so do i. adam wainwright. you're going to be the best member of parliament peckham has ever seen. i'm so bloody proud of you. i couldn't have done it without you. that's just not true. adam-- sorry-- speech. come on. what's happened to the girl? back with her family. will she talk? she'd sooner forget the whole thing, i think. can't say i blame her. the man who got her out, i take it that was your doing. he certainly proved himself quite useful. maybe we should encourage him to apply. i'll see what i can do. take a seat, mr. foyle. i can't close barton hall, if that's what you're thinking.

it doesn't bother you how the intelligence that arrives on your desk is obtained? no, of course it does. but if you think the soviets aren't using the same-- or worse-- methods, you're wrong. well, i'm aware of what they do; it's what we do that's the issue. but it's intelligence that has saved many of our agents' lives. i have to see both sides of the coin. that's my job. but listen to me. pierce is first class, but you have something i need, and i don't mean your inability to toe the line. it's just that in this rather nasty little war we seem to be fighting, i'd like to think that i have you on my side. and it might just be that working together, we could do some good. we could start with mrs. ross, perhaps. yes?

next time on masterpiece mystery!... meyerson: carl strasser, nazi. he's been an extremely valuable intelligence asset. we can't afford to lose him. the greater good? exactly, foyle. we both want the same thing. and what's that? man: we want him dead. (gunshots, screaming) we can't do this. this is getting out of hand. they could prosecute you for this; you must be careful. how many times do you need to be told? next time on masterpiece mystery! national funding for masterpiece is provided by... t of historic cities and landscapes on a river, you see things differently. you get close to iconic landmarks, to local life,

>> appraiser: well, what a stunning portrait of a beautiful lady. can i, can i see a resemblance here? i think i can, which is lovely. >> woman: yes, it is a picture of me. >> appraiser: a picture of you. and how old were you when this was... >> woman: i was 22. >> appraiser: 22. and, of course, it's by the great, great painter stanley spencer. that is fantastic. how did your family or how did you know stanley spencer? >> woman: well, we lived in cookham, which is where stanley spencer lives, and my father was his doctor. >> appraiser: gosh. >> woman: and he got to know him very well. he was keen on art and things. so we used to go up there and have a look at his paintings when they were being done. >> appraiser: ah, what an amazing story. what sort of man was stanley spencer like? >> woman: he was a chatterbox, never stopped talking.

and if he'd come to a cocktail party or something like that, the only way you could get him to go home was to take him home. >> appraiser: really. (laughter) but was he good company? >> woman: oh yes. >> appraiser: fascinating. and i note -- i mean, it's nicely signed, your portrait, stanley spencer, october 1959. and of course he died in 1959. >> woman: well, he was dying of cancer and my father said to my mother, "he's not eating. let's get him." so he came to our house, and to keep him occupied, he'd draw me, and we gave him some food. then soon after that he went into the hospital where he died. >> appraiser: so sad because he was sort of -- 68, i think, when he died. so a young man. >> woman: yes, really, yes. >> appraiser: and -- i mean, he really lived in cookham all his life, didn't he? i mean, it was this sort of paradise for him. >> woman: yes. >> appraiser: and he did a lot of biblical subjects, but set in cookham. >> woman: that's right. >> appraiser: but he's an absolute genius. and i think you can see by this

portrait at the end of his life how wonderful it is. the attention to detail is phenomenal. he has that almost pre-raphaelite exactness. i think he's majestic. now, have you ever had this valued? >> woman: no. >> appraiser: oh dear. know what? -- i mean, they are just so -- i mean, people just love stanley spencer. they love his work. i mean, this drawing's big. it's beautiful. lovely sitter. 10 to 15,000 pounds. >> woman: [gasps] wow! i think we'll take it to the gallery in cookham to look after. >> appraiser: not bad for two days work. >> woman: thank you very much. >> appraiser: thank you.
