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.
