how do you do? thank you, woburn. do sit down, won't you? let me say at once, we're shocked. that you son was taken from you in marrakesh and deeply sympathetic. we might find him. quite soon, indeed, if we work together. louis bernard was sent to marrakesh by the french at our request to check up on an assassination plot -- here, in london. a good agent keeps on staking his life. he doesn't always win. bernard reckoned you were a man to trust. he relied on you, to come to us. those people kidnapped your boy -- in order to keep your mouth shut. that's right, isn't it? then why didn't you go straight to your consulate in casablanca? why did you come to london? you're convinced that these people brought your son to london. you're convinced you can find him -- off your own bat. you can't. it's impossible. but with the help we can give you, there's a chance. a really good chance. anything you tell me will be in the most absolute confidence. your son is the trump card these people hold. he's perfectly safe -- for the moment. no, mrs. mckenna. if they consider the boy a nuisance, afterwards -- i'm afraid -- it's exactly what i'm trying to do -- frighten you. i'm trying to prevent a man being murdered here, in london. if you don't tell me all you know, you become an accessory before the fact of murder. in english law, you become just short of murderers yourselves. then you tell me. and what did you write down on a piece of paper? i have a son of my own. i don't know what i'd do. a phone call for you, mrs. mckenna. put the call through here, please. mrs. mckenna. it was a london telephone exchange. you may change your minds. if you do, this number will reach me. i'll report to you fully at the embassy, your excellency. in the meantime. we can talk if you'll come in here. so you both know the time and place all along. an odd coincidence -- both of you turning up here. i beg your pardon. i'll see her later. please tell me everything, now. everything. there's still plenty of room for hope, mrs. mckenna. trying to liquidate one of their own big-shots. i wish they'd stick to their usual custom, and do it in their own country. buchanan speaking. right. bye. the draytons are at the embassy. we have ways of finding out -- from the inside. you're probably right. but we can do nothing. every embassy in a foreign country has extra-territorial rights. as far as we're concerned, this embassy stands on foreign soil. we could have the foreign office serve a writ on the ambassador. you know, i'm not responsible for the complications of international law. if only we had positive proof that the boy really is in there.
