Callan Season 3 Episode 3 The Same Trick Twice Over

Callan and Bishop are at the German border to exchange a KGB agent for two British agents. The exchange takes place, and the two British agents, Mallory and Surtees are to be debriefed.

However, Surtees proves to be a very difficult man who will not co-operate as he says he was blackmailed by British Intelligence to spy for them in the first place. He intends to write his memoirs and have them published. Hunter is extremely worried about the effect that this will have on the Section, and orders Callan to do something about it.

Callan doesn't want to harm Surtees and makes a few enquiries before committing himself. He enlists the aid of Lonely, who is working at Harry's Strip Bar as a lavatory attendant.
