Joker in the Pack

British Cabinet Minister David Raffo asks to see the file the British Secret Service MI5 kept on him when he was a student radical in late 1960s Britain. Immediately he receives threatening emails signed by The Joker. The closer he gets to unmasking the identities of the informers who spied on him in the past, the more threatening the emails from The Joker become. He realises there is a traitor in MI5 who is desperate not to be flushed out. The minister's flat is broken into, an MI5 agent is murdered and Raffo fears for the safety of his research assistant, Anna Farrow. The answer must lie in the then Czechoslovakia where Raffo led a British student delegation shortly before the Russian invasion to snuff out the Prague Spring. The dramatic end game, revealing cynical CIA involvement, is played out in the beautiful but dangerous city of Prague with tragic consequences for the informers and the agents.
