Our kind of traitor - John Le Carr

Britain is in the depths of recession. A left-leaning young Oxford academic and his barrister girlfriend take an off-peak holiday on the Caribbean island of Antigua. By seeming chance they bump into a Russian millionaire called Dima who owns a peninsula and a diamond-encrusted gold watch. He also has a tattoo on his right thumb, and wants a game of tennis.

What else he wants propels the young lovers on a tortuous journey through Paris to a safe house in the Swiss Alps, to the murkiest cloisters of the City of London and its unholy alliance with Britain's Intelligence Establishment.
