Britain is in the depths of recession. A left-leaning young Oxford academic & 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 & a diamond-encrusted gold watch. He also has a tattoo on his right thumb & 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 & its unholy alliance with Britain's Intelligence Establishment.
