Winding up the tense story begun in Berlin Game and continued in Mexico Set, Deighton's new thriller follows British intelligence agent Bernard Samson as he careens between troubled spots in Berlin and London. Bernard's recent triumph is persuading the KGB's renowned spy Erich Stennis to defect to England but, since Samson's wife Fiona has gone over to the Russians, he isn't entirely trusted by his colleagues. Now suspicions that another mole has been planted among the operatives in London exacerbate Samson's fears, mostly for his small children, if he is accused. Determined to protect himself from his own fellow workers and the wily plots of Fiona and the KGB, Samson plunges into harrowing situations, climaxing in a bloody battle which both sides claim they've won. Actually, as Samson reveals, everybody loses in the deadly game of espionage.
