Henri Magritte was a man possessed by one desire: to find the informer who had betrayed his brother. Robert's death at the hands of the Gestapo had so affected him that he had turned his back on his family and friends in Paris, retreating into bitter cynicism. During the seven years following the war, Henri had drifted aimlessly — until Marcelle Duvernoy reappeared in his life. She was even more beautiful than when she had been his mistress during the days of the Resistance. Although she was now married to a wealthy American, some of the magic of their love remained. Suddenly Henri's friend Commissaire Genet of the Paris police hit upon evidence pointing to the identity of a ring of wartime collaborators. Feverishly Henri began working side by side with the police, determined to find the man who had been at the core of the conspiracy. Some of the suspects wept under interrogation. Others boasted freely that they had been responsible for the execution of many Resistance agents. But all said they knew the Gestapo contact only as a voice on the telephone — a man known as "Albert." The telephone number? None could remember. Then it happened. Henri remembered a photograph — remembered it almost subconsciously, as one remembers a face form childhood. And Albert was forced to take an irrevocable step.
