Farewell dinner for a spy

1949: William Catesby returns to London in disgrace, accused of murdering a 'double-dipper' the Americans believed to be one of their own. His left-wing sympathies have him singled out as a traitor. Henry Bone throws him a lifeline, sending him to Marseille, ostensibly to report on dockers' strikes and keep tabs on the errant wife of a British diplomat. But there's a catch. For his cover story, he's demobbed from the service and tricked out as writer researching a book on the Resistance.
