‘One of our very best writers on France.’ Antony Beevor

After publishing an acclaimed biography of Jean Moulin, leader of the French Resistance, Patrick Marnham received an anonymous letter from a person who claimed to have worked for British Intelligence during the war. The ex-spy praised his book but insisted that he had missed the real ‘treasure’. The letter drew Marnham back to the early 1960s when he had been taught French by a mercurial woman – a former Resistance leader, whose SOE network was broken on the same day that Moulin was captured and who endured eighteen months in Ravensbru¨ck concentration camp. Could these two events have been connected? His anonymous correspondent offered a tantalising set of clues that seemed to implicate Churchill and British Intelligence in the catastrophe.

Drawing on a deep knowledge of France and original research in British and French archives, War in the Shadows exposes the ruthless double-dealing of the Allied intelligence services and the Gestapo through one of the darkest periods of the Second World War. It is a story worthy of Le Carré, but with this difference – it is not fiction.
