THE GRIPPING SUNDAY TIMES BESTSELLER

'A vastly entertaining tale, bursting with astonishing stories and extraordinary characters ... A fascinating read' Sunday Telegraph

'Brilliant ... An amazing story, one I hadn't heard too much about' Dan Snow

IT IS THE DEPTHS OF THE SECOND WORLD WAR.

The Germans like to boast that there is 'no escape' from the infamous fortress that is Colditz.

The elite British officers imprisoned there are determined to prove the Nazis wrong and get back into the war.

As the war heats up and the stakes are raised, the Gestapo plant a double-agent inside the prison in a bid to uncover the secrets of the British prisoners. Captain Julius Green of the Army Dental Corps and Sergeant John 'Busty' Brown must risk their lives in a bid to save the lives of hundreds of Allied servicemen and protect the secrets of MI9.

Drawn from unseen records, The Traitor of Colditz brings to light an extraordinary, never-before-told story from the Second World War, an epic tale of how MI9 took on the Nazis and exposed the traitors in their midst.

"'A brilliant book about Walter Purdy, one of the worst Nazi sympathisers who passed on information about British escape plans, including in Colditz Castle ... Us Brits don't like talking about traitors during the Second World War so Purdy doesn't fit the narrative. Purdy is an uncomfortable reality'" - Dan Snow's History Hit podcast
