The Dutch resistance movement during the Nazi occupation was bedevilled by treachery, betrayal and poor organisation and support from London. Despite these serious problems, the brave men and women of the Dutch resistance who refused to accept domination by their brutal oppressors, made a significant contribution to the war effort albeit at a terrible cost. Their contribution which included escape routes for Allied aircrew and acts of sabotage has been largely overlooked. While the author focuses on the activity and fate of her husband’s father, Henry Scharrer, her superbly researched book ranges far wider. As well as introducing a large cast of resistance workers, double agents and Nazis, she describes many of the operations, successful and disastrous, and analyses the results. Too often, as in Henry Scharrer’s case, the outcome was tragic. This gripping true account of extraordinary heroism and betrayal demonstrates both the best and worst of human conduct in extreme conditions.
