A Game of Birds and Wolves takes us from the sweltering fug of a U-boat as the German aces coordinate their wolfpack, to the tense atmosphere of the operation room as the British team plot battles at sea on the map. The story of Operation Raspberry and its unsung heroines has never been told before. Investigative journalist Simon Parkin brings these hidden figures into the light and shows the ingenuity, perseverance and love needed to defeat the Nazis in this gripping tale of war at sea.
