Following the German occupation of Holland, the Special Operations Executive parachuted in over fifty secret agents. Most were captured and executed. Eleven of the RAF planes that brought them were shot down. Using recently released documents from the National Archives, this book tells the story of three remarkable women, Antonia Hamilton, Trix Terwindt and Jos Gemmeke who, despite these setbacks, volunteered to be flown out of RAF Tempsford, 'Churchill's Most Secret Airfield', and parachuted back to play vital roles on top secret missions prior to liberation.
