In addition to receiving the Iron Cross from the Germans for her wartime contribution as a nurse, Marthe Mckenna (née Cnockaert, codename ‘Laura’) was later mentioned by Douglas Haig in British Despatches and was awarded the French and Belgian Orders of the Legion of Honour for her espionage work. I Was A Spy! was first published in 1932 with an extended Foreword by Winston Churchill and was made into a film in 1933 directed by Victor Saville and starring Madeleine Carroll. The success of the book encouraged Marthe to write further memoirs of her wartime exploits, and those of her small band of fellow spies, and also led to a series of espionage novels written in collaboration with her British husband John “Jock” McKenna.
