The Ingenious Mr Pyke
Inventor, Fugitive, Spy
Geoffrey Pyke first came to prominence when he escaped from a German prison camp in 1915. His ingenuity and energy subsequently produced experiments in various fields from stock-market speculation to educational theory and, during the Second World War, both Churchill and Mountbatten championed his extraordinary military inventions. Drawing on recently declassified files, this biography analyses his gift for innovation and considers whether he may have been spying for the Russians, as the files suggest. Slightly off-mint.
