Left: Leo Marks (24 September 1920 to 15 January 2001) the head of SOE’s codes and cyphers based at Michael House Baker Street, London. Right: his adversary in the Netherlands Abwehr (German Military Intelligence) Lieutenant Colonel Herman Giskes who was responsible for the wireless deception resulting in many SOE agents from the Dutch Section and members of the resistance being captured and executed. People who knew Marks said his brain was wired differently and could workout complex problems and it was Marks who discovered the Abwehr wireless deception alternatively called the ‘wireless game’ and ‘Englandspiel’ (England Game).
