A quiet market town with no military presence was chosen as the secret communications centre for Britain as the country prepared for war with Germany in 1937. When hostilities began, ' Q Central' attracted a dozen other clandestine operations set up to defend the country or designed to confuse and undermine enemy morale. The headquarters of radar, RAF Group 60, also came to Leighton Buzzard to be hidden from German attack and to be close to the telephone and radio communications needed to run its vast chain of radar stations. These directed the defending fighters that saved the country in the Battle of Britain and then took the bombing war to Germany. Close by, for the same reasons of secrecy and safety, were the satellite stations of Bletchley Park, the now famous code-breaking centre; the Met Office at Dunstable, which gave the all clear for the D-Day landings; Black Ops units that set up false radio stations and wrote propaganda to confuse the enemy; and airfields used for dropping agents behind enemy lines. At Q Central itself was the largest telephone exchange in the world, with more than 1,000 teleprinters communicating with all the armed services in every theatre of war and directing the operations of the secret services. Now the restrictions of the Official Secrets Act have been lifted, enabling eight members of the Leighton Buzzard and District Archaeology and History Society to piece together this compelling story for the first time.

Dickie Metcalfe was not your typical secret agent, but he was larger than life in more ways than one. Unlike many other agents who were part of the Double Cross System during the Second World War, he did not defect; nor was he blackmailed into becoming a spy. Instead, using his father’s connection with Sir Vernon Kell, the first Director of MI5, Metcalfe volunteered his services. Recently cashiered from his infantry regiment, he had an ulterior motive – by supplying MI5 with tidbits of information about weapons and arms deals in his newfound profession as an arms dealer, he hoped they would be able to help him get his commission reinstated. Metcalfe became BALLOON, a sub-agent of double agent TRICYCLE’s Yugoslav spy ring. Concurrent with his spying activities, he collaborated with the co-inventor of the Bren gun to develop a new submachine gun for British forces. After the war, he was also a celebrated motor racing driver and continued to compete until shortly before his death. His success as a double-cross agent in the eyes of both his masters – British and German – is examined in this book, using official documents as a primary source.
