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.

From the Foreword. In 1949, while I was visiting Ezra Pound who was a political prisoner at St. Elizabeth's Hospital, Washington, D.C. (a Federal institution for the insane), Dr. Pound asked me if I had ever heard of the Federal Reserve System. I replied that I had not, as of the age of 25. He then showed me a ten dollar bill marked ""Federal Reserve Note"" and asked me if I would do some research at the Library of Congress on the Federal Reserve System which had issued this bill. Pound was unable to go to the Library himself, as he was being held without trial as a political prisoner by the United States government. After he was denied broadcasting time in the U.S., Dr. Pound broadcast from Italy in an effort to persuade people of the United States not to enter World War II. Franklin D. Roosevelt had personally ordered Pound's indictment, spurred by the demands of his three personal assistants, Harry Dexter White, Lauchlin Currie, and Alger Hiss, all connected with Communist espionage.

The untold story of the three intelligent and glamorous young women who accompanied their famous fathers to the Yalta Conference in February 1945, and of the conference's fateful reverberations in the waning days of World War II.
