Book excerpt: This is the first volume of Nigel West's acclaimed presentation of these fascinating diaries from the heart of Britain's Second World War intelligence operations. 'No intelligence buff can be without this volume and anyone interested in British twentieth century history needs it too.' M.R.D. Foot, The Spectator 'Regarded by historians as the most important military intelligence documents from the whole of the Second World War.' Irish Independent '[A] unique insight into the espionage secrets of the Second World War. Its historical importance is enhanced by the editing of Nigel West who, apart from decoding several obscure references to the secret war, persuaded the Security Service to break their rule of maintaining an agent's anonymity.' BBC History Magazine WALLFLOWERS is the codename given to one of the Security Service's most treasured possessions, the daily journal dictated from August 1939 to June 1945 by MI5's Director of Counter Espionage, Guy Liddell, to his secretary, Margo Huggins. The document was considered so highly classified that it was retained in the safe of successive Directors General, and special permission was required to read it. No other member of the Security Service is known to have maintained a diary and the twelve volumes of this journal represent a unique record of the events and personalities of the period, a veritable tour d'horizon of the entire subject. As Director, B Division, Liddell supervised all the major pre-war and wartime espionage investigations, maintained a watch on suspected pro-Nazis and laid the foundations of the famous 'double cross system' of enemy double agents. He was unquestionably one of the most reclusive and remarkable men of his generation, and a legend within his own organization.
