1st ed., 1989. Xvi + 423 pp., photo-plates + maps & tables. D.j., 24 x 16cm. FINE. Intelligence developed the way it did partly because of the kind of war World War I became. This book examines the emerging character of Intelligence and of the human problems entailed. It discusses the early opportunities with wireless, the development of codes and ciphers, and deals particularly with the remarkable men involved in this vital work. The story of Secret Service, special operations, spy rings, and the men behind all of these, is given serious study. The author’s findings have uncovered much new information about the First World War and in his view, work undertaken by British Military Intelligence shortened World War I by at least a year.
