The story of how the O.S.S. grew, the sort of operatives and methods it employed, the schemes and techniques of financing its activities, and the things it was able to accomplish for the war effort still makes exciting reading, even this many years after the W.W. II. Alcorn served with the organization from its earliest days, yet his overall picture is one of uncommon harmony for such a complex effort. The emphasis is on people rather than techniques: he has a real grasp of how to project human-interest material. The thrills, chills, and tears are well balanced, and the effect is exhilarating.
