Twenty years of man-hunting, by a G-man, reveals the training from raw operator to expert bloodhound. This is the personal story of getting the fugitives back into jail, sending the wrong guys up, learning the rackets inside the pen, learning and knowing the signs, indications, tell-tale give-always of the smarter than the law boys. It's the stuff behind the headlines, the long, hard way of the Department of Justice and its F.B.I. members, the always fascinating ways of outside the law big and small guns, the even more interesting methods of approach, attack and apprehension by the lawmen. There are names and cases -- Lindbergh, Poletti, Patton, Mike Jordan, Central Registry of War Criminals and Security Suspects, organized prostitution, extortion, -- almost the whole criminal book, if not quite the whole world on assignments, civilian and war -- for a personal recountal which includes the author's search for his dead son, of the 8th Air Force, missing over Italy. Good first person account for criminology as well as detective minded readers.
