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, knowing the signs, indications, tell-tale give-aways of the smarter-than-the-law boys. The stuff behind the head-lines, 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, methods of approach, attack and apprehension. Good first person account.
