This monograph by a professional thief—with the aid of Edwin H. Sutherland's expert comments and analyses—is a revealing sociological document that goes far to explain the genesis, development, and patterns of criminal behavior. "Chic Conwell," as the author was known in the underworld, gives a candid and forthright account of the highly organized society in which the professional thief lives. He tells how he learned to steal, survive, succeed, and ultimately to pay his debt to society and prepare himself for full and useful citizenship. The Professional Thief presents in amazing detail the hard, cold facts about the private lives and professional habits of pickpockets, shoplifters, and conmen, and brings into focus the essential psychological and sociological situations that beget and support professional crime.
