In July 1933, the gangster known as George "Machine Gun" Kelly staged the kidnapping-for-ransom of an Oklahoma oilman. He would live to regret it. Kelly was never the sharpest knife in the drawer, and what started clean soon became messy, as two of his partners cut themselves into the action; a determined former Texas Ranger makes tracking Kelly his mission; and Kelly's wife, ever alert to her own self-interest, starts playing both ends against the middle. The result is a mesmerizing tale set in the first days of the modern FBI, featuring one of the best femmes fatales in history-the Lady Macbeth of Depression-era crime-a great unexpected hero, and some of the most colurful supporting characters in recent crime fiction.
