Killshot

Ironworker Wayne Colson and his spirited wife Carmen are witnesses to a shakedown scam—witnesses who must be eliminated. Enter Armand Degas (aka Blackbird), the brains of the operation, and his partner Richie Nix, an ex-con whose highest goal is to rob a bank in every state. After the Colsons enter the Federal Witness Security Program, a lively chase ensues—with two bumbling but determined killers on Wayne and Carmen's trail.
With its dead-on dialogue, memorable characters, and absolute authenticity, Killshot is one of Elmore Leonard's all-time great novels.
