Jack Sinclair is no different from any other fifty something, widowed insurance salesman. Except that for a sideline, he kills people . . . for money. When a publicity driven attorney begins a crusade to free the self-confessed killer of Jack's wife, Jack takes it upon himself to make things right by killing the attorney. He gets away with it, or so he thinks, until a self-styled vengeance broker named Eddie blackmails Jack into doing more killing to keep his secret. After several years of doing Eddie's bidding, Jack agrees to do one last job, but winds up falling in love with the intended victim. When Jack makes the decision to protect Allison Wesson, instead of killing her, he becomes a target of hired assassins. The story has several plot twists, and Eddie, the vigilante, becomes an ingratiating character as he aides Jack in his efforts to save Allison's life.
