A con man always has a bag of tricks, ready to fool the unsuspecting, and almost everyone is unsuspecting until they get taken. When that happens, they turn to Carpenter and Quincannon, Professional Detective Services, to recover their money and what's left of their dignity, and perhaps even to save their lives. When one such case leaves Sabina Carpenter the only witness to a murder, the family of the culprit vows to stop at nothing to keep her silent. The threat leaves John Quincannon deeply concerned for Sabina's safety, but there's no rest for the wicked and so the crime-solving duo must split up to tackle two separate con games, run by two villains with deadly bags of tricks at hand. And when Sabina's life is put in danger, John must rush to save her while grappling with the terrifying realization of exactly how much she means to him.
