Windsor Horne Lockwood III - or Win, as his few friends call him - doesn't know how his suitcase and his family's stolen painting ended up with a dead man. But his interest is piqued, especially when the FBI tells him that the man who kidnapped his cousin was also behind an act of domestic terrorism - and that the conspirators may still be at large. The two cases have baffled the FBI for decades, but Win has three things the FBI doesn't: a personal connection to the case; an ungodly fortune; and his own unique brand of justice.
