And yet appearances can be more than deceiving in the world of blackmail and extortion. The shocking gangland-style murder of known blackmailer Sy Kramer begs the question: which of Kramer's marks had given him his very last payoff? A politician's beautiful wife with a deadly secret? An overly interested ex-con? A wealthy soft-drinks executive? Or the mystery person who had fattened Kramer's wallet by the thousands? The detectives of the 87th Precinct must break the chain that links the dead man's associates and single out a killer -- before someone else cashes it in.
