Uncut Terror (Executioner)

Diamonds Aren't Forever 

A legendary Kremlin assassin slaughters an American defector before he can be repatriated. Not about to let the murder go unpunished, Mack Bolan sets out to even the score. 

His first target is a Russian businessman with ties to organized crime, a man who was unexpectedly released from a Siberian prison. Bolan tracks him to the World Diamond Council meeting in New York City, where the Russians reveal their deadly endgame. Only one man can stop their scheme to crash the Western economy and kill hundreds of innocent people—the Executioner.
