Barrat and Kerit, the assassins from Alter Egos, have a new client. Her husband was killed by a serial killer assassin named Diamond Jin. At first the only clues they have is his choice of weapon and method: He stabs his victims with a steak knife in the heart, making the scene look like a random mugging when it is anything that simple.
Can the duo track down Diamond Jin's base and his ledger of employers before many more victims die, and what will Jin do to the beautiful model that he's using to validate one of his cover identities if she discovers his secret?
