With one felon dead and another in jail, Mark Stone hunts for the last man behind his wife’s death

It was apparently a simple break-in gone wrong that left his wife dead, and Mark Stone consumed with guilt. He relentlessly tracks down the killers, uncovering a complex web of deceit. But one slips through his grasp.

Now, hungry for revenge, he picks up the trail. But the murderer has connections to professional criminals, and the hunter soon becomes the hunted. It will take all of Mark Stone’s ingenuity and brawn to evade their traps and turn the tables on them.

Can he take on evil men who’ve spent their lives on the wrong side of the law? Can he get justice for his wife? Can he find peace for himself?

A gripping, action-packed game of cat-and-mouse in which only one man will come out on top.
