DS Mark 'Heck' Heckenburg is used to bloodbaths. But nothing can prepare him for this. Two years ago, he put the ringleader of The Nice Guys Club - a vicious rape and murder gang with countless victims- behind bars. But Heck knows that this depraved organisation stretches far beyond UK shores. When brutal murders start happening across the country, it's clear that the Nice Guys are at work again. In cold blood, broad daylight and by any means necessary, the Nice Guys have no boundaries. And Heck knows it won't be long before they come for him.
