DS Mark 'Heck' Heckenburg is used to bloodbaths. Two years ago, he put the ringleader of The Nice Guys Club - a vicious rape and murder gang - 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. And Heck knows it won't be long before they come for him.
