Meet NICK SAX - a corrupt, intoxicated ex-cop turned hit-man, adrift in a stinking twilight world of casual murder, soulless sex, eczema and betrayal. With a hit gone wrong, a bullet in his side, the cops and the mob on his tail, and a monstrous child killer in a Santa suit on the loose, Nick and his world will be changed forever this Christmas. By a tiny blue horse called Happy... Collects HAPPY! 1-4.
