Ghost Monster by Simon P. Clark
Pel Minton is opening graves in a cemetery for an archaeological dig, but this particular cemetery contains a disturbing portrait which is known by local children as 'The Ghost Monster.' For centuries this grim image has imprisoned the spirit of Justice Murrain and his vicious gang of misfits, but soon these sadists will enjoy the darkest of pleasures...A chef carves human flesh with a pizza cutter. A laughing thug films his own death-dive from a cliff. People binge on mayhem, fighting until streets run with blood. These are the Possessed. Death will not stop them...
