The Slasher by Ovid Demaris (Gold Medal #910 1959)
A homosexual, Christian hating psychopath kills, and continues to kill as a team of detectives hunt him down before he continues. Gritty, graphic, and suprisingly edgey, this quick read lets you inside the head of the intelligent, slippery serial murderer. Difficult to catch, the hardened, toothless antagonist escapes justice numerous times, and terrorizes them all the while. That is, until he meets his demise at the gunpoint of his pursuers.
Cheap thrills and loathesome depravity abound in The Slasher
