Incubus by Ray Russell. paperback edition. ISBN: 9780722175606.

HELL INCARNATE... Tim tried to get her to move. He kept talking to her. "Come on, weve got to get you out of here. Whats wrong?" He touched her. Melanies face split in two as her mouth stretched wide in a scream that never stopped... Galen is an ordinary, peaceful small town - until horrendous terror strikes... and strikes again and again, each time claiming a female victim in a manner too hideous to imagine. Julian Trask, student of the occult, is used to thinking the unthinkable. As he works toward the solution of the soul-searing mystery, Galen trembles in mortal dread. For no woman is safe from the lethal lust of THE INCUBUS.
