Midnight Slasher - Deadly Obsessions, #1

Butch was a cold-blooded killer but he was also the victim of circumstance. He was raised by an evil, religious fanatic grandmother and an abusive, alcoholic father. When he was still a young man, he ended up in a foster home with a perverted foster father. It wasn't until he escaped to join the military that he learned how to get his revenge by using a large Bowie knife he had inherited from his father.
He enjoyed killing so much that he became a hired assasain but his favorite pastime was raping and killing shapely blonde women. When he was hired to kill a blonde female he had no idea it was just the tip of an iceberg.
