Cleaner / Paul Cleave.

Novel.

"Meet Joe. He's a nice guy out to catch a copycat killer. The one copying himself. Joe is in control of everything in his simple life, including both his day job at the police department and his 'night work'. He remembers to feed his fish twice a day and visit his mother at least once a week, although he occasionally peppers her coffee with rat poison. He is not bothered by the reports of The Christchurch Carver, who - they say - murdered seven women. Joe knows the carver has killed only six. He knows that for a fact. And Joe is going to find that copycat killer, punish him for the one murder and then frame him for the rest. It's a perfect plan because he already knows he can outwit the police. All he has to do now is take care of all the women who keep getting in his way..."--Publisher information.
