Cop Hater
Evan Hunter
 The city has surrendered to a heat wave in July 1956. When detective Mike Reardon is on the way to work on the nightshift, he is shot to death from behind with a .45 caliber handgun. As Steve Carella and his colleagues from the 87th Precinct are looking for their friend's killer, they have no idea that this is just the beginning of a series of police murders. David Foster is the next victim, at the entrance of his apartment, where the killer has left behind a footprint at the crime scene. Steve Carella and Hank Bush question the family and wives of the deceased, as well as some suspects, but to no avail. A few nights later the unknown killer ambushes and murders Det. Hank Bush. Bush fought back however and shot and wounded the murderer. Steve Carella fears he will be the next target if he fails to stop him. When Carella is leaving the precinct, he finds a reporter, Savage, waiting for him. He asks Carella his thoughts on who the killer might be, stating that everything is off the record. Carella reveals that - due to the evidence collected from Bush's murder - the police now knows certain attributes of the killer, i.e. weight, profession, and build. Carella leaves telling Savage that he is going on a date with his girlfriend, Teddy. The next day we find out that Savage has published the conversation between him and Carella, including Teddy's name and address. When Carella finds this out he rushes to Teddy's apartment, hoping the killer is not already there. When Carella arrives at Teddy's apartment he hears shouting and cursing coming from inside. With his .38 in hand, Carella enters Teddy's room and is immediately faced with a man aiming a .45 right at him. Carella drops to the floor the instant he enters the room and shoots the man holding the .45 twice in the thigh. After making sure Teddy is okay, Carella interrogates the man, finding out that his name is Paul Mercer and that he was the murderer of all three cops. After further interrogation it is discovered that Alice Bush was behind the whole plot; she had convinced a previously unknown man named Paul Mercer to commit the murders. Apparently she had promised him her affections once he had killed off her husband. In the end, both are sentenced to death for their crimes and Det. Carella marries his girlfriend, Teddy Franklin.
