Detectives Lennie Briscoe and Ed Green investigate the shooting of a well-known writer of mystery novels, P.K. Todd. She is wounded and her business manager is killed. From the outset, Todd insists that she was the target, and the police initially focus on any fans who may have written to her. They soon learn that a woman, Carolyn Tyler, who identified herself as an FBI agent had been at Todd's hotel looking for her the night she was shot. The police immediately suspect that Tyler's husband Dean, also an FBI agent, was having an affair with the writer, but Dean Tyler vehemently denies an affair. DAs McCoy and Carmichael realize that they might been wrong about who was involved in the affair and the motive for the murder. They begin to suspect that it was Caroline Tyler who had the affair with P.K. Todd. Dean Tyler is charged with murder. His defense will claim Dean suffered from "psychosexual panic" resulting from his wife's having a lesbian affair.
