The murder of a pregnant girl leads Stone and Keller to arrogant radio host Terry Vine, who has a large female fanbase. The dead girl claimed to be pregnant with Vine's baby, giving him a motive for murder, and after her blackmailing roommate also turns up dead, Keller is convinced Vine is the killer.

Stone is assigned to partner on a cat burglary case with an inspector he has become romantically involved with and even proposed to. But when a woman is apparently murdered by the burglar, Stone's relationship with his new partner is strained as he believes the burglar is the killer, and she does not believe the murder fits the burglar's pattern.
