Who got killed in Grover Park?

It's just another ordinary day at work for aging 87th Precinct detective Steve Carella and his partner Artie Brown. They're out on the streets, investigating a particularly heinous—and unusual—homicide. A young woman's body has been found in Grover Park; she's been strangled to death. If this isn't bad enough, the autopsy reveals that the murder victim is a nun. Matters get even more complicated when it turns out that this sister of mercy had breast implants. It seems that Sister Mary Vincent—for it is she—had quite a few personal and financial problems in her life.
This complex, disturbing case will require Carella to use all his powers of deduction and draw upon his vast experience as a detective to get to the truth of the matter. That he's able to this while dealing with a serial burglar who leaves behind cookies for his victims, makes us admire Carella all the more.
