A cold, brutal killer is stalking the streets of the quiet residential suburbs, committing the most shocking and audacious crimes imaginable. His victims are blonde, single middle-aged women living alone. His method of killing is simple but effective: he smashes their head in until they're dead. No one sees his come or go. He leaves no clues that are of any use. And the local women are living on their nerves. Carrie McElhenry would seem to be the ideal victim. She's a blonde, single professional woman living on her own in the quiet suburbs. The thing is, she's the ambitious detective inspector assigned as senior investigating officer to the case, and she's determined to catch the Spinster Killer come what may. It's the case of a lifetime, and she'll follow every lead to bring the ruthless monster to justice. The only trouble is, there's no evidence to go on. Every clue leads nowhere, each lead comes to a dead end. There are no witnesses, no motives, no suspects. There's no sign of a struggle at any of the crime scenes, just a single dead woman. It's almost as if the killer is a phantom on a mission ... Meanwhile, the deaths are coming in thick and fast, and the bodies are starting to pile up at the morgue, each one distinguishable by a ruined skull and a pulped face. But there's also another feature of the so-called "spinster killings" - each of the victims has been sexually violated by a household object and posed post mortem. The killer's confidence is growing. He wants to make a statement and he's starting to taunt the investigators. He's starting to enjoy himself! DI McElhenry thinks she's the woman to catch the killer, but her superiors are starting to have doubts. She's beginning to feel the pressure, because if she doesn't start getting results soon ... well, she could very easily be replaced. But there's also the most important motive of all ... DL McElhenry does not fancy being added to the list of the Spinster Killer's victims.
