On a lovely moonlit night, while carrying a gift of mice to a litter of kittens, Joe Grey stumbles upon a murder scene. Behind an empty house, in an empty swimming pool, there’s blood, the smell of human death, and drag marks. But there’s no victim - and it’s hard to prove a crime without a corpse.

With the help of local ferals, Joe, Kit, and Dulcie must now thwart a killer using the most unorthodox means at their disposal: a criminal’s unnatural yet powerful fear of cats.
