Beware of the cat striking back. On a lovely moonlit night, Joe Grey is minding his own business, carrying a gift of mice to a litter of kittens, when he stumbles upon a murder scene. Behind an empty house lies a swimming pool, its bottom covered with mud. There is also blood, the smell of human death, and drag marks. But there is no victim. Without a body, it's a crime that will be hard to prove. With stubborn feline curiosity, Joe Grey sets out to investigate. As he, Dulcie, and Kit follow the killer's trail among four houses whose owners are on vacation, they discover that more murder has been planned for the small, close-knit neighborhood. They uncover evidence of conflict among the residents and multiple signs of breaking-and-entering, although nothing valuable seems to be missing. With the help of two local ferals, the cats find the victim's hidden grave and learn of the violence that is yet to come. As they set out to alert the law, they discover the perfect way to thwart the killer.
