This is a story about cats. Who have a murderer among them. Told from the perspective of a cat. You may want to stop here. This may not be the book for you. This is a mystery seen through the eyes of out hero Francis. Francis is new to the neighborhood and is shocked to learn that many of his feline "family" are being murdered.

In attempting to solve the crimes, Francis is thrown into a world he didn't know existed. He learns of a bizarre cult where the local cats worship a long-dead cat named Claudandus. He finds out about a lab in the neighborhood where the humans performed heinous experiments on cats. He even comes across a new breed of cats.
