There are Protectors among us.

For as long as there have been human settlements, a chosen few cats have worked behind the scenes, always in the shadows, protecting humans and enabling us to prosper.

A Protector looks like any other cat. They are neither expressive nor reticent, and many are considered beloved house pets by humans. These humans are unaware of the cat's dual role, and Protectors work to keep it that way.

Belle, a newly minted Protector, is right in the mess when death has come to her town, Torrington, Connecticut, in the form of a serial killer. Along with her best friend Giblet, Belle has turned to a legendary detective to help solve this case, but is he even up for the challenge? From the slums of London to New York and Torrington, CT, will the Protector be able to stop this evil before another victim is claimed?
