After learning that she comes from a family of witches - and adopting a familiar named Alistair - artist Anabelle Britton has made beautiful Portsmouth, New Hampshire her home. Togther with her coven, this good witch is trying to put a stop to magic and murder most foul. When Anna takes Alistair to see local veterinarian Ramona Forsythe, they meet the most famous cat in town: Ruby the Attitude Cat, spokes-feline for a pet food brand. But then Ramona turns up dead and Ruby goes missing. It seems like the murderer used magical means, so it's up to Anna and Alistair to catch the killer and cat-napper as only a canny cat can.
