Caitlyn is settling into life as a novice witch in an English village chocolate shop - although she's finding the hardest magic to master is making caramel sauce without burning it! When two men are murdered, and a mythical black hound is seen haunting the countryside, the village gossips are sure dark witchcraft is to blame. Caitlyn decides to do a little magical sleuthing of her own. Luckily, she has her very own shape-shifter to help her (even if he does come in the shape of a toothless old vampire) not to mention her naughty kitten Nibs, and her sassy American cousin!

But her investigation soon leads to unexpected revelations about the mysterious runestone necklace she wore as a baby. Can Caitlyn find the killer and unlock the secrets of her past? And will she ever convince the dashing Lord James Fitzroy to accept who she really is?
