The first in a new cozy mystery series by Elizabeth Penney investigates a suspicious murder in a haunted British castle-turned-bed and breakfast.

Herbalist Nora Asquith is delighted to welcome Ravensea Castle's first guests to the picturesque village of Monkwell, Yorkshire. After a thousand years of ownership, her family has decided to convert the castle into a bed and breakfast. But when Hilda Dibble, a self-appointed local luminary, is found dead in the knot garden the next morning, Nora's business is not only at risk—she's a prime suspect.

Hilda had opposed the hotel plan every step of the way, and although she didn't succeed in stopping the venture, her disagreements with Nora seem to only further her motive. One of Ravensea's guests happens to be Detective Inspector Finlay Cole, who is new to the area and now finds himself with a murder case in his lap.

Nora and her actress sister Tamsyn decide to investigate for themselves. They look into the entangled dealings of their newly arrived guests, while also getting hints from Sir Percival, one of the castle ghosts. As they learn, Sir Percival's tragic death centuries ago sheds light on present-day crimes. Surely they can get to the bottom of this mystery while keeping their new business afloat . . .
