It is autumn in Castle Knoll and Annie Adams is busy settling into her new home. She doesn’t find Gravesdown Hall particularly cosy, especially since she found two dead bodies there over the summer. What’s more, ever since she arrived in the village, Annie has had the creeping sense she’s being watched.

Lonely, and desperate for some company, Annie starts talking to a stranger she meets in the grounds of the estate. The striking old woman introduces herself as Peony Lane, the fortune-teller who predicted Great Aunt Frances’ murder all those years ago. And now she has a fortune to tell Annie.

Desperate not to fall into the same trap as Frances, Annie flees Peony Lane, refusing to hear any of her grim predictions. But she can’t outrun Peony for long, as hours later she finds her, dead on the floor of Gravesdown Hall, a ruby-hilted dagger plunged into her back.

But who killed the mysterious fortune teller and why? And can Frances’ library of evidence help Annie solve the case?
