With rain crashing down on her Range Rover, as it climbs up a steep embankment on the Northumberland moors, Lori Shepherd is beginning to doubt the wisdom of her decision to evaluate a rare book collection at Wyrdhurst Hall.

The grim, neo-gothic hall that greets her upon arrival is full of surprises-including a charming, secretive stranger, and a cache of World War I letters that tell a tale of doomed love and hint at a hidden treasure. It will take all of Dimity's supernatural skills to help Lori solve the puzzle and restore peace to a family haunted by its tragic past.
