American medieval history professor Dotsy Lamb and her best friend, Lettie Osgood, are working an archaeological dig in the Scottish Highlands on the grounds of Dunlaggan Castle when murder strikes. The victim is genial, well-liked graduate student Froggy Quale, the on-site pollen and spore expert. His roommate, the dig's media man, is the prime suspect, but Dotsy, quite fond of both boys, is convinced otherwise.
When the head of the dig, Dr. John Sinclair, dies of unnatural causes soon thereafter, Dotsy shovels a little deeper, suspecting there are some buried secrets in a dark family history. Closing in on a clever and desperate killer, Dotsy makes a stunning connection to poisoned mushrooms, ghostly noises echoing through the halls, and the discovery of a centuries-old gold coin that could rewrite the history of the 11th century.
