The Exham-on-Sea's History Society's annual summer picnic comes to an abrupt end when human bones are discovered beside historic Cleeve Abbey. Even as the society organizes a ghost hunt, Libby Forest is more concerned about a culprit who is very much alive—and her doubts are justified when a friend is attacked. In this eighth outing (after Murde at the Gorge), Libby, her husband Max, and their two dogs set out to uncover the connection between the murder of a 16th century monk and present-day mischief in Somerset.
