Plot Summary:Driving down a country lane at night, Joyce believes she has hit somebody but there is no evidence to support this. However, unpopular village librarian Gerald Ebbs is found murdered in a nearby graveyard, of which he was voluntary caretaker. Most of the graves are for T.B. patients from an adjacent but long disused sanatorium. Assistant librarian Sarah Sharp benefits from the death of Gerald, who was frequently at odds with ghost walks organizer Jeff Bowmaker. Bowmaker runs tours through the graveyard and is having affairs with two married women, landlady Alice Carver and historian Faith Kent. When Joyce joins a ghost walk which explores the sanatorium a second victim is claimed, enabling Barnaby to discover how his wife believed she had disturbed the silent land.
