Master of the Moor — Ruth Rendell

Stephen Whalby loves to walk the moor. He considers it his, although he and his young wife Lyn are merely tenants in a flat nearby. But the senseless and frightening murder of a young woman invades Stephen's sense of privacy and pollutes his beloved moor with suspicion and dread. And then a second murder captures his imagination in an unpredictable and fascinating way . . .
