MURDER BEING ONCE DONE
From the Inspector Wexford series, volume 7
by Ruth Rendell
Wexford, a Surrey policeman (you'll like him), chooses to take a holiday in London following a thrombosis where he gets well quickly submerging himself in the murder of a girl called Loveday Morgan, found in a cemetery vault. No one really knows who she war or what happened to the child she had apparently had and Miss Rendell, an expert in deadending garden paths, will lead you up and down by the nose. In a pleasant, literate fashion.
