9/7/1976 Miss Marple's last case appears

September 7, 1976.  This day saw the American publication of Sleeping Murder, which Agatha Christie wrote during the second World War and tucked away to be a posthumous curtain call for herself and Jane Marple, the beloved spinster from St Mary Mead. 

A newlywed has an apparent deja-vu memory of a murder.  Is it ESP, or something more sinsiter.

Kirkus Review sasy "This is Miss Marple at her noticing, unobtrusive, kindly best--a perfect envoi."
