Dead Man's Folly - Agatha Christie 1956 - Published for The Crime Club, London - First Edition An exquisitely bound first edition in which Ariadne Oliver, the famous crime writer who bears a passing resemblance to Christie, sets up a murder mystery event at a local fete, and invites her old friend Hercule Poirot to the West Country.

Unsurprisingly, the party provokes a real murder. A salutary lesson in Sod's law: if you intend to host a murder mystery party, do not invite real detectives.

According to Cooper and Pike’s
Detective Fiction, the grounds and boat house of the author’s home, Greenway House, in Devon, were used as some of the novel’s locations.
  Dame Agatha Christie, Lady Mallowan, DBE (1890-1976) - the first of the really distinguished women writers in the field of detective fiction.
