Hercule Poirot and the Greenshore Folly

Sinopse

An urgent telephone call summons Poirot to Devonshire on what Miss Lemon declares is a "wild goose chase". The caller is the eccentric detective novelist, Mrs Ariadne Oliver, and the reason for her alarm seems based solely on woman's intuition. Is the fictional murder scenario she has been asked to devise a cover-up for something more sinister? And what is the significance of the Greenshore Folly, an architectural embarrassment in the sweeping grounds of the otherwise impressive Greenshore House?
