Recently I listened to Hugh Fraser read the unabridged Peril at End House.  He is the actor who superbly portrayed Col. Hastings in the A&E Poirot series many years ago, and he is a wonderful voice actor.  After years of treating Christie's works as a buffet table to be ranged over as the mood or a theme struck me, I am reading them in chronological order, and here I was at Peril at End House (1932).
