Peril At End House (1932) by Agatha Christie
Pbk, Harper Collins, 222 p.
When I was much younger I was a huge fan of the classic British mystery authors, Ngaio Marsh, H.R.F. Keating, and Agatha Christie. I've tended to keep away from the older police procedural mainly because of repetition that tends to pop up over and over. I do like to pick up the odd Hercule Poirot mystery because you can never go too wrong with the eccentric detective book.
In Peril At End House, Poirot is on vacation at the Cornish resort of St. Loos when he meets a beautiful young woman at the hotel. She tells him of three recent "accidents" that she had escaped possible death from. When she returns home her hat is left behind and Poirot discovers a bullet hole in it leading him to believe that her life truly is in danger. A very pleasant mystery follows with a good cast of characters and even a real murder in the midst of it all.
