For starters, there are two unpublished Hercule Poirot stories in this wonderful book. When Agatha Christie died in 1976, Christie’s daughter, Roslind, found 73 handwritten notebooks full of lists, notes, and outlines of Christie’s novels, plays, and stories. John Curran deciphered Christie’s handwriting and organized the mountain of material into a useful volume for a Christie fan. I learned something new about Christie’s work on every page. If you’re a fan of Agatha Christie, this is a must-buy. If you’re a casual Christie reader, you’ll find plenty of interesting material here to make your reading experience deeper and more enjoyable.
