Christie's most successful and popular books hold a pattern. Her writing subtely encourages you to suspect everyone except the real murderer, who you ignore. Even when you know the rules of her writing and the tricks she plays, she is so brilliant as to still deceive you. Appointment With Death fits that pattern, and as such is a very pleasing read for fans of classic Agatha Christie. There are a limited number of suspects in an isolated area, and details of times and locations are added to muddy the waters. However, there in the middle of the situation is Poirot, quietly confident. As usual, if you have a mind like Poirot's and are really paying attention, you can work it out. For us mere mortals, there is always the answer at the end of the book, and very satisfying it is too.
