In this first novel by Agatha Christie, published in 1920, she introduces the inimitable Poirot, who would go on to appear in 33 Christie novels and 54 short stories. The plot of The Mysterious Affair at Styles deals with a straightforward case of an old woman poisoned with strychnine for the obvious reason: her money. The way Christie handles a plot, however, nothing is ever straightforward. The story spirals round and round, leading the reader in one direction, then another, convincing the reader that first one character, then another is the guilty party. This edition contains illustrations from the original text.
