I couldn't leave out Agatha Christie!!
Synopsis from amazon.co.uk: It is Christmas Eve. The Lee family reunion is shattered by a deafening crash of furniture, followed by a high-pitched wailing scream. Upstairs, the tyrannical Simeon Lee lies dead in a pool of blood, his throat slashed. But when Hercule Poirot, who is staying in the village with a friend for Christmas, offers to assist, he finds an atmosphere not of mourning but of mutual suspicion. It seems everyone had their own reason to hate the old man! To mark the 80th anniversary of Hercule Poirot's first appearance, and to celebrate his renewed fortunes as a primetime television star, this title in a collection of facsimile first editions is the perfect way to experience Agatha Christie. Reproducing the original typesetting and format of the first edition from the Christie family's own archive, this book sports the original cover which has been painstakingly restored to its original glory.
