In addition to the novel length stories and one play, Hercule Poirot appeared in more than 50 short stories published starting in 1923 in "The Sketch," a British illustrated weekly journal that ran between February 1, 1893 and June 17, 1959. "The Sketch" published 23 stories published in 1923. These early stories represent almost half of all the Poirot short stories written by Agatha Christie over the 50 plus years of the detective literary life. Later these stories were published in book form as part of the collections "Poirot's Early Cases" and "Poirot Investigates," sometimes with a different title. After an extensive illustrated introduction to Poirot and to the stories, this eBook presents in their chronological order of magazine publication, with the original magazine title and publication details.
