This is complicated; we’ve tried to simplify it here. For example, Hercule Poirot’s Christmas was actually released in December, 1938 but its copyright date is 1939. We listed it under the copyright date. More detailed information about the publication dates, etc. can be found in Agatha Christie reference works such as Agatha Christie: A reader’s Companion by Vanessa Wagstaff and Stephen Poole. Sometimes there was a difference in the UK and US publication date, and some works had different titles for the U.S. edition. Though we’re in the U.S., ours are the British editions, so we are going by those publication dates titles. If applicable, we’ll list the U.S. title in parenthesis. Novels 1920.

Short Stories Many of the short stories, having appeared in a magazine or newspaper, would later be published as a collection, although in some instances with different titles than those used in the periodical version, and the plots may have been altered and/or expanded. So, the stories within a collection would typically have been written earlier than the publication date of the book. Some stories were not collected until decades after they were written (we sorted those out and will note them separately below). Some of the collections were not released in the UK, and vice versa – we’ve noted those too. 1924. Poirot Investigates (Poirot) All of these stories had first appeared in a UK magazine in 1923. The US edition of Poirot Investigates, published in 1925, also included "The Chocolate Box," "The Veiled Lady," and "The Lost Mine." These stories had appeared in the US in a magazine between 1923 and 1925. 1929. Partners in Crime (Tommy & Tuppence) The stories had appeared in UK magazines between 1923 and 1928.
1930. The Mysterious Mr. Quin For the most part, these stories had been published in UK magazines between 1923 and 1929, and in US magazines between 1925 and 1929.
Is That All There Is? No! We created the list above for those who might wish to create an authentic 1920s/1930s library. But Christie wrote many other short stories during that time that contemporary readers would have had access to in magazines and newspaper supplements and/or mystery anthologies. Some of these Art Deco era stories were collected into books in later decades, as follows: 1947.
