In 1954, Agatha Christie wrote this novella with the intention of donating the proceeds to a fund set up to buy stained glass windows for her local church at Churston Ferrers, and she filled the story with references to local places, including her own home of Greenway. But having completed it, she decided instead to expand the story into a full-length novel, Dead Man's Folly, which was published two years later, and donated a Miss Marple story, "Greenshaw's Folly", to the church fund instead. This book features Hercule Poirot.
