In 1954 Agatha Christie wrote a novella which was intended to raise money for her local church. Upon completion she was so taken with the story that she decided to develop it into a full novel, and submitted a different story to the fundraising effort. The work she had originally written was called Hercule Poirot and the Greenshore Folly, and this work was expanded and eventually published in 1956 as Dead Man’s Folly.
