Agatha Christie Wiki

Poirot and the Regatta Mystery is a 1936 short story written by Agatha Christie which was first published in Canada in Star Weekly, 2 May 1936, in the USA in The Chicago Tribune, 3 May 1936, and in the U,K. in The Strand Magazine in June of the same year. Thereafter, Christie rewrote the story to feature Parker Pyne instead of Poirot and called the new story The Regatta Mystery. The original Poirot version was not published again until 2008 when it was included in the omnibus volume "Hercule Poirot: The Complete Short Stories".


A diamond merchant and his party step off their yacht to enjoy the festivities at shore. But when the youngest member of the party, Eve Leathern, decides to play a trick with a £30,000 diamond named “the Morning Star”, the fun suddenly escalates into a dramatic jewel theft. The most suspected member of the party begs Hercule Poirot to solve the disappearance of the valuable gem, pleading that he is not the thief. But if he isn’t, who is?

Film, TV, or theatrical versions[]

Largely forgotten and now usually known as a Parker Pyne story, the original Poirot version was not adapted in the ITV series Agatha Christie's Poirot although the stated intention was to dramatize every story.

Publication history[]

The story was later rewritten by Christie to change the detective from Hercule Poirot to Parker Pyne before its first book publication in the US in The Regatta Mystery and Other Stories in 1939.
