Hercule Poirot receives a telegram from baronet Gervase Cheveny-Gore asking for help in a delicate matter. Poirot arrives before dinner, for which quite a few guests have already gathered. And then a gong sounds, and after some time a shot. It's time for Poirot to get down to business again. The story is a slightly expanded version of the story "The Second Strike of the Gong", first published in July 1932 in issue 499 of the Strand Magazine.
