At the beginning of the novel, Satterthwaite and Poirot are both attending a dinner party hosted by the stage actor Sir Charles Cartwright at his home in Cornwall. When one of the other guests, the Reverend Babbington, suddenly drops dead after taking a sip of his cocktail, several people suspect murder – yet there are no traces of poison in his glass. Soon afterwards, another death occurs under similar circumstances at a party attended by many of the same guests, but this time the victim is confirmed to have died from nicotine poisoning. Are the two deaths connected and if so, did the same person carry out both murders?
