Flossie Carrington

In the short story The Plymouth Express, Flossie Carrington is the daughter of the extremely wealthy industrialist Ebenezer Halliday. She was found murdered, stabbed to death, on board the train from London to Plymouth. She had been travelling with her maid Jane Mason to a house-party at Avonmead Court, the Duchess of Swansea's place. Her case of jewels, worth some hundred thousand dollars was missing.

Poirot had met Flossie in Paris some years before the events in the story when her father had introduced her to him. At that time, she had developed a romantic interest in one Count Armand de la Rochefour. Her father considered him highly unsuitable and took her back to America. Some time later, she married Rupert Carrington, who, as it turned out, was no better. The marriage soon fell apart because of his gambling habit. At the time of the events in the story, Flossie and Rupert had been living apart for some years although she had frequently acceded to his demands for money in order to avoid a scandal. More recently, she had commenced divorce proceedings. At the time of her death she was also known to have rekindled an affair with Count de la Rochefour.
