Captain England

In the short story The Under Dog, Captain England is a guest at the Golf Hotel at Abbots Cross, near Mon Repos, the residence of the Astwell family. Poirot enquired into the movements of the hotel guests in the course of his investigation into the death of Sir Reuben Astwell. According to Miss Langdon, the hotel manageress, Captain England and his wife had gone out for dinner on the night of Sir Reuben's death but this was not of concern to Poirot. He was looking for someone who might have gone for a walk after dinner in the direction of Mon Repos.

Captain England is not featured in the film adaptation of the story in Series 5 of ITV's Agatha Christie's Poirot.
