Alfred Richmond

In the novel Hallowe'en Party, Alfred Richmond is the Chief Constable whose county includes Woodleigh Common. At the end of the story, Poirot brings the results of his investigation to him. There is little information given about which county Richmond is in charge of but Woodleigh Common is about forty miles from London. Ariadne Oliver also talks about going "down to" Woodleigh Common, suggesting that it is south of London.
