Miss Clegg

In the short story The Market Basing Mystery, Miss Clegg was housekeeper of Walter Protheroe who was found dead under puzzling circumstances in a locked room in his house. Miss Clegg had come with Protheroe when he had bought "Leigh House" in Market Basing some eight years earlier. She later told Poirot that she had known him for far longer, having been nursemaid to him as a boy.
