The House in Charlton Crescent by Annie Haynes is about the widow Lady Anne Daventry who tries to get detective Bruce Cardyn to find out who is trying to murder her. Excerpt: "Lady Anne Daventry was not a pleasant old lady. Her nearest and dearest found her difficult to get on with, her servants called her "cantankerous," and her contemporaries—those who remembered her in her far-off beautiful youth—said she had a good heart."
