Lady Anne is herself at the receiving end of a puzzling murder mystery when the killer strikes her for hiring a private detective. Would Inspector Furnival be able to solve the mystery of the double murders and find the criminal before it's too late? Annie Haynes (1865-1929) was a renowned golden age mystery writer and a contemporary of Agatha Christie, another famous crime writer, which often led to her comparison with the latter, and unfavourably so. Haynes's fictions are now lauded for their quick-pace action and sustaining aura of suspense till the end.
