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. Haynes devised complex plots in her works and combined the style of nineteenth century sensation novels with Golden Age detective fiction. In her work, the emotions of female protagonists and themes of scandal, secrets and romance often took precedence over the detective plot line. Her novels are lauded for their quick-pace action and sustaining aura of suspense till the end.
