"Talking of sudden disappearances the one you mention of Hannah in that Leavenworth case of ours, is not the only remarkable one which has come under my direct notice. Indeed, I know of another that in some respects, at least, surpasses that in points of interest, and if you will promise not to inquire into the real names of the parties concerned, as the affair is a secret, I will relate you my experience regarding it."

Anna Green was an early 20th century novelist. She was one of the first authors to write detective stories in America. Her stories are known for their well thought out plots and their legal accuracy. Although Green wrote in a genre previously dominated by men she did n think much of feminists and opposed women's suffrage. Her second novel A Strange Disappearance was published in 1880.
