A comparison of this collection of 50 of the greatest detective stories with the anthology edited by Dorothy Sayers shows this to be a distinctly less scholarly and more popular collection. There are about 20 repeats on authors, but only two on actual stories. The Sayers' collection includes the supernatural; the whole of literary output has been tapped; this is mainly contemporary- only about eight authors are not still writing today. There's a fairly wide range of types, but virtually all classify as straight detective-mystery stories, not horror stories or stories of the supernatural. The division is not by type of story, but by great men detectives, great women detectives, etc. Short stories all, with each introduced by a brief paragraph, personality note, indicating when the particular detective in question appeared on the scene. Poe, Doyle, Agatha Christie, Dorothy Sayers, Dashiell Hammett, Mary Roberts Rinehart, Marjorie Allingham, and so on down the roster of familiar names.
