The Complete Cabalistic Cases of Semi Dual, the Occult Detector, Volume 1: 1912

One of Pulpdom’s earliest occult detectives returns! Running for over twenty years in the pages of The Cavalier, All-Story Weekly, The People’s Magazine, Top Notch, and Argosy, among others, these tales have never been reprinted until now.
Volume 1 contains the first three tales of Prince Abdul Omar AKA Semi Dual, all from 1912: “The Occult Detector,” “The Significance of the High ‘D’,” and “The Wistaria Scarf.”
This premiere collection includes an all-new introduction by Garyn Roberts, Ph.D.
