This collection includes the title story, in which the young American Sherlock Holmes teams up with the great occult detective, Sar Dubnotal, to defeat a monstrous creature from beyond, as well as a never before translated original Harry Dickson tale from 1935 which lifts the veil over one of the detective's earliest cases in post-War 1919 Germany. This volume also includes four more stories by G. L. Gick, two of which appear here for the first time, featuring such legendary pulp characters as Doctor Omega, Irma Vep of the Vampires, Tros of Samothrace and Madame Atomos.
