The Colleagues of Professor Van Helsing
An Anthology of early and seminal occult detectives from the middle to late 1800s. The sub-genre that gave birth to such modern series as the X-files. From Ghost maestro J. Sheridan Lefanu through popular mystery writers such as Algernon Blackwood, L.T. Meade and Robert Eustace, through occult wroters like Dion Fortune and Aleister Crowley to the master of horror writing Arthur Machen.
