Thanks for that.
Sherlock Holmes being another interest of mine, I welcome his introduction to the Forums here.
According to the excellent Red Flame site, other Sherlock Holmes stories involving Aleister Crowley include:The Case of the Philosopher's Ring
by Dr John H Watson, unearthed by Randall Collins (NY: Crown Publishers 1978) Hardback. - "It is the summer before the outbreak of World War I. Holmes, at his Baker Street flat, receives a telegram from the brilliant young philosopher, Bertrand Russell, begging him to come to Cambridge to investigate the theft of a uniquely precious treasure - the mind of Ludwig Wittgenstein. ... Holmes and Watson set out to investigate some of the West's greatest minds. But the trail plunges suddenly out of the abstract and into the blood and guts of occult murder, when Aleister Crowley, the high priest of post-Edwardian mysticism, enters the picture." This one often appears on eBay for auction. Doctor Watson and The Invisible Man
by Noel Downing (England: Ian Henry Publications 1991) Hardback. - "In 1897 H.G.Wells told the story of Griffin, the man who became invisible and then could not return to normal. When he died he left his notes at the public house that later bore his name. Then years later the journalist, Langdale Pike, calls at the Invisible Man, negotiates to buy the notebooks and goes to London to get the cash from his newspaper; before he can return to Sussex the landlord of the pub is murdered and the books stolen. Pike turns to his friend Doctor John Watson for help and, in the absence of Sherlock Holmes abroad, Watson applies Holmes' methods in tracking down a killer. The trail leads to a self styled magician, Aleister Crowley, and from him to another literary figure, Arthur Machen. Watson and Pike are involved in a number of incidents leading to the Imperial German Embassy and so to a house in Half Moon Street, where strange discoveries are made. Aided by Mycroft Holmes, Crowley and Scotland Yard, Watson can report success to Sherlock Holmes when the consulting detective return from the continent."Sherlock Holmes Reader, The Loch Ness Horror
written by Martin Powell, illustrations by Seppo Makinen (England: Tome Press 1998) Comic Books.The Case of the Scarlet Woman, Sherlock Holmes and the occult
by Watkin Jones (London: Greenwich Exchange 1999) Paperback. - "A haunted house, a mysterious kidnapping and a poet's demonic visions are just the beginnings of three connected cases that lead Sherlock Holmes into confrontation with the infamous black magician Aleister Crowley and, more sinisterly, his scorned Scarlet Woman."
