The Tragedy of the Silver Moon [EPUB ebook] 

PROFESSOR PARIS STARBANK, for so he called himself, had a long string of letters after his name, but they did not indicate diplomas which had been granted to him by any recognised university or college and were quite worthless as far as his ability in any walk of life was concerned. Their meaning was of course, unintelligible to most people, but they meant that he belonged to the Society of Natural Healers, was a member of the Dietetic Brotherhood, and had joined the Union of Universal Therapeutists.
