The Tragedy of the Silver Moon by Arthur Gask

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.

The Professor was a man of varied attainments, and in his time had been a chemist's errand boy, an employee in the Zoological Gardens, a kennelman to a veterinary surgeon, a conjurer, and a chauffeur and handyman to an East End practitioner of medicine. From the experiences gained in these occupations he now carried on a very successful practice as a quack doctor, styling himself "Professor" to avoid trouble with the police.
