(set in 1899, written in 1927, published in 1928)
“Shut up, you fool! Do you suppose your grotesque nonsense has any weight with me? Words and formulae – words and formulae – what do they all mean to one who has the substance behind them? We’re in a material sphere now, and subject to material laws. You have your fever; I have my revolver. You’ll get no specimens, and I’ll get no fever so long as I have you in front of me with this gun between!”
Written by Adolphe de Castro and H.P. Lovecraft, the Bad Guy in this Gaslight story is clinic-man Surama, a man of dubious extraction and allegiance.
Surama used a revolver of unspecified make and model. We can assume that he acquired it in America rather than brought it from North Africa. A suitable choice would be a Colt New Army & Navy revolver in .38 Long Colt (9×26mmR) or a S&W Safety Hammerless revolver (Investigator Weapons 1: The 1920s and 1930s, p. 57) in .32 S&W (7.9×15mmR) or .38 S&W (9×20mmR).
