(set in 1889, written in 1893, revised in 1929, published in 1930)
Of course I had my revolver in my coat pocket, but any motion of mine to reach and draw it would be instantly obvious.
Written by Adolphe de Castro and completely revised by H.P. Lovecraft, this story is set in the Gaslight era, or more exactly in the Old West. That the unnamed investigator carried his revolver in a pocket does not necessarily indicate a small pocket revolver, as many people at the time carried even rather large weapons in pockets, although often fitted with short barrels. A Colt Single Action Army revolver in the so-called Sheriff’s configuration in .45 Long Colt (11.43×33mmR) (Investigator Weapons 1: The 1920s and 1930s, pp. 42-43) would be quite likely. A pocket weapon like the S&W Safety Hammerless revolver in .32 S&W (7.9×15mmR) or .38 S&W (9×20mmR) (Investigator Weapons 1, p. 57) would also be possible.
