Angels of Darkness: a drama in three acts

This manuscript play was written around the same time as the Sherlock Holmes story A Study in Scarlet. There are some similarities in the plots of both stories, and many points of concordance in the names of the dramatis personae. Angels of Darkness even features a romantically-inclined medical man named John Watson, but is notably lacking a Holmes character.
