As a break from the boring chronology posts, here's another bit from my DIM novel. Recall that there's a love triangle going on between Holmes, Watson, and Helen Stoner in the 1880s, during their bachelor days. However, Holmes has rejected Helen Stoner since Chapter 21, when he visited her in New York and briefly met Irene Adler in 1884.
Since 1886, Watson has become friends with a fellow doctor, who is also an author. In fact Conan Doyle helped write the Mormon part of A Study in Scarlet, and got the novel sold to a publisher, though they lost the copyright in the deal. The publisher is holding the novel for a year due to the glut of "cheap fiction", and will publish it in December 1887. Meanwhile, the two writers correspond and discuss which other case they should make into a novel next, because then they can keep the royalties and maybe make money. So Watson has written up "sample stories" of some cases such as the Copper Beeches to show to Doyle. As they discuss Holmes in their letters, Doyle asks a question about Holmes's drug use, and this is Watson's response. Notice that he carefully lies and suppresses the full truth about his "strange brief affair" with Holmes in 1887.
