I did a lot of research for my Displaced Detective Series, and I'm very proud of the accuracy I achieved in depicting Sherlock Holmes and his world. As many Sherlockians and Holmesians know, however, at least early in thestories, Holmes was a drug addict. His preferred drug seemed to be intravenous cocaine, although he was also known to use morphine in the same way.In investigating this drug use, I came upon some possible "ulterior motives" for Holmes' usage of cocaine in particular. When I was invited to present a scholarly paper (of sorts; Holmesians have a great sense of humor and have alot of fun) at the 8th annual Gathering of Southern Sherlockians, I decided to put together what I had learned about cocaine use in the Victorian era, and what effects it had. It was very well received at the Gathering, and a writer friend suggested I offer it as an e-publication; hence the resulting production. It makes for interesting reading, and in my opinion, explains many of the great detective's idiosyncracies muchbetter than the usual suggestions of Asperger's, ADD/ADHD, bipolar disorder, and the like. It certainly gives one pause for thought, and addsa new dimension to Holmes.
