The Sherlock Holmes society closest to where I live is called the "Stormy Petrels." I'm embarrassed to say I don't remember how that's a Sherlock Holmes reference.
The way I learned that the group existed was kind of funny: a theater in town shows classic movies every so often, and they were showing the Hound of the Baskervilles starring Basil Rathbone. On the way inside, I thought I was seeing people wearing deerstalkers and trenchcoats.
Then, before the film started, a theater employee made announcements and asked, "Do we have any Stormy Petrels here tonight?" And applause broke out, acknowledging that they were.
