A term we don't hear as frequently these days is "gypsy." Unless you're headed to see a Sondheim musical, which is about an entirely different Gypsy (and one with Sherlockian connections too).
Anyway, our focus here is on stories in which gypsies are mentioned (there are two; can you name them?) and a bit of historical context of gypsies in the Victorian era, including the documented experience of one exalted person. It's just a Trifle.
