All of which makes the line in the Special about that country squire so interesting. My mind first connected that line with the Holmes Srs, or perhaps Sherrinford/the other one, but there are other country squires in the canon.
The weird thing is that I don't actually like "Dancing Men." At all - it just bores me as a story, and Elsie Cubitt is sickeningly innocent in it for my tastes, the story lacks all mystery or even anything besides what strikes my modern sensibilities as a thoroughly avoidable tragedy, and it's just not a very compelling story to me. (A modernized look at what a spouse with a dark past actually owes her life-partner in terms of expectations, and what she can reasonably keep to herself could be quite interesting, if it critiqued Elsie's secrecy in a nuanced way, but as the story stands...) Why should I want Mary as Elsie when I could have, say, Mary as Bob Carruthers?
Still, the thrill of the chase, the blood pounding through one's veins. I love that the idea feels new, and that it feels like mine, and if the special isn't some weird combination of "Dancer" and "Bicyclist" I think I will be very disappointed.
