Given his physical description (that every modern adaptation opts to ignore… wonder why…), the name similarity to English literature’s most famous European Jew, and the real life influence of Harry Houdini, I would really love an adaptation of Sherlock Holmes that embraced the idea the Holmes family are closet Jews.
The funny thing about Arthur Conan Doyle and him (famously) falling for that stuff with the two little girls and their obvious hoax cardboard cut-out fairies. Sherlock Holmes would have seen through that shit in a minute. Of course he would have.
When you write a fictional character that’s actually smarter than yourself.
