I saw a video today linking to this (frankly, kind of ridiculous) article that was published in March of 1941 by someone who argued (possibly in a tongue-in-cheek way, I suspect) that Dr. Watson had to have been a woman and Sherlock Holmes' wife. As I read this, I honestly wasn't sure if it was good enough to share, but I read the whole thing just because I wanted to see what this person would pull out next, so here it is. This entry only has the  first couple of pages, and then to read the rest you have to click on "Entire Issue" at the top of the page to go to the table of contents and select the article that includes the page of the continuation. 

I find the discussion of the dialogue between the characters as being similar to those between a husband and wife a little reminiscent of some fans' (conspiracy) theories, often quite a stretch, that I sometimes read back in the day. I don't think it's meant to be taken too seriously, or at least that's not how I'm taking it, but it is fun to think of how the two characters could have been like a married couple, if perhaps simply to show how close and familiar they came to each other, and the ways in which their differences in personality collide.
