I just finished reading No Police Like Holmes, about a mystery at a Sherlock Holmes colloquium. Publication date: 2011. 

Many characters are dedicated Sherlockians, as in, members of BSI or scion societies.

At one point, the characters are discussing actors who have played Holmes, and these include Basil Rathbone, Arthur Wontner, Jeremy Brett, Robert Downey Jr., "and somebody named Cumberbatch."

It's kind of wild to realize that the BBC series and the Guy Ritchie movies have been around long enough that other books have been published referring to them. 

But here's what really funny. Correct me if I'm wrong, but I think 2011 is earlier than BBC-Reichenbach?

Well, as you may know, one of the "creeds" of Sherlock Holmes societies is that Holmes was a histroical figure, not a fictional character. Exhibit A:

So, some of the characters who are members of those kinds of societies wear buttons that say....


Sherlock Holmes Lives!
