[Fic, Sherlock] Tumblr Fic: In which John was in Middle Earth at the Time

Title: In Which John was in Middle Earth at the Time
Series: Sherlock
Characters: Sherlock, John
Rating: G
Type: Gen, drabble
Warnings: None
Notes: The title explains it all? Also, I blame the Sherlock Facebook page, which has become a repository for Sherlock memes posted Internet-ages ago on Tumblr. I couldn't help myself.

( Mobiles don't function in Middle Earth! )
