Yes, this is an official BBC-sanctioned manga of A Study in Pink.
The manga is a fun way to get your Sherlock fix during the hiatus and brush up on your detective vocabulary in Japanese, but the real reason I want to recommend this is how the artist captured Benedict-Cumberbatch-as-Sherlock’s hilarious facial expressions. Oh, it’s Christmas, readers.
SHERLOCK ピンク色の研究. Manga by Jay. Screenplay by Steven Moffat and Mark Gatiss.
Meretricious and a happy new year!
