In the clip—released on the heels of an official image from the BBC—we get a glimpse into Sherlock and Watson’s lives in a scene that’s very familiar from the original Sir Arthur Conan Doyle books. After returning from investigating a crime, the two are welcomed home by their landlady Mrs. Hudson back at 221B Baker Street for some relaxation (and possibly more research).
The dialogue might be a tad more polite to match the times, but otherwise, nothing has changed. Sherlock is still curt, Watson is still overshadowed and wants to be taken seriously—he even grew a mustache to stand out!—and Mrs. Hudson still hates his writing.
Sounds about right.
Correction: In an earlier version of this article, we misidentified Mrs. Hudson, Holmes and Watson’s landlady.
