Elementary - While You Were Sleeping

"You may not have noticed, detectives, but his man has been shot!"
(Featuring replacement second cop, Detective Bell (Jon Michael Hill.)

Elementary continues with a robbery/homicide which proves more complicated than at first appears. The robber turns out to have seen the murderer, and gives a spot on description... of a woman in a coma. As Holmes begins to discern a complex and cold-blooded plan, he must struggle with the skepticism of new police liaison Detective Bell and with Watson's attempts to fix him.

'While You Were Sleeping' combines a thoroughly modern mystery with plenty of proper Holmsian twists: The complex plotting over a relatively simple crime; the plausible-sounding but probably quite doubtful methodology of the killer (monkey glands, anyone;) a violin; and of course a chance for Holmes to expound his theory of finite brain capacity vis a vis his parentally-mandated AA meetings.

The episode also highlights one of the key differences between this Holmes and Doyle's original: Doyle's Holmes was blunt, but polished in his public manner; this one is a rampaging bull in an emotional china shop. I say this not as a complaint. Sherlock is similar, and I suspect for the similar reason that a modern Holmes does not have to negotiate as strenuously polite a society as Victorian England. This is Holmes with his few remaining social filters shut down by a world without formal courtesies.
