It's about pirates. Kind of.
It's about a pirate known as Black Peter who left a book that showed where treasure and/or a wreck was, I think? I dunno for sure because I lost interest pretty quickly. Anyway, it was clear the minute the murderer appeared on screen that he was the one, so I mostly waited for them to come around to the same conclusion.
I guess what happened was, a guy found the Black Peter book and tried to find someone to go with him to the wreckage and salvage the treasure, but then someone else killed the guy because he wanted the treasure to not be there because there was some investment scheme. Wait . . . Then why not just let the guy with the book go get the treasure anyway? Oh, wait, because there was a thing about a professor who wanted all that stuff to go to a museum . . . I dunno. It wasn't all that interesting.
Oh, but then the Shinwell stuff. Groan. Holmes confronts him about having murdered his friend/fellow gang member, and of course Watson is all of two minds about the whole thing, and then the episode ends with Shinwell attacking and threatening Holmes, telling him not to get in his way while he takes the gang down.
Okay. There is a kernel of something good in here that has been wildly mis-sown. The idea of Holmes training someone only to have them flip and become evil? That's fantastic. Love that. But Shinwell is not a compelling character, not as a good guy and not any more so as a bad one. What a missed opportunity.
Six more episodes, I believe? Elementary was not on CBS' early list of renewals, though it has not been officially cancelled either. It, along with a handful of others, hangs in the balance.
