3.14 The Female Of The Species Take this week’s reappearance of Gina Gershon’s mob boss. Elana Marsh was last seen thirteen episodes ago being put away by Watson in the season three opener. Elementary hadn’t forgotten about her in the meantime, it was simply waiting to harvest the seed planted all those months ago. It was a structurally neat return for Gershon’s character, who bracketed Watson’s experiment in flying solo as a PI. Marsh was there for the beginning of Watson’s enterprise, and her death coincided with its conclusion. Andrew’s misadventure with the poisoned latte has convinced Watson that a normal life was beyond her reach, and to work like Sherlock she must live like Sherlock. It’s goodbye swish apartment and hello early morning wake-up calls at the Brownstone for Joan. One thing the show’s creators do have judging by this week’s episode, is a mothballed evil genius – or deus ex Moriarty if you like – one who can henceforth be called upon to clear up messes off-camera from the comfort of her jail cell, wherever it is she’s being held (King’s Landing, last time I checked). Natalie Dormer’s voice made a welcome return at the end of The Female Of The Species, fixing Watson’s assassin problem and promising that the game wasn’t over yet. Are we going to see more of Moriarty in season three? Cross your fingers, toes, and eyelids for the possibility. When he wasn’t adorably delivering groceries and making lasagne for his pal, Sherlock was involved this week in a yelpingly fun case the likes of which you just don’t see on other detective shows. I’m pretty sure that The Adventure Of The Two Stolen Pregnant Zebras isn’t strictly canon, but it nevertheless has my vote for pure bonkers fun. The Quagga plot wasn’t just inventive and entertaining, it also incorporated several facets of the classic detective mystery. We had a locked room mystery, secret tunnels, a ‘the killer is in this very room’ moment – in short, a tonne of great stuff. Read Frances’ review of the previous episode, Hemlock, here.
