Well played, Elementary. Well played.
You kept me guessing until the very end. Elementary Season 4 Episode 7 started with a classic 'corpse in the woodchipper' scenario, followed by an impostor kidnapee, a flashbang, and the real kidnappee saved.
Fake Mina was brilliantly manipulative, to the point where Sherlock described her as one of the best liars he's ever met. And this from the guy who was in love with Moriarty!
