Synopsis: Professor Moriarty, upset he didn’t get to fill Pulaski with crumpets, commandeers the ship.
Memory Alpha Summary: A little device sitting on someone’s table.
Review: Now this is everything Elementary, My Dear Data was not. There is a tension throughout as we try to navigate all the twists and turns. Moriarty is once again brilliantly played by Daniels Davis, and Barclay is a perfect fit. The ending is cunning and sweet. A near perfect episode.
