Grayson: "You've been stewing in honey too long. How could you know that?"Watson retains the job of the opening narration, though now in a metallic voice.Lestrade drives Holmes and robo!Watson to the Reichenbach Falls to see the place where Holmes buried Professor Moriarty in 1891. Holmes makes a quip at Lestrade's driving and catches sight of a large pine tree which, in a flashback, saved his life two centuries ago. Remember, the opening of the previous episode showed Moriarty and Holmes going over the edge. Holmes somehow managed to grab hold of a sapling (which somehow managed to hold two tall men's weight). Holmes was holding Moriarty's hand, but they could not keep their grip on each other, and Moriarty fell.Back in the 22nd century, Lestrade lands at an ice cave near the Falls. Inside the cave, the trio meets the spectacle of Professor Moriarty's corpse, perfectly preserved in ice. Lestrade is aghast. If that's Moriarty, then who is the man running around New London with his face? Holmes even says that the man had no descendants.A cave-in promptly occurs, sending our heroes back outside. (It's the first and unfortunately not the last time that Holmes will make some cry of alarm that does not at all sync with the action.) Professor Moriarty is now buried forever.They return to New London to find that the crime wave mentioned in the previous episode is getting way out of hand. Worse still, people who previously had no criminal records are suddenly committing robberies. New London-wide. Holmes sets off to investigate, and Chief Inspector Grayson reluctantly allows Lestrade to join him. Holmes offhandedly remarks that the robot tag along. This casual attitude (displayed throughout the episode and heightened to annoyance) will come back to bite him later.
Holmes: "Careful observation and perceptive thought: eyes and brains."
