What a coincidence! Sherlock is also retained by the police of New Scotland Yard as a consultant. Watson retracts his computer line back into his arm. Not at all, I thank you for your concern. He's very polite, even for a compu-droid.

Sherlock abandons his stop-and-look inspection of the floor in frustration. "Bah, there are only Moriarty's footprints here," he says, rising and going over to the curious black ring impressed on what's left of the back wall. He runs a finger through the corroded substance, rubbing it between his fingers. "Carbon scoring...curious."


It's then that his attention is caught by what Mr. Cranston is doing to the computer console. "Do be careful, I would hate to have Watson pull you out of there."
