In The Holodeck

[elementaire]

This holodeck, as they called it, was really quite extraordinary. It wasn't Sherlock's first time in it, of course, but it was his longest uninterrupted time in it. He was currently standing on a street in no city he could identify; probably not one from his world, either in the planetary or dimensional sense of the word (or both), for all that the people looked human. He had been making notes in his communicator, and now he felt ready to move on to another décor.

"Computer," he requested of the AI apparently running the virtual reality chamber. "Random simulation, if you please."

As the world shifted around him, a rectangle marked the opening of the door, and Sherlock frowned sadly. It could only have lasted so long.
