Watson didn't know what Holmes was working on, and honestly didn't want to know. He'd been fiddling with a miniature golden hourglass that he had acquired somewhere for the past couple of hours. Watson had put his briefly seeing two of Holmes in the room an hour ago down to an overactive imagination, he certainly didn't see one of the Holmeses put on his hat and inverness and race out the door.
"Hmmm, maybe it's the sand." Holmes muttered as he reached for a hammer which he promptly used in a rather crude attempt to disassemble the hourglass.
Suddenly there was a windstorm inside the room. Sand and various loose items blew about in a circle around Holmes and the unfortunate doctor. As suddenly as the windstorm began, it stopped. The room looked much the same except for the crowd of wide eyed people being ushered back by men in strange robes holding sticks.
Holmes had quickly moved towards the window. Frowning, he gestured for Watson to follow. Outside, the street had changed a great deal. In what seemed an instant, the buildings had been replaced with unfamiliar ones, the ubiquitous carriages had been replaced with strange wheeled devices painted in a wide variety of colors that moved along the oddly paved road without the assistance of any outside entity. The people who walked along the street wore all manner of strange, and in the case of the women, improper attire. The women were wearing trousers for heaven's sake!
"Watson, do you have any idea as to how to get us home?" Holmes asked.
Watson blinked, tore his eyes from the strange sight in front of him, turned to his friend and said "I'm a doctor, not a wizard."
