Dreaming in Digital

I was in a foreign country with Cookie and Sherlock from Elementary. We were solving a mystery of some kind, but I'm not sure what it was. I was left to stay in the hotel room with tiled, creme floors and white walls, and beds with fluffy, white comforters, while the two went out in different directions to search for clues. It was raining outside and we were in an old, city built with red and brown bricks.
