Author's Summary: John and Sherlock stumble across a strange blue box in Trafalgar Square. And that's the least weird thing to happen that day.
Characters/Pairings: Ninth Doctor, Rose Tyler, Jack Harkness, Sherlock Holmes, Dr. John Watson
This is a crossover that just had to happen, because the Doctor and Sherlock have so much in common. Dealing with arrogant geniuses provides a number of parallels between John Watson, Jack and Rose too. The story manages to blend the two universes together in a way that honors both, and stays true to the characters. I don’t want to spoil anything, so I’ll just say that there are fun twists and turns throughout, and an absolutely delightful ending.
