Sherlock Is Bored (As Usual)

When Sherlock and John find a seemingly simple police box, Sherlock seems troubled. He deduces that it is not, after all, a real police box, but a fake. He then proceeds to go inside….and meets a very strange man. They soon are joined by three other mysterious strangers- 'hunters,' as they call themselves. (I don't own Sherlock or doctor who - duh. Johnlock, destiel and possibly sabriel.)
