An after exams stroll through Cambridge to visit my friend at one of the colleges (which will not be named for privacy reasons) yielded this:
Moriarty is real!
Most colleges have a habit of painting the names of the occupants in every room of a staircase/building on the wall by the entrance and above their doors if there is space. The person who lives next door to Prof. Moriarty's office is none other than J. Watson! All we really need is an S. Holmes! I would upload the photo but it has so many names on that it would impossible not to identify the place.
