One day, author John Green finds Benedict Cumberbatch hiding in his office. Many of us would be happy with that. But what do you do when Benedict is convinced he is Sherlock, and that the television show Sherlock is a ruse set up by Moriarty and must be shut down?

But the path back to the set of Sherlock is not an easy one, or a fully clothed one, or one that can happen on dry land. Benedict doesn't seem to know that there is more than one John in the world, and he believes all of the fanfic he has ever read. Also, Doritos.
