The BBC has this afternoon offered us all a clue. At some point in the next few hours brand new Sherlock series three pictures will appear in a gallery on their site.
It could be anytime before 5pm, we understand. And that is all we know.
We're hoping for lots of new glossy photographs of Benedict Cumberbatch and Martin Freeman, and maybe some more clues about what's in the new series.
