Sherlock fans, how well do you remember the super sleuth’s deductions?

It already feels like an eternity ago when the Sherlock series 3 finale, “His Last Vow,” hit our screens, revealing that James Moriarty (Andrew Scott) had somehow survived the events of “The Reichenbach Fall.” Since then, fans of the super sleuth have been left without much information on the show’s future.

In fact, all we really know for sure is that Sherlock will be back, not just for series 4, but for a Christmas special prior to that.

Next year, Benedict Cumberbatch, Martin Freeman, Amanda Abbington and Mark Gatiss will reunite to start filming what Steven Moffat calls “the very last thing you’d expect.” BBC One also promised “the most shocking and surprising” series yet. After the events of “The Reichenbach Fall” and “His Last Vow,” the writers will have to have something mightily impressive up their sleeves to top their past efforts. Either way, we’re still at least a year away from our latest dose of the 221B boys, so there’s plenty of time to kill.

And what better way to waste the wait away than testing yourself on the show’s past episodes?

Sherlock‘s iconic deductions were one of the main draws when the series first started, with the witty observations and unique visual style captivating viewers. But they’ve also been useful clues. Super sleuth fans were able to work out that Mary had a secret when Sherlock deduced she was a “liar” in “The Empty Hearse.” But how many of the deductions can you remember?

For each of the following ten questions, you’ll be provided with a phrase from one of the great detective’s deductions, and you’ll have to identify the character who was being observed.

Can you match Sherlock’s intellect? Elementary, my dear reader…
