Sherlock has inspired countless copycats, fan videos and parodies, but none of them drop the 221-Beat like this incredible musical version from YouTube channel The Hillywood Show.
Vlogging comedy duo Hilly & Hannah Hindi have reimagined Sherlock Holmes and John Watson as a crime-fighting, rap-spitting double act – the Game really is on.
And, if you watch all the way to the end, you will spot a special guest appearance from Sherlock co-creator Steven Moffat and his son Louis.
It’s not just musically pitch perfect: the pair travelled to London to film in actual Sherlock locations from episodes including A Study in Pink, The Great Game, A Scandal in Belgravia and The Sign of Three.
Producer Sue Vertue took to Twitter to congratulate them.
