The third episode of Series 2, The Reichenbach Fall airs at 9pm on Sunday 15th January on BBC One and sees Sherlock and John lock horns with their old enemy in one final problem that tests loyalty and courage to their very limits.

Speaking to CultBox in the edit suite in Cardiff last year, Haynes revealed that the episode is “a heist film really” and “the tone is action-adventure”.

He added that Moriarty’s plan is “less of a game and more of a trap” and is “all about reputation and trying to destroy [Sherlock]”.
