“On Tuesday, fans get first crack at a DVD and Blu-ray set containing all three seasons of Sherlock, with outtakes, interviews, new commentaries and even collectible resin mini-busts, depicting the show’s two leading men.

Once fans devour this material, they’ll discover Sherlock’s last season gave more information than ever about the mysterious detective’s history — details Cumberbatch recites in our interview with the rapid-fire cadence from one of Sherlock’s famous speeches filled with deductions.

“You find out about Sherlock’s background,” the actor says. “You find out that he comes from a truly stable home. It was a gesture in the first episode, but you see that in practice in the third. You see that, as a boy he was deeply insecure — it begins as a taunt [from his older brother, Mycroft] … and that comes back to haunt him and he feels like a child. He’s reduced to feeling like a child.” ”
