Since Sherlock's (Benedict Cumberbatch, The Fifth Estate, Star Trek: Into Darkness) return, it seems that no one great criminal has stepped up to challenge him. But His Last Vow reveals an evil mastermind at work deep beneath the surface. Charles Augustus Magnusson (Lars Mikkelsen, The Killing) is just a businessman, a newspaper owner, but somehow he owns the most powerful people in the western world. Now Sherlock and John Watson (Martin Freeman, The Hobbit, The Office UK) find themselves facing off with this slippery, loathsome man-and with one of his victims.
