Lars Mikkelsen—the brother of Hannibal's Mads Mikkelsen, who's also known for playing mayoral candidate Troels Hartmann in the original Danish version of The Killing—will have a bit of an argy-bargy with velocipede-riding toff Benedict Cumberbatch on the upcoming third season of Sherlock.

Mikkelsen will play Charles Augustus Magnussen, who as far as we know is a powerful mutant who can control metal using only his mind. An alternate theory is that Magnussen is a reworking of the title character from Arthur Conan Doyle's original Holmes story "The Adventure of Charles Augustus Milverton," a blackmailer who targets the nobility.

No premiere date has been set yet for Sherlock's third season, on either side of the pond.
