Lara Pulver has dropped some hints on her role as Irene Adler in the second series of Sherlock.

Pulver will appear in the first episode of the new run entitled, A Scandal In Belgravia, written by Steven Moffat.

Pulver told Digital Spy: “Steven Moffat’s written an episode about Sherlock dealing with what love is, rather than Sherlock really knowing what being in love is. We’re both very much playing a mind game with each other. We’ve met our matches with each other.”

Asked about a possible romance between the pair, Pulver said: “It’s kind of deeper than romance. It’s kind of infatuation.”

Sherlock returns early 2012.
