Earlier this week, the official synopsis for the 2012 Doctor Who Christmas Special was released by the BBC:

Christmas Eve 1892 and the falling snow is the stuff of fairy-tales. When the fairy-tale becomes a nightmare and a chilling menace threatens Earth, an unorthodox young governess, Clara, calls on the Doctor for help. But the Doctor is in mourning, reclusive and determined not to engage in the problems of the universe. As old friends return, will the Doctor really abandon humankind or will he fight to save the world – and Christmas – from the icy clutches of this mysterious menace.

What we know:

• Jenny, Madam Vastra the Silurian and Strax the Sontaran (all last seen in 2011's 'A Good Man Goes To War') will return

• The villain, Doctor Simeon, is played by Richard E Grant

• Evil, sentient snowmen are the monsters

• Jenna-Louise Coleman will return, playing a character called Clara. Is she the same person as Oswin Oswald, whom we saw in 'Asylum of the Daleks'?
  

With only 26 days to go until The Snowmen appears on our screens, now's the time for the speculation to start. What do you think will happen in the episode? Will we find out about the relationship between Clara and Oswin (if one exists)? Comment below to share your thoughts!
