We have seen three fabulous episodes of this short burst of Doctor Who already, and we're moving on to the fourth and penultimate one. This time, it looks like the Doctor is heading back to modern day Earth to team up with the Ponds on their turf to solve an intriguing mystery. The official blurb: "The Doctor and the Ponds puzzle over an unlikely invasion of Earth, as millions of sinister black cubes arrive overnight..." What could it all be? And will, as Lukeh so diligently spotted, there be a mention of Christmas?
