Today is the twenty third of December and there are now only two days to go until Christmas day and the premiere of The Next Doctor. Door number twenty three on the BBC's official Doctor Who advent calendar is now available to open and behind it is a jigsaw puzzle for The Next Doctor. Once the jigsaw has been completed, a clip from this year's Doctor Who Christmas special will become available. This particular clip isn’t new and a longer version of it can be found here in a previous post. You can access the jigsaw maker here. What do you think of today's advent calendar treat?
