Today, for our eighteenth festive gift, we bring you the third and final instalment of our exclusive Christmas tale, The Doctor Calls.

It’s time for the Doctor to bid farewell to Edward and the children for another year, and you can find out just how it ends by clicking here to be taken to our Advent Calendar index, then clicking the box for Day 18! Enjoy!

Don’t forget that you can still vote for your favourite Tenth Doctor moment here, and the results will be revealed on New Year’s Day, the day on which his final ever episode, part two of The End of Time, will be broadcast.
