Doctor Who Advent Calendar Day Seventeen

With now only eighth days until Christmas, the BBC's official website for Doctor Who was today updated with the seventeenth door on their Advent calendar. Inside today's door is the first part of a Doctor Who story, written exclusively for the official Doctor Who website by Daniel Roth, entitled The Doctor on My Shoulder. The first part of the story can be read by clicking here inside the seventeenth door on the official Doctor Who website's Advent calendar, and the second part will be available to read inside one of the doors which will be made openable in a few days time. The eighteenth door on the calendar will be openable at some point tomorrow, and some details regarding its content will be posted here, on The Gallifrey Vortex, when it is active. What do you think of today's Advent surprise?
