Doctor Who Advent Calendar Twenty-Three

With now only two days until Christmas arrives, the BBC today opened door number twenty-three on their online Doctor Who Advent calendar, available exclusively on the official Doctor Who website. Inside today's door is the second part of a brand new Doctor Who story which saw it's first part released last week, entitled The Doctor on My Shoulder. Part one of the story, written by Daniel Roth, can be read inside the seventeenth door on the online Doctor Who Advent calendar by clicking here, whereas part two can be read inside the twenty-third door by clicking here. Tomorrow, the twenty-fourth of December, is Christmas Eve, meaning that door number twenty-four on the Advent calendar will be opened, and details regarding that will be posted here shortly after the new door is made openable.
