This is Moffat at his best. A short, sweet story that manages to deliver a very human, emotional impact. I'm sure all of us on this forum are deep, devoted Doctor Who fans who have a connection to the show, books, audios, or whatever else that runs deeper than the average person and this story reminds me of why I love it and why the Doctor is a hero. At 19 pages and free to read, I think every fan should give it a read x
