This story is part of a collection of stories commissioned to celebrate the 50th anniversary of the tv series. There is one new short story for each of the Doctors. I was excited that two of my favorite authors Eoin Colfer and Derek Landry contributed to the series and they did not disappoint. Eoin Colfer wrote an adventure for the first Doctor that of course captured the feel of the original show but also added several twists of his own. The Doctor's interactions with the other characters are filled with Colfer's trademark humor, but he serves up some particularly satisfying plot twists at the end.
For fans of Colfer's Artemis Fowl series, there's also a moment when the Doctor says something that made me believe that the Doctor may have visited Artemis' universe in the past. It's a blink and you'll miss it moment that made me happy the app has a "replay" button since I had to listen again to make sure (grin.)
