The novel “Plague City” by Jonathan Morris was published for the first time in 2017.

The Tardis materializes in Edinburgh, in 1645. When the Twelfth Doctor, Bill Potts, and Nardole go out to explore the surroundings, they get stopped by the guards who ensure compliance with the curfew established to contain the plague that has struck the city. The travelers split up when they run and see various aspects of the dire situation.

The Doctor and Nardole meet Thomas and Isobel, who recently lost their daughter Catherine to the plague. They discover that the Night Doctor visits homes when one of the inhabitants is about to die and is dressed as a plague doctor. The spirits of the dead return to visit their relatives and the travelers see them too.
