John Smith (Plague City)

Sir John Smith of Grothill was the Provost of Edinburgh in 1645.

He was infected with the plague and also had a Grief Leech attached to his stomach. The leech was removed by the Twelfth Doctor who then cured Smith with a tablet from the TARDIS.

He later led the people of Edinburgh in defeating the Grief Leeches with the help of the Doctor and his companions. (PROSE: Plague City'')
