Biography
In 1851, Nathaniel became the latest victim of a spate of burglaries, all of scientists homes. The day after the burglary, he met the Seventh Doctor. He was persuaded to assist the Doctor with his investigation into the robberies and a series of grisly murders. They discovered a crashed spaceship under the docks that belonged to the Klathi. Alongside a Joebb, the enemy of the Klathi, Nathaniel and the Doctor stopped the Klathi from stealing a crystal from the Great Exhibition of the Crystal Palace to repair his ship and escape Earth as the ship's departure using the crystal would destroy London.
