Walter Pritchard

Walter Pritchard was a professor working in the British Museum in 1963.

While working as an assistant to Pritchard, Helen Sinclair met the Eighth Doctor and Liv Chenka who were in search of a temporal anomaly related to the Eleven. Joining them whilst they investigated a collection of artefacts featuring the Red Lady, she became involved in a mystery involving extra-terrestrial elements. Not having seen any of the artefacts featuring the entity, Helen was unaffected by her influence, and was able to help prevent the Doctor and Liv from succumbing to her effects.

After they defeated the Red Lady and the artefacts were "disposed of," Pritchard dismissed Helen from her position and threatened with being reported for the police, Pritchard being suspicious that she was behind their theft. Impressed by her help, the Doctor offered her the chance to join him in the TARDIS, which she accepted. (AUDIO: The Red Lady)
