Gerrard

was an avatar used by the shared collective consciousness of the city of Hisk to try to pry out the First Doctor's and Vicki's weaknesses while they were rewriting this consciousness. It pretended to be human detective Gerrard from 20th century Britain interviewing Ian Chesterton about the disappearance of him, Barbara Wright and Susan Foreman. (AUDIO: The Sleeping City)
