Rook (Hunters of Earth)

Colonel Rook was a military officer in the Second World War and a teacher at Coal Hill School. He wanted to know who Susan Foreman was. He asked Bernie what the First Doctor wanted from his shop. He tricked the Doctor into going into a warehouse, and wanted to use Susan's psychic abilities to help in a war. He was Cedric Chivers' uncle and asked him to spy on Susan. (AUDIO: Hunters of Earth)
