Rook (Hunters of Earth)

Colonel Rook was a military officer in the Second World War and a teacher at Coal Hill School in 1963.

He wanted to know who Susan Foreman was, and asked his nephew Cedric Chivers to spy on her. 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. (AUDIO: Hunters of Earth)
