Professor Bailey was a fictional character from the Wraith World novels.
Professor Bailey and his students fought against Hank Carter. They wanted to make sure that Carter couldn't take down the barrier between the Wraith World and the Earth. Bailey also defeated the Wraith Warriors in the second Wraith World novel. He used a machine to trigger a minor earth quake. This earth quake caused the body of the Wraith Warriors to break down into individual worms which were picked up by crows. Sarah Jane Smith later used the same method to stop the Wraith Warriors in the human world. (AUDIO: Wraith World)
