Tiana, Mackenzie, and Harlow have arrived at their high school to find it transformed for Halloween. The staff have built the most immersive Haunted House and the girls are informed their phones have a game to play. It’s all great fun, until Tiana steps into a classroom and finds a real witch’s hut in place of student desks. Her friends can’t see it, but their teacher is a witch! Professor Polter was originally published in the anthology Hauntings.
