Synopsis:
On their way to a New England hotel Ralph and Sue Dibny spot an old Victorian mansion. When they inquire about the mansion, the hotel manager tells them that it burned to the ground a year ago. The Elongated Man investigates the mystery and finds that crooks have created an inflatable mansion that they inflate on foggy nights. They are trying to coerce the butler of the former mansion owner into remembering where many of the art treasures that were taken from the house before it burned down are currently hidden. The butler leads them to the paintings, but the Elongated Man stops the crooks from stealing them. The confused butler then gets a job at the hotel.
