Something is haunting the Laingford Pioneer Village Park, a mysterious presence that seems determined to get Alan and his two friends in trouble. They are spending the tail-end of the summer working as costumed helpers at the historical site, and when things get weird, the Alan Nearing detective agency starts investigating. Is the poltergeist just a prankster, or are there sinister forces at work?
