When Quinn's new neighbor, Vaughn Taylor, told him that the kids in his class at school said the house at the end their road was haunted, Quinn just laughed. Quinn had ridden his bike down to the house many times and, while it was old, falling apart and spooky looking, he assured Vaughn that the place was certainly not haunted. To prove it, one Friday evening after school, Quinn, Vaughn, Reggie and Demian took the one-mile bike ride to the end of their road and found out that maybe Vaughn's classmates were correct. By the time they'd raced home, they were both frightened out of their wits. "I told you it was haunted," Vaughn said. Quinn Higgins didn't know what to make of their weird experience, but he was determined to get to the bottom of The Case of the Haunted House.
