The Manning House Saga continues where Secrets Under the Apple Tree leaves off when the boys ask about a haunted house. Now, Cory Albright and Bobby Davidson set out to investigate a real mystery. This time, instead of an old strong box, they are asking questions about a haunted house near the center of town. This time, the mystery is not something they believe their fathers buried in the dirt under an apple tree years ago. The house is the largest mansion in town and protected by a security gate. Rumor has it the house is haunted because by all appearances its empty, or is it?
