(From the publisher):
Someone is building a large, fancy house down the street from the Aldens'—a house shielded by a tall stone wall. The only way to approach the house is through an iron gate decorated with huge black widow spiders! Benny is certain the new neighbors must be hiding something...but what could it be? The Boxcar children are determined to investigate.
