(From the publisher):
Henry, Jessie, Violet, and Benny are actors in a live mystery show being broadcast on an old-fashioned AM radio station. But that's not the only mystery the Boxcar children are part of—it's starting to look like the radio station is haunted! Why would a ghost want to sabotage a radio show? Can the Aldens save the radio station before its listeners are scared away?
