The Message in the Hollow Oak by Carolyn Keene

5.0

Nancy jets off to New York and then Illinois to uncover a lost treasure near an excavation site. She is randomly trapped in an elevator upon her arrival in NY (which is never explained) but I guess we are meant to assume that this was the work of Kit. Aunt Eloise turns Nancy on to this mystery, and Ned’s female cousin just so happens to be on the dig site in Illinois where she needs to go. Serendipitous! Anyway, true to Nancy Drew fashion, there’s a couple of kidnappings, George takes a spill, and Nancy solves the intrigue that the adults just can’t seem to figure out.
