Clue in the Castle Tower: A Samantha Mystery

On a trip to England, Samantha and Nellie visit an ancient manor house - next to a castle that's rumored to be haunted. The visit turns spooky when the girls see odd and eerie lights in the castle tower at night . . . and learn that valuable books are disappearing from the manor's library. Can the girls find out who - or what - is behind the strange happenings? Includes an illustrated "Looking Back" essay about Americans traveling abroad at the turn of the last century.
