The Mystery at the Moss-Covered Mansion

Nancy Drew embarks on two thrilling mysteries in Florida. In the first, she investigates the disappearance of valuable jewels first discovered by a Spanish captain on a sunken ship at the behest of Mrs. Horton. In the second, Nancy comes to the aid of a family friend, Mr. Billington, who has been falsely accused of sending a truck loaded with explosive oranges into the Space Center complex at Cape Kennedy. As Nancy delves deeper into the case, she becomes suspicious of a nearby spooky mansion with fierce African wild animals, and soon uncovers a sinister plot threatening the U.S. space program.
