The Mysterious Caravan (Hardy Boys, Bk. 54)

When the Hardy Boys take a winter vacation in Jamaica, Joe finds an ancient bronze death mask washed up near their beach house during a violent storm. Did it come from a Portuguese galleon wrecked offshore centuries ago? Why are three treasure hunters determined to snatch the relic at any risk? Is it because of the cryptic Arabic words concealed in the mask? Helping the Hardys and their friends in this bizarre mystery is William, A Jamaican boy, who flies to New York with startling news, only to be intercepted and held for ransom--the death mask! How Frank and Joe rescue William, plunge into their father's airline-ticket theft case, and fly into a maze of danger in Africa will hold Hardy Boys fans breathless to the last page of The Mysterious Caravan.
