The Aldens are on a cruise in the Caribbean! No sooner has the cruise begun than things start to go wrong. The ship's radio breaks. It appears someone has fallen overboard --- but it turns out to be a false alarm. And then there's engine trouble! Is someone deliberately tampering with the ship? It's a mystery --- good thing the Boxcar Children are on board!
Someone is trying to keep Max Greene from inheriting his great aunt's estate.
Gertrude Chandler Warner was born in 1890 in Putnam, Connecticut, where she taught school and wrote The Boxcar Children because she had often imagined how delightful it would be to live in a caboose or freight car. Encouraged by the book's success, she went on to write eighteen more stories about the Alden children.
