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!
