The Secret of the Mary Celeste

For three weeks now, you've been on the American brig "Dei Gratia" sailing the Atlantic to deliver a cargo of petroleum from New York to Gibraltar. Suddenly, somewhere between the Azores and Portugal, your crew spots a foreign ship under sail, heading directly towards you. Through a telescope, your captain identifies it as the famous ship "Mary Celeste". At first glance, everything seems to be in order. But, there's nobody to be seen onboard and the sails are oddly flapping in the wind. Among you sailors, the strangest theories are beginning to circulate. Did giant krakens snatch the crew off the ship, one by one? Are aliens responsible for their disappearance? Or were pirates behind it? Your captain decides to row towards the Mary Celeste with a rowboat and his bravest companions. At this point, not even the captain knows that you are dealing with one of the most mysterious events in maritime history.
