The Marie Celeste was a merchant ship found floating in the Atlantic Ocean in December 1872 with nobody on board. The ship was in good shape, had plenty of food and water, and the crew’s personal belongings were still on board. Nobody from the ship was ever heard from again.
The mystery has been written about in several works of both non-fiction and fiction, including a short story by Arthur Conan Doyle which you can read online. It is even the subject of a computer game you can try out in your browser.
This Sunday Magazine article gives one theory for the ship’s disappearance, but if the mystery intrigues you, check out the Wikipedia entry for a lot more information, and the website maryceleste.net.
