A place, location, or high-occupancy vehicle (especially a ship) that is inexplicably deserted or abandoned. An allusion to the Mary Celeste, an American merchant brigantine that was discovered floating off the Azores Islands in 1872 with no one on board and still in seaworthy condition. (Note: The variant spelling of "Marie" is the more common usage for the idiomatic reference, likely due to its use in a story by Arthur Conan Doyle.) We came upon a house in the woods, empty as the Marie Celeste, but left otherwise untouched.
