Reading a ghost story on Christmas Eve was once as much a part of traditional Christmas celebrations as turkey, eggnog, and Santa Claus.

When he finds an abandoned duck punt on Christmas Eve, a hunter rows out into the marsh and comes across a shipwreck. He climbs aboard to explore—and finds himself trapped when a surge snaps the mooring line and his punt floats away. Sleep eludes him, and soon he discovers that he's not the only one trapped on the derelict ship.
