On Boxing Day, December 26th 1900, the lighthouse supply ship Hesperus arrived at the tiny island of Eilean Mor -- the largest of Flannan Islands off the northwestern coast of Scotland.  She was there to drop off food and supplies as well as relief keeper, Joseph Moore,  who was to begin his 6-week stint at the station.  But when repeated blasts of the horn and even a flare fired over the lighthouse failed to bring the keepers down to the dock, Captain Harvie became concerned.  So he sent Moore up to the lighthouse to discover why the men didn't come down to the landing to greet the ship.  Upon entering the living quarters, Moore found it deserted.   A thorough search of the island turned up few clues, but the bodies of the missing keepers were never found.  It was if James Ducat, Thomas Marshall and Donald McArthur had vanished into thin air.
