The lighthouse was dark - it had not been lit for days, causing concern among passing ships. When Joseph Moore, the relief keeper, reached the lighthouse, he found it empty. The three keepers - Thomas Marshall, James Ducat, and Donald MacArthur - were gone. The clock had stopped. A meal lay untouched on the table. Two sets of oilskins were missing from their hooks. The third was still there. The three men were never found. The Flannan Isles mystery became one of the most famous disappearances in maritime history.
