FILE 003 | The Lighthouse Keepers Who Vanished Without a Trace | The Flannan Isles Mystery

Three lighthouse keepers. One remote island. A lighthouse still operating normally... but not a single person left alive to explain what happened. In December 1900, a relief crew arrived at the Flannan Isles Lighthouse off the coast of Scotland. The lamp was still burning. Meals were left unfinished. Personal belongings remained inside. But the three keepers had vanished. No bodies. No witnesses. No clear explanation. More than a century later, the disappearance of James Ducat, Thomas Marshall, and Donald MacArthur remains one of history's most enduring unsolved maritime mysteries. This episode reconstructs the final known events, examines the official investigation, and explores the theories that continue to divide historians to this day.
