The Case

A Locked Lighthouse. Three Men Gone.

On 26 December 1900, a relief vessel reached a lighthouse on a bare Atlantic island called . No flag flew. No keeper waited. Inside, the lamp was trimmed and the beds were unmade — but James Ducat, Thomas Marshall and Donald McArthur were gone.

Their bodies were never found. The death register, filed in February 1901, recorded just two words for cause: . A century of retellings then buried the facts under invented log entries and an uneaten meal that were never in the record at all.

The full account — every document, every debunked myth, every theory weighed against the three surviving primary sources — is in The Keepers Who Vanished, Book Four of The Unlucky Thirteen.

What's your theory?

A freak wave up the west gully. Three men caught on the landing at once, against the rules. A sea serpent, a spy, a ghost — the stories the record cannot support. The lamp still turns. The rock still keeps its answer.
