Hey, everybody, it's me, Josh. And for this week's select, I've chosen our episode on the Flannan isle mystery from November 2021. This is one of those rare instances of a missing person's unsolved mystery disappearance case where the people weren't murdered. Well, almost certainly weren't murdered. That is one theory, but it's a lesser theory. And isn't that refreshing? I hope you enjoy this one. Even if you've heard it before. I can attest it's still good. Again, enjoy.

Hey, and welcome to the podcast. I'm Josh Clark, and there's Charles W. Chuck Bryant over there, and Jerry's out here, too. So since the gang's all here, the three of us alone on a deserted isle, stuff you should know.

Chuck Bryant (2:07)

Can I mention a couple of things here?

Josh Clark (2:08)

I think you should.

Chuck Bryant (2:10)

I want to pre apologize to our Scottish listeners whom we love. We toured in Scotland, had a great time, one of our best live shows in the beautiful city of Edinburgh. Yes, wonderful people love the Scots, but we are going to butcher some of these names. And I apologize ahead of time.

Summary

Stuff You Should Know: Selects – The Flannan Isles Mystery

Hosts: Josh Clark & Charles W. "Chuck" Bryant
Date: August 23, 2025

Episode Overview

Josh and Chuck revisit the haunting and unsolved disappearance of three lighthouse keepers from the Flannan Isles Lighthouse in 1900—a mystery that's persisted for over a century. The episode delves into historical records, debunks myths and fictional embellishments, and explores theories both mundane and supernatural. True to their style, Josh and Chuck bring humor, curiosity, and depth to re-examining one of maritime history's most notorious vanishings.

Key Discussion Points & Insights

Setting the Scene: The Flannan Isles & Lighthouse Life

Location & Geographical Challenges
- The Flannan Isles are a remote, windswept archipelago off northwest Scotland in the Outer Hebrides, notorious for treacherous seas and sheer, rocky cliffs.
- The Flannan Isles Lighthouse sits atop Island Moor, perched 200 ft above sea level—an area so exposed it’s near the famed "Butt of Lewis," the UK's windiest spot.
  - Josh (05:21): "The Butt of Lewis... it's the windiest part."
- Only the lighthouse keepers and some sheep reside on Island Moor. The “locals” (sheep owners) never stay overnight due to rumors of the island’s eerie quality.
Lighthouse Operations & Keeper Roles
- Run by the Northern Lighthouse Board since the late 18th century, lighthouse keeping was a respected profession—not the refuge of misanthropes as movies often portray.
  - Josh (09:47): "Lighthouse keepers are very frequently portrayed as weirdos... that's not the case. At least not in Scotland."
- Teams typically consisted of a principal keeper, an assistant or two, and an "occasional keeper" who worked rotating shifts due to difficult travel to the island.
- Falling asleep on duty was incredibly rare, illustrating the seriousness of the profession.
  - Josh (10:02): "Out of 2.75 million lighthouse nights in Scotland over fifty years, only 15 found a keeper asleep on duty."

The Disappearance: December 1900

The Lighthouse Keepers
- James Ducat: Principal Keeper
- Thomas Marshall: Second Assistant
- Donald MacArthur: Occasional Keeper, filling in for the first assistant (William Ross) who was on sick leave
Timeline of Events
- December 15, 1900: The transatlantic steamer Archter passes Flannan Isles and notes the lighthouse light is out—an uncommon and concerning sight.
- December 26, 1900 (Boxing Day): The relief vessel Hesperus arrives with supplies and a replacement keeper (Joseph Moore). No greeting from shore, flag is down, no response to horn blasts or flares.
  - Josh (23:10): "No one gets that steam shack going... they're like, alright, we have to go on land and figure this out."
- Discovery
  - Moore climbs 160 steps to the lighthouse; finds everything in meticulous order: beds made, meal finished, clock stopped, records up to date until Dec 15, oil ready.
  - Two sets of oilskins (rain gear) are gone, but one remains, implying at least one man went outside in haste, possibly unprepared.

Sifting Fact from Fiction: Mythmaking and the Real Record

Fictionalized Logbooks & Poems
- Over time, fabricated stories emerged: logbook entries describing horrifying storms, keepers weeping or mute, an untouched meal, and a toppled chair—none of which matched primary evidence.
  - Chuck (29:50): "It's still pretty creepy. The log entries in the fake log entries... 'storms I've never seen before in 20 years'... 'Ducat struck mute,' 'MacArthur weeping'—all fabricated."
  - Josh (31:05): "Mike Dash made mincemeat out of it... logbooks were not diaries."
- Wilfred Wilson Gibson's 1912 poem added unsettling embellishments (untouched meal, starving canary) that were subsequently uncritically repeated.
  - Chuck (31:21): "These are all the things... would have made this a different story, but everything was really just fine."
- Investigative Journalist Mike Dash established that these details were myth, not part of the original accounts.
Primary Evidence (Based on contemporary reports)
- The keepers’ home was tidy; crucially, only two oilskins missing, supporting the theory not all men went outside prepared.
- Severe storm evidence: a 2,000 lb stone displaced, iron railings twisted, a storage box shattered and contents gone, grass torn up 30 ft from cliff edge—indicating truly extraordinary wave action.

Theories: Rational and Paranormal

Plausible Explanations

Storm/Accident Theory (Mainstream View)
- Probably two men (Ducat & Marshall) ventured out to secure equipment or investigate storm damage. MacArthur, left inside, rushed out to aid them—possibly without his oilskins, indicating haste.
- A "rogue wave" (or two successive waves) swept all three men away in quick succession.
  - Josh (48:26): "That supposes something really amazing, Chuck... at least one swept away by a freak wave, the second goes for help, a second wave gets the last two."
  - Chuck (47:44): "MacArthur... had to leave quickly, which would explain why they had their rain gear on and MacArthur didn't."
- Later lighthouse keeper Robert Aldebert (1950s) observed waves so large their spray reached 200–300 ft up—confirming such freak events were possible.
  - Chuck (51:32): "He said... sea spray from some waves at the very top... so it's very possible a big wave could come through and reach these heights."
- Some storm damage evidence may even have occurred after the disappearance, during a later storm on December 20.
Wind Theory
- Originally floated, but discounted: winds were westerly (would have blown men inland), and keepers would likely have known how to protect themselves.

Other (Less Plausible) Theories

Murder or Fight
- MacArthur, known as a "hothead," possibly fought and killed fellow keepers, then jumped—or all three tumbled off the cliffs in a struggle.
  - No evidence supports any violence or disturbance; no signs of struggle inside or outside.
Paranormal/Supernatural Theories
- Kelpie (Water spirit) legend: Outer Hebrides "Kelpies" dragged them away. Rejected for being local folklore (and for dwelling in freshwater lochs vs sea).
- St. Flannan Sacrifice: Pagans sacrificed people here; the gods mistook lighthouse keepers for offerings.
  - Josh (45:16): "...the idea that the gods mistook the lighthouse keepers as a human sacrifice and that's what happened to him. I love that one."
- Tiny People Legend: The island was once home to a race of tiny prehistoric people—another fanciful explanation based on dubious ruins and folklore.

Notable Quotes & Memorable Moments

On Meticulousness of the Job:
- Josh (10:36): "Out of 2.75 million lighthouse nights in Scotland over fifty years, only 15 found a keeper asleep on duty."
Accidental Humor about the “Butt of Lewis”:
- Chuck (05:24): "The Butt of Lewis is the windiest island."
- Josh (05:25): "But Lewis is a nearby island... and it’s the windiest part."
Disappointment Over Fictional Embellishments:
- Chuck (29:50): "It's still pretty creepy. The log entries in the fake log entries..."
- Josh (31:05): "Mike Dash made mincemeat out of it... logbooks were not diaries."
On Rogue Waves:
- Josh (49:49): "That’s the only way that could happen... it would have had to have been two successive freak waves that cleared all three."
On Paranormal Theories:
- Chuck (44:12): "Kelpies are not seaside dwellers. They are inland at the lochs."

Conclusion

The Flannan Isles Mystery remains unsolved, shrouded in both historical fact and fanciful fiction. The most plausible answer is a tragic intersection of bad weather, bad luck, and human vulnerability in a perilous place—none of which has ever been proven conclusively due to the absence of physical remains. Josh and Chuck combine humor, skepticism, and historical rigor to cut through the myths and make sense of the tragedy, all while maintaining reverence for the romance and spookiness of unsolved mysteries.
