Poe's got enduring relevance for our era of unreliable narrations. His 1845 short story 'The System of Dr. Tarr and Prof. Fether' – set in a private mental institution – popularized the adage, "Believe nothing you hear, and only one half that you see."
In our era of generative AI, that needs a small update – "Believe nothing you see or hear, and only half of that over a strongly-authenticated channel from a reliable source". But the story's themes of communities-of-mental-illness and blurred boundaries between doctor and patient (or between therapy and enablement) still resonate.
There's an old TV movie adaptation of this that I saw when I was about 8, long before I had developed a taste for reading.
I would have sworn it was Disney, because I recall seeing it at least twice and walking away from a decision to watch it another time or two, and that was very on-brand for Disney at the time. However, Wikipedia is telling me that it was made by ABC in 1980 and starred Anthony Michael Hall. I suppose ABC must have done reruns during the summer.
Donald Menzel, a Harvard astronomer/astrophysicist, was also inspired by The Gold-Bug. Among other things, he helped the Navy organize a secret cryptanalysis-training class at women's colleges during WW2.
See the paper "The Cryptologic Contributions of Dr. Donald Menzel" by Craig Bauer and John Ulrich.
I thought it would be interesting to see if the local AI I use for quick question and answer stuff could crack the code.
I use Deepseek V4 flash 0731 Q8 quantisation from unsolth with reasoning turned off on a local server for quick easy tasks. Note I use another model locally for harder tasks that need reasoning.
I was a bit dissappointed that it knew it was Poe's cypher so didn't need to even try to crack the code.
I saw a different video about cracking the Enigma recently and learned something new about it. It's basically a Rube Goldberg substitution cypher - each character is encoded in a cypher and then advanced to another cypher. There were two consequences of that.
'A' would never map to 'A'. So any message with a known plaintext of local weather conditions, or like in The Imitation Game, "Heil Hitler", you could test the plain text at each position of the encoded message and know that the message did not contain the known plaintext because none of the letters could match in sequence. If 'ei' or 'e_____t' existed in the cipher then the input could not contain the same. So selection of the candidate messages for cracking first culled any messages that definitely did not contain the known plain text.
Additionally, the breadboard part of the cipher was static throughout any given day, and reciprocal. That is, if A was currently mapped to B, then B also mapped to A, which is not usually the case with Caesar. That caused the breadboard stages between the wheels to cancel each other out, because A at the output of wheel 1 would change to B and then back to A for the input to wheel 2. That dropped the number of substitutions per character on the 3 wheel Enigma from 9 to 5, and thus reducing the exponent of the problem space, and the complexity of The Bombe.
This is one of my favourite Edgar Allan Poe stories. The cipher is just a simple monoalphabetic substitution one based on frequency analysis.
The same idea was "reused" by Arthur Conan Doyle in his story "The Adventure of the Dancing Men" where he used pictures of dancing men for his cipher text.
Note that Conan Doyle indirectly acknowledged Poe's influence (via his character Auguste Dupin) on Sherlock Holmes in "A Study in Scarlet".
Poe wrote three stories starring his detective Auguste Dupin all of which are fantastic. They are "The Murders in the Rue Morgue", "The Mystery of Marie Roget" and "The Purloined Letter". They are a must-read for all fans of detective fiction. Folks who have read Sherlock Holmes can see how much he was influenced by Dupin. The stories often have some close/clever observations/reasonings which given Poe's style of writing are a delight to read.
For example the opening paragraph of "The Murders in the Rue Morgue" reads;
THE mental features discoursed of as the analytical, are, in themselves, but little susceptible of analysis. We appreciate them only in their effects. We know of them, among other things, that they are always to their possessor, when inordinately possessed, a source of the liveliest enjoyment. As the strong man exults in his physical ability, delighting in such exercises as call his muscles into action, so glories the analyst in that moral activity which disentangles. He derives pleasure from even the most trivial occupations bringing his talent into play. He is fond of enigmas, of conundrums, of hieroglyphics; exhibiting in his solutions of each a degree of acumen which appears to the ordinary apprehension præternatural. His results, brought about by the very soul and essence of method, have, in truth, the whole air of intuition.
The essence of why some people love solving problems!
Poe is awesome. If you're near Charleston, it's worth visiting Sullivan's Island- try to find the tree.
When Poe writes about murder, it's often first person point of view of the murderer- I find it more disturbing than later horror writers like HP Lovecraft or Steven King.
The Cask of Amontillado is great for that. And the classic poem The Raven describes existential dread so well.
I found with King the scarier aspects were the more mundane and psychological parts of his writing. I also found in some cases the adaptations to be better in some ways -- The Shawshank Redemption adaptation is great. And the poem in the TV adaptation of The Tommy Knockers felt more impactful than the one in the book.

Ha! Too smart for its own good. Is it possible to ask it to pretend it hadn't seen the example before?
I just tried that and it went down a rabbit hole for about 20 minutes before using "the exact method from Poe's story". So basically cheated :)
Also if you haven't seen it, https://en.wikipedia.org/wiki/The_Gold_Bug_Variations by Richard Powers is an absolutely amazing fiction book that combines DNA, cryptography, and many more interesting concepts.
Also a song by The Alan Parsons Project, inspired by the same story: https://youtu.be/6aebUrI-WYQ
