Sherlock Holmes Stole His Entire Vibe from Edgar Allan Poe (Then Insulted Him)

Imagine taking someone else's brilliant blueprint, building a massive pop-culture empire out of it, and then using your very first chapter to publicly trash-talk the guy who gave you the idea.\n\nThat is not the plot of a modern tech rivalry. That is precisely what happened in 1887 when Sir Arthur Conan Doyle introduced the world to Sherlock Holmes.\n\n## The French Detective Who Did It First\n\nLong before Baker Street had a house number, Edgar Allan Poe basically invented the modern detective story out of thin air. In 1841, Poe published The Murders in the Rue Morgue, introducing a character named C. Auguste Dupin.\n\nDupin wasn't a cop. He was a brilliant, slightly eccentric amateur who lived in Paris and solved baffling mysteries purely by using logical deduction. If that sounds familiar, wait until you look at his living situation. Dupin shared an apartment with a loyal, unnamed narrator who met him by chance at a library on Rue Montmartre and ended up paying their rent. Sound like a certain flatshare at 221B?\n\nPoe didn't just write a good mystery; he handed future authors a complete cheat code. He established every trope we still love today: the genius eccentric, the roomie narrator, the hopelessly baffled official police, and the concept of a locked-room mystery. In Poe's story The Purloined Letter, police spent weeks exhaustively dismantling furniture and probing walls with needles, completely missing the stolen document sitting right in plain sight on a mantelpiece. Dupin walked in and spotted it immediately.\n\n## Borrowing the Recipe (and the Roommate)\n\nDecades later, a young Arthur Conan Doyle was reading Poe's stories and taking extensive notes. In his 1924 autobiography, Doyle openly admitted that Dupin was one of his childhood heroes.\n\nWhen it came time to create his own detective, Doyle didn't hide his inspiration—he embraced it. He needed a grounded, reliable narrator to make Holmes's wild leaps of logic feel believable, so he created an educated man of action with a delightfully simple, unpretentious surname: Watson. Together, Holmes and Watson moved into a shared flat and began outsmarting the local police force, step for step following Poe's structural blueprint.\n\n## The Ultimate Victorian Roast\n\nHere is where the story gets delightfully petty.\n\nIn Doyle's debut Holmes novel, A Study in Scarlet, Watson tries to compliment Holmes by comparing his extraordinary analytical skills to Poe's famous detective, Dupin.\n\nYou might expect Holmes to smile modestly and express gratitude for the comparison. Instead, Holmes scoffs. He tells Watson that Dupin was a "very inferior fellow" who merely played at being clever. Holmes even snarks about Dupin's famous habit of staying silent for fifteen minutes before dropping a mind-reading observation on his friend, calling the whole thing "very showy and superficial."\n\nDoyle literally made his brand-new character roast his own real-life literary hero. It was the Victorian equivalent of dropping a diss track on your mentor.\n\n## The Otterly Interesting Part\n\nWhat makes this literary theft-and-shade routine so hilarious is that it actually worked. Doyle took Poe's genius structural formula, gave it a coat of foggy London paint, added a violin and a deerstalker hat, and created the most famous fictional character in history. Holmes' roast of Dupin didn't destroy Poe's legacy; it accidentally bound the two detectives together forever.\n\n## A Legacy of Cozy Tropes\n\nEvery time you watch a modern TV show featuring a socially awkward genius paired with a sensible sidekick who explains things to the audience, you are watching Edgar Allan Poe's 1841 brainchild at work. Doyle may have let Holmes throw shade from his armchair, but without Poe's groundwork, Baker Street might just be another ordinary street in London.\n\nSo here's to Dupin: the original eccentric roommate who solved crimes, lost his mail on a mantelpiece, and never quite got the credit he deserved.
