Which Sherlock Holmes Story Should You Read First? Doyle's Own Ranking of the Twelve AdventuresTwelve stories, no required order, and a reading-order genre that answers a question nobody asked. Doyle published a ranking of his own in 1927, and four of his top twelve are in this one book.
Every Sherlock Holmes Adaptation, Ranked for Faithfulness: Granada, BBC, Downey, ElementaryGuinness counted 254 screen Sherlock Holmeses back in 2012. Ask which one is best and you get a fight; ask which is closest to what Doyle actually wrote and the answer has been the same for forty years.
Did Arthur Conan Doyle Hate Sherlock Holmes? Why He Killed Him, and Why He Brought Him BackDoyle sent his detective over a waterfall in 1893 and spent the next decade being asked to undo it. The letter to his mother, the cancellation figure nobody can source, and the two real criminal cases he worked himself.
Irene Adler on Screen vs the Book: What the BBC and Elementary InventedOne story, under nine thousand words, and she is out of the country by the end of it. Everything else you have seen Irene Adler do — the romance, the phone, the reveal that she is Moriarty — was written for television.
“Data! Data! Data!” What the Sherlock Holmes Line Means, and the Word Everyone MisquotesThe line turns up on conference slides and in data-quality decks, almost always one word wrong. Doyle put it in the last of the twelve Adventures, in the mouth of a man who is worried about a client he could not talk out of a bad decision.
Who's Who in The Adventures of Sherlock Holmes: Every Character in the Twelve StoriesAsk anyone to name the cast and you get Holmes, Watson, Mrs Hudson, Lestrade, Moriarty and Mycroft. Four of those six are in the 1892 collection. The other two appear in it exactly zero times.
The one Sherlock Holmes case he loses — and the woman who beat him (2026)You picture Sherlock Holmes as an unbeatable, unfeeling logic machine. But the very first story in the collection is the one he loses — to Irene Adler, a woman he underestimated. Afterward he keeps her photograph and calls her only “the woman.” The one time the machine loses is the most human he ever gets.
Dr. Watson isn't the bumbling sidekick — he's the blueprint every genius-and-friend duo copies (2026)You've been told Dr. Watson is the bumbling comic sidekick who fumbles while the genius thinks. Doyle wrote the opposite: a sharp ex-army surgeon, wounded in Afghanistan, who narrates almost every case — the reader's stand-in who keeps an impossible genius human. If you have one brilliant, difficult friend, you're already playing Watson, and it's more work than it looks.
“You see, but you do not observe”: Sherlock Holmes's two-move superpower (2026)It's eleven at night and he still hasn't texted back — and your brain has already written the whole story. Sherlock Holmes has a 130-year-old fix, and it's two moves, not one: notice before you narrate, and refuse to build the story until you have the data.
Sherlock Holmes's real problem isn't crime — it's boredom (2026)We remember the deductions. Doyle wrote a man who falls apart the moment there's no case to solve — black moods, cocaine, a restless mind that can't survive a quiet Saturday. Meet the patron saint of the always-needs-a-project mind.
