The Phrase Holmes Never Said
Everyone knows Sherlock Holmes says "Elementary, my dear Watson." He doesn't. Not once, in any of the sixty stories Arthur Conan Doyle wrote. You don't have to take that on faith — the complete canon is loaded below, and you can search it yourself.
It is one of the most quoted lines in English, the verbal fingerprint of the world's most famous detective. It is also a thing that was never written. The search box below runs over the real, complete, public-domain text of the four Holmes novels and fifty-six short stories — every word Conan Doyle published about Holmes, about 3.7 million characters of it. Type the famous phrase and watch the counter.

in context
Search elementary, my dear Watson and you get zero. Search the two halves on their own and the canon fills with them: Holmes calls a deduction "elementary" eight times, and addresses his friend as "my dear Watson" eighty-six times. The words are everywhere. The sentence is nowhere. Doyle simply never welded them together.
What he actually says
The closest Holmes ever comes to the catchphrase is in "The Crooked Man" (1893). Watson has just cried "Excellent!" at a chain of deductions, and Holmes deflects:
"Elementary," said he. "It is one of those instances where the reasoner can produce an effect which seems remarkable to his neighbour, because the latter has missed the one little point which is the basis of the deduction." — The Memoirs of Sherlock Holmes, "The Crooked Man"
That single bare "Elementary" — addressed to Watson, but not naming him — is very likely the seed the later catchphrase grew from. And in "A Case of Identity" (1891) the two fatal words land in one sentence, in the wrong order, for a different purpose:
"All this is amusing, though rather elementary, but I must go back to business, Watson." — The Adventures of Sherlock Holmes, "A Case of Identity"
It is the only place in all sixty works where elementary and Watson share a sentence Holmes speaks — and it still isn't the phrase. (Search either word above to find these for yourself.)
So where did it come from?
If not Doyle, then who? The honest answer is that the line condensed — out of parody and the popular press around the turn of the century — rather than being coined by any one author. Two independent newspaper-archive investigations let us date its rise. The popular credit goes to the actor William Gillette, who wrote and starred in the hit 1899 stage play Sherlock Holmes — but the line appears in no published version of his script, so that attribution is a story we cannot verify, not a documented fact.

- 1901A parody in the Northampton Mercury runs "Elementary, my dear Potson" — the template already circulating as a joke.
- 1908The earliest known exact match in print: The Globe (London), 27 February — "Elementary, my dear Watson."
- 1915P. G. Wodehouse puts it in a famous book — Psmith, Journalist: "'Elementary, my dear Watson, elementary,' murmured Psmith." Often called the "first" use; in fact the newspapers beat him to it.
- 1929The first Holmes talkie, The Return of Sherlock Holmes, puts the line in Holmes's own spoken voice — and the phrase becomes permanent.
So the most Holmesian sentence in the language is a kind of collective forgery in reverse: not words falsely attributed to a fraud, but words the real author never wrote, attached so firmly to his character that the character now seems incomplete without them. The misquote is more famous than almost anything Holmes genuinely said.
The check
The corpus this page searches is the actual public-domain text of all four Holmes novels and fifty-six short stories, fetched from Project Gutenberg and stripped of its boilerplate (the same canon.json the search box loads). Counts, case-insensitive across the whole corpus: "elementary, my dear Watson" → 0; "elementary" → 8; "my dear Watson" → 86; "my dear fellow" → 43.
You can reproduce every number from a clean machine: research/elementary-watson/verify.mjs re-downloads the nine volumes, recounts, and fails loudly if the corpus ever drifts from these figures.
What is not asserted: that Gillette coined it (the line isn't in his script — flagged unverified above). The dated provenance entries come from two primary-source newspaper-archive trackers, cited below.
