The exact words

““Excellent!” I cried. “Elementary,” said he.”Arthur Conan Doyle, “The Crooked Man,” The Strand Magazine (1893)
≈ ParaphraseThe idea is genuine, but the popular wording is not what was actually said or written.

What Holmes actually says

Arthur Conan Doyle wrote sixty Sherlock Holmes stories, four novels and fifty-six short stories, between 1887 and 1927. Readers who search them for the most famous line in detective fiction will not find it. Holmes never says “Elementary, my dear Watson.”

He comes close. In “The Crooked Man,” published in The Strand Magazine in 1893, Holmes makes one of his quick deductions about Watson’s daily life, and Watson exclaims, “Excellent!” Holmes replies with a single word: “Elementary.” Two lines earlier, in the same exchange, he had begun, “I have the advantage of knowing your habits, my dear Watson.” He uses “my dear Watson” in many other stories too, often with a touch of affectionate impatience. The two pieces were sitting a few lines apart, waiting for someone to join them.

Who joined them

The earliest known use of the full phrase comes from P. G. Wodehouse. In his 1915 comic novel Psmith, Journalist, the elegant Psmith solves a small puzzle and murmurs, “Elementary, my dear Watson, elementary,” a clear joke at Holmes’s expense. Parody often fixes a character’s voice better than the original, and this one stuck.

When Sherlock Holmes arrived in sound films, the phrase came with him. The 1929 film The Return of Sherlock Holmes used it, and the many films, radio plays and cartoons that followed turned it into Holmes’s catchphrase. By the middle of the century it was so familiar that most people assumed it came from the books.

How to use it

The phrase is now a standard joke for pointing out that something is obvious, and there is nothing wrong with using it that way. In writing about Holmes, though, avoid presenting it as Conan Doyle’s line. “The phrase Holmes never actually says” is a fun detail that shows you know the books.
