Impact: The Adventures of Sherlock Holmes

The Doctor Who Invented a Detective

Arthur Conan Doyle trained as a physician in Edinburgh, and the most important thing that education gave him was not medicine — it was a professor named Joseph Bell. Bell was famous among students for his uncanny ability to deduce a patient's occupation, history, and habits from nothing more than a careful glance. He would announce, before a word had been spoken, that a man had been a soldier in Barbados, or that a woman had recently taken up sewing. Doyle watched, took notes, and stored it all away.

When Doyle set up his own medical practice in Southsea in the early 1880s, patients were slow to arrive. He used the empty hours to write. Holmes first appeared in A Study in Scarlet in 1887 — published in a cheap annual, largely ignored, sold outright for twenty-five pounds. Doyle had no idea what he had made. He was a competent doctor with a gift for storytelling and absolutely no sense of which of his stories would last.

A Sensation in Monthly Installments

The Strand Magazine launched in 1891 with a mission to reach the new mass reading public — literate, middle-class Victorians who commuted by rail and wanted something gripping in a convenient format. The Holmes stories fit perfectly. Each story was self-contained, which meant you didn't need to have read the last issue to follow the current one. Circulation climbed sharply. Queues formed outside newsagents on publication day. Within months, Holmes was a household name.

What made the stories so immediately addictive was partly the formula and partly the voice. Watson is not a fool — that is a later misconception, mostly introduced by stage and screen adaptations. In the original stories, Watson is a capable, observant, warmly human narrator who functions as the reader's proxy: he sees everything Holmes sees and still can't quite believe what Holmes makes of it. The gap between what Watson notices and what Holmes deduces is where all the pleasure lives. It is a machine designed to produce satisfaction, and Doyle built it almost without trying.

What the Stories Are Actually About

On the surface, these are puzzle stories. Holmes receives a client, observes something extraordinary in the most ordinary details — the inside of a shoe scraped by six parallel cuts, a tan line that stops at the wrist, a callus in exactly the wrong place — and proceeds to unravel a mystery the police have either missed or given up on. The pleasures are real and reliable. But the deeper subject of the stories is something more interesting: the relationship between reason and emotion, and what it costs to be purely rational.

Doyle sets this up with extraordinary directness in the very first story of this collection. Watson describes Holmes as 'the most perfect reasoning and observing machine that the world has seen' — but then immediately introduces Irene Adler, the one person who has ever genuinely unsettled him. Holmes's position is that emotion is 'grit in a sensitive instrument.' And yet Adler, by being smarter than he expected, earns something from Holmes that no one else does: respect bordering on reverence. 'To Sherlock Holmes she is always the woman,' Watson writes. That line is still astonishing. It tells you everything about how tightly wound Holmes is, and exactly where the cracks are.

The stories are also, quietly, about class and visibility. Holmes notices servants, cab drivers, soldiers returned from abroad, shopgirls, landladies. Victorian society trained its respectable members not to look too closely at the people who kept the machinery running. Holmes looks at everyone with the same forensic attention. In story after story, the truth is hidden in plain sight among people no one thought to observe.

The Character Who Escaped His Author

By 1893, Doyle had had enough. He wrote to his mother that he was thinking of killing Holmes off, to free himself to write other things. Her response was reportedly: 'You won't!' He did anyway. At the Reichenbach Falls in 'The Final Problem,' Holmes and his nemesis Professor Moriarty plunge to their apparent deaths. Doyle was relieved. He went off to write historical fiction.

The public was inconsolable. Over twenty thousand people cancelled their Strand subscriptions. The outcry continued for years. In 1901, commercial pressure pushed Doyle into writing The Hound of the Baskervilles — set before Holmes's death, technically not a resurrection. But in 1903, he finally brought Holmes back from the dead in 'The Adventure of the Empty House,' offering the explanation that Holmes had not actually fallen after all. Doyle had created something he could not destroy. Holmes was already bigger than his author, and both of them knew it.

The Cultural Footprint

No fictional character has been portrayed on screen more times than Sherlock Holmes — the Guinness World Records has confirmed this, with over seventy actors playing the role in official productions. That number doesn't count parodies, pastiches, or the thousands of fan adaptations that predate the internet. Holmes has appeared in Soviet film serials, Japanese anime, a CBS procedural set in New York (Elementary), and the BBC's Sherlock, which updated him to the present day and made Benedict Cumberbatch briefly the most-discussed actor on the internet. Every version, however radical the update, keeps reaching back to the same source material.

Beyond direct adaptations, Holmes essentially founded the template that most detective fiction still follows. The brilliant, eccentric investigator with a more grounded companion. The genius who is socially impossible but morally indispensable. The method that treats observation as a kind of superpower. Agatha Christie's Hercule Poirot, Rex Stout's Nero Wolfe, House M.D. (the medical drama was openly modeled on Holmes — House even lives at 221B in his hospital), and countless others are all, in some sense, descendants. The form Doyle invented in these pages became the dominant popular fiction genre of the twentieth century.

There is also 221B Baker Street — an address that did not exist when Doyle invented it, because Baker Street at the time only ran to number 100. The street was eventually extended, and the building now numbered 221B houses the Sherlock Holmes Museum, which receives letters addressed to Holmes from around the world, many of them asking for help with real problems. The museum employs someone to answer them.

Reading It Now

What surprises modern readers most, coming to the original stories after a lifetime of adaptations, is how funny they are. Doyle had real comic timing. The moment in 'A Scandal in Bohemia' where Watson arrives at Baker Street and Holmes immediately announces — with characteristic precision — that Watson has gained not seven pounds but seven and a half, then graciously concedes 'seven' when Watson pushes back, is a small masterpiece of comic characterization. Holmes is not just brilliant; he is slightly insufferable about it, and Watson's long-suffering tolerance is the engine that makes the whole thing run.

The stories are also faster than people expect. Doyle wrote for magazine readers with limited patience and infinite other options. There is no fat here. The pacing of a good Holmes story is almost cinematic — a client arrives, Holmes observes, the case unfolds, the solution arrives in a rush. Reading one story takes twenty minutes. Reading all twelve in this collection is an evening well spent.

The question of whether these are 'literature' in the capital-L sense has never really been settled to anyone's satisfaction, and it no longer seems like the right question. What Doyle built in these pages was a character so vivid, a voice so precise, and a formula so satisfying that a hundred and thirty years of imitation has not worn it out. Holmes is still, in Watson's phrase, 'at work again' — in every new adaptation, every pastiche, every story that pits a brilliant loner against a world that doesn't quite understand how they see. That is not a small thing to have done.
