Chapter 1: Mr Sherlock Holmes
BY Dr Joseph Bell

It is not entirely a bad sign of this weary, worn-out century that in this, its last decade, even the petty street-bred people are beginning, as the nurses say, to take notice. An insatiable and generally prurient curiosity as to the doings of the class immediately above us is pandered to by the society journals, and encouraged even by the daily newspapers. Such information is valueless intellectually, and tends to moral degradation; it exercises none of the senses, and pauperises the imagination. Celebrities at home, illustrated interviews, society scandal on all levels merely titillate the itching ear of the gossip. Memoirs, recollections, anecdotes of the Bar or of the Academy are much more interesting, and may be valuable as throwing sidelights on history, but still only amuse and help to kill the time of which we forget the value. But in the last few years there has been a distinct demand for books which, to a certain poor extent, encourage thought and stimulate observation. The whole Gamekeeper at Home series and its imitations opened the eyes of town dwellers, who had forgotten or never known White of Selborne, to the delightful sights and sounds that were the harvest of the open eye and ear. Something of the same interest is given to the "crowded city's horrible street" by the suggestions of crime and romance, of curiosity and its gratification, which we find written with more or less cleverness in the enormous mass of so-called detective literature under which the press groans. Every bookstall has its shilling shocker, and every magazine which aims at a circulation must have its mystery of robbery or murder. Most of these are poor enough stuff; complicated plots, which can be discounted in the first chapter, extraordinary coincidences, preternaturally gifted detectives, who make discoveries more or less useless by flashes of insight which no one else can understand, become wearisome in their sameness, and the interest, such as its is, centres only in the results and not in the methods. We may admire Lecocq, but we do not see ourselves in his shoes. Dr Conan Doyle has made a well-deserved success for his detective stories, and made the name of his hero beloved by the boys of this country by the marvellous cleverness of his method. He shows how easy it is, if only you can observe, to find out a great deal as to the works and ways of your innocent and unconscious friends, and, by an extension of the same method, to baffle the criminal and lay bare the manner of his crime. There is nothing new under the sun: Voltaire taught us the method of Zadig, and every good teacher of medicine or surgery exemplifies every day in his teaching and practice the method and its results. The precise and intelligent recognition and appreciation of minor differences is the real essential factor in all successful medical diagnosis. Carried into ordinary life, granted the presence of an insatiable curiosity and fairly acute senses, you have Sherlock Holmes as he astonishes his somewhat dense friend Watson; carried out in a specialised training, you have Sherlock Holmes the skilled detective.

Dr Conan Doyle's education as a student of medicine taught him how to observe, and his practice, both as a general practitioner and a specialist, has been a splendid training for a man such as he is, gifted with eyes, memory, and imagination. Eyes and ears which can see and hear, memory to record at once and to recall at pleasure the impressions of the senses, and an imagination capable of weaving a theory or piecing together a broken chain, or unravelling a tangled clue, such are implements of his trade to a successful diagnostician. If in addition the doctor is also a born story-teller, than it is a mere matter of choice whether he writes detective stories or keeps his strength for a great historical romance as is the White Company. Syme, one of the greatest teachers of surgical diagnosis that ever lived, had a favourite illustration which, as a tradition of his school, has made a mark on Dr Conan Doyle's method, "Try to learn the features of a disease or injury as precisely as you know the features, the gait, the tricks of manner of your most intimate friend." Him, even in a crowd, you can recognise at once; it may be a crowd of men dressed alike, and each having his complement of eyes, nose, hair, and limbs; in every essential they resemble each other, only in trifles do they differ; and yet, by knowing these trifles well you make your diagnosis or recognition with ease. So it is with disease of mind or body or morals. Racial peculiarities, hereditary tricks of manner, accent, occupation or the want of it, education, environment of all kinds, by their little trivial impressions gradually mould or carve the individual, and leave fingermarks or chisel scores which the expert can recognise. The great broad characteristics which at a glance can be recognised as indicative of heart disease or consumption, chronic drunkenness or long-continued loss of blood, are the common property of the veriest tyro in medicine, while to masters of their art there are myriads of signs eloquent and instructive, but which need the educated eye to detect. A fair sized and valuable book has lately been written on the one symptom, the pulse; to any one but a trained physician it seems as much an absurdity as is Sherlock Holmes' immortal treatise on the one hundred and fourteen varieties of tobacco ash: The greatest stride that has been made of late years in preventive and diagnostic medicine consists in the recognition and differentiation by bacteriological research of those minute organisms which disseminate cholera and fever, tubercle and anthrax. The importance of the infinitely little is incalculable. Poison a well at Mecca with the cholera bacillus, and the holy water which the pilgrims carry off in their bottles will infect a continent, and the rags of the victims of the plague will terrify every seaport in Christendom.

Trained as he has been to notice and appreciate minute detail, Dr Doyle saw how he could interest his intelligent readers by taking them into his confidence, and showing his mode of working. He created a shrewd, quick-sighted inquisitive man, half doctor, half virtuoso, with plenty of spare time, a retentive memory, and perhaps with the best gift of all—the power of unloading the mind of all the burden of trying to remember unnecessary details. Holmes tells Watson: "A man should keep his little brain-attic stocked with all the furniture that that he is likely to use, as the rest he can put away in the lumber-room of his library, where he can get it if he wants it." But to him the petty results of environment, the sign-manuals of labour, the stains of trade, the incidents of travel, have living interest, as they tend to satisfy an insatiable, almost inhuman, because impersonal curiosity. He puts the man in the position of an amateur, and therefore irresponsible, detective, who is consulted in all sorts of cases, and then he lets us see how he works. He makes him explain to the good Watson the trivial, or apparently trivial, links in his chain of evidence. These are at once so obvious when explained, and so easy, once you know them, that the ingenuous reader at once feels, and says to himself, I also could do this; life is not so dull after all; I will keep my eyes open, and find out things. The gold watch, with its scratched keyhole and pawn-brokers' marks, told such an easy tale about Watson's brother. The dusty old billy-cock hat revealed that its master had taken to drinking some years ago, and had got his hair cut yesterday. The tiny thorn-prick and fearsome footmark of the thing that was neither a child nor a monkey enabled Holmes to identify and capture the Andaman Islander. Yet, after all, you say there is nothing wonderful; we could all do the same.

The experienced physician and the trained surgeon every day, in their examinations of the humblest patient, have to go through a similar process of reasoning, quick or slow according to the personal equations of each, almost automatic in the experienced man, laboured and often erratic in the tyro, yet requiring just the same simple requisites, senses to notice facts, and education and intelligence to apply them. Mere acuteness of the senses is not enough. Your Indian tracker will tell you that the footprint on the leaves was not a redskin's, but a paleface's, because it marked a shoe-print, but it needs an expert in shoe-leather to tell where that shoe was made. A sharp-eyed detective may notice the thumb-mark of a grimy or bloody hand on the velvet or the mirror, but it needs all the scientific knowledge of a Galton to render the ridges and furrows of the stain visible and permanent, and then to identify by their sign-manual the suspected thief or murderer. Sherlock Holmes has acute senses and the special education and information that make these valuable; and he can afford to let us into the secrets of his method. But in addition to the creation of his hero, Dr Conan Doyle in this remarkable series of stories has proved himself a born story-teller. He has had the wit to devise excellent plots, interesting complications; he tells them in honest Saxon-English with directness and pith; and above all his other merits, his stories are absolutely free from padding. He knows how delicious brevity is, how everything tends to be too long, and he has given us stories that we can read at a sitting between dinner and coffee, and we have not a chance to forget the beginning before we reach the end. The ordinary detective story, from Gaboriau or Boisgobey down to the latest shocker, really needs an effort of memory quite misplaced to keep the circumstances of the crimes and all the wrong scents of the various meddlers before the wearied reader. Dr Doyle never gives you a chance to forget an incident or miss a point.
