He took up his usual position, sitting cross-legged and silent at the head of the bed, his gaze concentrated upon whichever guard sat at the table in the far end of the cell. The man who kept watch was beyond the range of Holmes' capable and efficient fists but never beyond the reach of those unblinking and penetrating eyes.
THE CORPORAL OF HORSE
There were two men who took it in turns to watch him as he woke or slept. They had divided their duty so that each kept vigil for two days and then two nights alternately. At night they slept in the wooden chair, beyond the range of the chain that held his anklet.
Holmes gathered that the name of the first man was Crellin. He was tall with a lantern jaw, dark hair piled on his head like an old-fashioned courtier's wig, and a look of brutalised cunning. A movement of his mouth seemed at first to promise a skeptical smile. It was no more than a misalignment of the lips. Crellin might laugh, but he never smiled.
The other man was more slightly built, his complexion so deeply reddened by the sun, the skin so tight and shiny on the bones of his face, that he looked as if he had been boiled. Holmes heard him referred to as Mac. At a glance, this smaller man seemed the less pugnacious of the two. Holmes decided to put the matter to the test. It was not necessary that he should defeat all his captors. One might be enough.
He had once remarked that from a single drop of water the logician could infer the existence of the Niagara Falls or the Atlantic Ocean without ever having seen either. It now seemed that by knowing the nickname of one jailer Sherlock Holmes proposed to find a path to freedom from the condemned cell of the most closely guarded prison in the world. The thing was so utterly impossible that not even Henry Milverton would feel that he needed to protect himself against it.
From the moment the warder who was his daytime keeper entered until the man left at dark, Holmes was the hawkfaced, cross-legged idol whose eyes drilled into the guard's mind and thoughts, scattering them like ninepins. I had seen him confront a practised trickster or a hardened scoundrel and with this same unblinking stare fix the unfortunate wretch for perhaps thirty seconds. None of them ever endured it longer. Some, like Professor Moriarty, tried to turn it to laughter, but the flame scorched them. To be burnt like an insect by such unblinking and brilliant fire for an entire day would beggar description! On the first occasion, Crellin glared back at the steady glitter of those eyes. He growled a threat, as if that settled the matter, and looked away. The eyes gave him no rest. Chained as he was, Sherlock Holmes pursued the sullen bully into the dark shadows of his mean soul.
Yet it was a waste of time. Crellin might squirm, but he would not squeal. He had taken Milverton's shilling and must do as he was told. After an hour he growled threats of coming to do for Holmes with his heavy fists, but he never dared to set foot within reach of the prisoner's chain.
Mac was a different case. The line of the mouth was far more sullen, but it was the self-doubting sullenness of the uneasy child. Perhaps, when he took the same shilling, he had not bargained on being the instrument that would prepare an innocent man for the hangman's noose. Not that Mac would compromise his own safety or risk his own skin to save him, but he squirmed far more readily than Crellin. The cross-legged inquisitor gave him not a moment's rest from the steady eyes. At first Mac pretended not to notice, but in the confined dimensions of the cell he could not help it. He got up and stood at the opaque window glass, for all the world as if he could see through it and admire the view. He turned his chair and sat sideways to the man he was guarding. He pretended to read. He clasped his hands behind his back and with head lowered paced an absurd eight-foot sentry-go across the cell and back, as if in deep thought. And then he turned to Holmes and shouted,
âLook somewhere else, will you? Look somewhere else, blast your eyes!'
But the man whom he must help to kill spoke not a word from Mac's entry at morning until his departure at evening. After his first two days it was plain that Mac dreaded the cell. Holmes had found a weakness in their scheme, not in chains or locks, or in hyoscine. It existed in the man they called Mac. The man's flaw was a tender conscience, and the poor devil dreaded that any of the others should detect it. Holmes could tell this by the way he loudly and unevenly, with his fellow jailers before entering the cell, laughed for Holmes to hear him and know that he cared nothing. Once inside, before the keen-eyed inquisitor, it was a different story.
Sherlock Holmes, for all his fame, was a mortal man. Neither I nor any other living soul was ever to know what terrors he may have felt in these long hours. Yet not by a word or the blink of an eyelid did he betray them. There are those who will scoff and tell you that all this was the bravado of a schoolbook hero. It was nothing of the kind but, rather, his inner concentration on the nub of a plan formed in a mind that was hard as a diamond and by thoughts clear as perfect crystal. He must judge to the minute when the silence was to be broken. There would be one chance and one chance only. The moment came on the fourth day, in the middle of a long afternoon. His words were spoken loudly but not too loudly. The tone, however, was sharp as the crack of a circus whip and Mac jumped at the sound of them.
âListen to me, McIver!'
Perhaps it was the sound of his own name, spoken by a man who could never have heard it used, that broke the fellow's composure. Cross-legged and still, Sherlock Holmes spoke again. His voice was too soft to be heard beyond the cell, and it now seemed intended to comfort the man who had been set to keep watch on him.
âI think, Corporal McIver of the 21st Lancers, that it is time for you and me to exchange a few words.'
The reddened skin grew tight as a mask on the cheekbone, and the elongated eyes looked straight at Holmes, stilled by fear, like a rat before a basilisk.
âI understand entirely,' Holmes continued. âThe first thought in your mind is that Mr. Milvertonâor by whatever name your master calls himselfâwill cut your throat once he knows that you have revealed your identity to me. You are, or rather were, Corporal McIver of the 21st Lancers, a veteran of the cavalry charge against the Sudanese rebels at the Battle of Omdurman, lately discharged from the Army as the victim of a distressing medical complaintâEgyptian ophthalmia. All you wish now is to marry your childhood sweetheart. But that is not easy, is it?'
Holmes had softened him up carefully over many hours. Now the mesmerised incomprehension in McIver's eyes turned to outright fear.
âYou cannot have set eyes upon me until you saw me in this place,' he said in a stage whisper, fearful of being heard by those outside the cell, âand I know nothing of you. You cannot tell me who I am.'
âQuite so,' said Holmes soothingly. âHowever, let me assure you I know enoughâif not allâabout you. The 21st Lancers, the Battle of Omdurman, your discharge from the Army on medical grounds. The woman you had hoped to marry. I know more than enough to have left a hidden message already, scratched somewhere and somehowâin the plaster of a wall perhaps. When this building is dismantled, as it soon will be, such a message including your name would lead the police straight to you. It has even been known for a prisoner in this very gaolâBenson was his nameâto leave a dampened paper message on the floor where one of the guards would tread on it unwittingly and just as unwittingly lose it on the dry pavement outside these walls. Have no fear. I am sure you have been warned against such tricks. There are far better ones than that, believe me.'
âMr. Milverton knows of all your tricks,' said McIver hastily.
âNot quite all of them, I think,' said Holmes amiably. âWhat Mr. Milverton does know, however, is that once in the hands of the police, you would betray him and his entire conspiracy. And you know perfectly well, Corporal McIver, that were I to say as much to him as I am saying to you now, you would be dead before this evening's sun had set.'
âWhat can you tell?'
âEnough to end your life even before mine. If your master knew that I had identified you and had already taken measures to pass on that knowledge, you would not live the hour. He would not dare allow it. Whether I inform him or not is a matter for you.'
The eyes that had fled from Holmes's scrutiny before could not bear now to leave his face. In a sudden flood of panic, the discharged soldier had fallen victim completely to Holmes's precept that âWhat you can do in this world is a matter of no consequence. The question is what can you make people believe that you have done.' He had not half finished with the wretch, while McIver struggled to imagine how a total stranger could have known so much about him.
âWhen you were invalided home from Egypt,' Holmes continued, âand discharged from your regiment, you were thrown upon your own resources. Had you held the rank of sergeant, a pension might have been procured for you. Yet a sergeant is, shall we say,
rara avis in terra
âa rare bird. If I am not mistaken, a cavalry troop consists of some sixty troopers plus six corporals and one sergeant. You were not he. It is not to be wondered at that you have failed to find regular employment since your return. Your malady sits plainly upon you.'
As Holmes was talking, McIver's face showed the contending emotions of a man who feels himself ever more securely snared and yet hopes that the snare may break and set him free.
âYou may guess, Mr. Sherlock Holmes,' he said, mingling scorn with trepidation, âbut you cannot know. Mr. Milverton would see your tale for what it is.'
âI do not guess,' said Holmes mildly. âI never guess. Mr. Milverton knows that, to his cost. You appear to forget that while you have watched me in the past few days, I have also watched you. You are a mere prison guard, but it is my profession to observe. Your name was easy to discover. Indeed, at my arrival I heard distinctly one of your accomplices call you Mac.'
McIver got up from his chair and stood as if he might advance upon his prisoner. âThat is nothing!'
âIn itself.â¦' There was something like steel in Holmes's voice that made the man sit down again. âIn itself it is nothing. However, I have had ample opportunity of observing you, even when you were out of earshot. I had a distinct view on the second day, as I was led back down the corridor. The man I believe you call Crellin stood behind you and spoke. You turned to him. He had spoken a nameâor a wordâto make you turn. I assumed it was your name and, of course, lipreading is necessary in my walk of life. Indeed, I have written a little monograph on the production of sound from labial distortion. From the chuckle to the scream.'
McIver was staring at him now, as if he dared not miss a word.
âWell, now,' Holmes went on, âI had no doubt that the first syllable of the word spoken by Crellin was âMac.' I would expect that anyway, for I had heard you called by it. Try forming it for yourself. There is a characteristic compression of the lips followed by a sideways opening of the mouth. Crellin's lips then made the shape of an âi.' This is easily read, being the letter which opens the mouth higher and narrower than any other. Quite unmistakable. Then his upper teeth touched his lower lip harder than they would to make an âf.' Therefore, the sound could only be a âv.' Finally, the lips protruded in a flute-like way and the skin on his throat was strained a little tighter. To the trained eye, this could only be âer.' It was not difficult.'
âVery clever!' The man was shaken but still scornful.
âAnd then there are your boots,' said Holmes.
âWhat of 'em?'
âArmy boots,' Holmes said, âstill worn by you after your discharge.'
âAny man could buy boots like these. Workmen's boots, more like than army ones.'
âIndeed,' said Holmes indulgently. âHowever, such boots are made of black pimpled leather and are worn as such by civilian workmen. Yet consider this. Any man who has been a soldier knows that the first command to the unfortunate recruit is to take a hot iron and to iron out the pimples of the toe caps so that they are perfectly smooth. They can then be polished for the parade ground until, if you will forgive the cliché, the poor recruit can see his face in them. Your boots are not those bought by a civilian worker. Rather, they are boots worn by a man who has lately been a soldier and can afford no others.'
For some reason, the revelation about his boots shook McIver more thoroughly than the discovery of his name.
âWhy are you not afraid?' he asked Holmes suddenly. âI do not understand it.'
Holmes smiled at him, the lips thin and hard.
âIf I were afraid, not you or any man should know it. For fear merely begets fear, and that would never do. Allow me to proceed. Boots of that kind are not worn by a sergeant, whose footwear gleams all over and is of an easier type. Therefore, you could only be a corporal or a private trooper. Oh, do not ask me how I knew you were a horseman. Merely watch the way you walk, when next you pass a plate-glass window. You have recently done some years of foreign service. Your complexion tells one at a glance. I deduce that you went with Lord Kitchener's expedition to reconquer the Sudan six years ago. A soldier who suffers, as you do, from Egyptian ophthalmia can scarcely dispute that. All the other mounted regiments of that force were Egyptian levees. Any man who reads his morning newspaper knows that the 21st Lancers were drafted in to lead the charge at Omdurman and that they were the only British mounted regiment sent for that purpose.'
It was with some gratification that Holmes saw the man bow his head and stare at the floor of the cell to hide his confusion.
âSolar discoloration of the epidermis is a phenomenon essential to the work of the criminal expert,' Holmes assured him quietly. âIn your case, the effects of the Egyptian sun have been prolonged and have hardly begun to fade. The inner surfaces of your wrists remain white, as does a thin margin along the hairline of your forehead, which was covered by your helmet. There is a marked degree of permanency in the burning elsewhere. I judge that this would not have been acquired in less than five or six years, which approximates to the departure of the 21st Lancers for service in the Sudan campaign. You are evidently a man of some capability, and such a man does not usually serve in a single posting for six years without rising to the rank of corporal or, at any rate, of acting corporal. There are significant losses among a regiment overseas for six years, more from sickness than from battle, and significant vacancies for promotion. In either rank you would be referred to as Corporal McIver. Your modest advancement suggests to me a satisfactory character as a soldier and that you have lately turned to crime from particular necessity and not from mere viciousness.'
