seen me, and I had to run to my burrow when I heard the window go up.'
'But what in heaven's name is the matter?'
'Well, it's not a long story to tell,' said he, lighting a cigarette. 'You remember that morning fight at Buffelsspruit, outside Pretoria, on the Eastern railway line? You heard I was hit?'
'Yes, I heard that but I never got particulars.'
'Three of us got separated from the others. It was very broken country, you may remember. There was Simpson — the fellow we called Baldy Simpson — and Anderson, and I. We were clearing brother Boer, but he lay low and got the three of us. The other two were killed. I got an elephant bullet through my shoulder. I stuck on to my horse, however, and he galloped several miles before I fainted and rolled off the saddle.
'When I came to myself it was nightfall, and I raised myself up, feeling very weak and ill. To my surprise there was a house close beside me, a fairly large house with a broad stoep and many windows. It was deadly cold. You remember the kind of numb cold which used to come at evening, a deadly, sickening sort of cold, very different from a crisp healthy frost. Well, I was chilled to the bone, and my only hope seemed to lie in reaching that house. I staggered to my feet and dragged myself along, hardly conscious of what I did. I have a dim memory of slowly ascending the steps, entering a wide-opened door, passing into a large room which contained several beds, and throwing myself down with a gasp of satisfaction upon one of them. It was unmade, but that troubled me not at all. I drew the clothes over my shivering body and in a moment I was in a deep sleep.
'It was morning when I wakened, and it seemed to me that instead of coming out into a world of sanity I had emerged into some extraordinary nightmare. The African sun flooded through the big, curtainless windows, and every detail of the great, bare, whitewashed dormitory stood out hard and clear. In front of me was standing a small, dwarf-like man with a huge, bulbous head, who was jabbering excitedly in Dutch, waving two horrible hands which looked to me like brown sponges. Behind him stood a group of people who seemed to be intensely amused by the situation, but a chill came over me as I looked at them. Not one of them was a normal human being. Every one was twisted or swollen or disfigured in some strange way. The laughter of these strange monstrosities was a dreadful thing to hear.
'It seemed that none of them could speak English, but the situation wanted clearing up, for the creature with the big head was growing furiously angry, and, uttering wild-beast cries, he had laid his deformed hands upon me and was dragging me out of bed, regardless of the fresh flow of blood from my wound. The little monster was as strong as a bull, and I don't know what he might have done to me had not an elderly man who was clearly in authority been attracted to the room by the hubbub; He said a few stern words in Dutch, and my persecutor shrank away. Then he turned upon me, gazing at me in the utmost amazement.
''How in the world did you come here?' he asked in amazement. 'Wait a bit! I see that you are tired out and that wounded shoulder of yours wants looking after. I am a doctor, and I'll soon have you tied up. But, man alive! you are in far greater danger here than ever you were on the battlefield. You are in the Leper Hospital, and you have slept in a leper's bed.'
'Need I tell you more, Jimmie? It seems that in view of the approaching battle all these poor creatures had been evacuated the day before. Then, as the British advanced, they had been brought back by this, their medical superintendent, who assured me that, though he believed he was immune to the disease, he would none the less never have dared to do what I had done. He put me in a private room, treated me kindly, and within a week or so I was removed to the general hospital at Pretoria.
'So there you have my tragedy. I hoped against hope, but it was not until I had reached home that the terrible signs which you see upon my face told me that I had not escaped. What was I to do? I was in this lonely house. We had two servants whom we could utterly trust. There was a house where I could live. Under pledge of secrecy, Mr. Kent, who is a surgeon, was prepared to stay with me. It seemed simple enough on those lines. The alternative was a dreadful one — segregation for life among strangers with never a hope of release. But absolute secrecy was necessary, or even in this quiet countryside there would have been an outcry, and I should have been dragged to my horrible doom. Even you, Jimmie — even you had to be kept in the dark. Why my father has relented I cannot imagine.'
Colonel Emsworth pointed to me.
'This is the gentleman who forced my hand.' He unfolded the scrap of paper on which I had written the word 'Leprosy.' 'It seemed to me that if he knew so much as that it was safer that he should know all.'
'And so it was,' said I. 'Who knows but good may come of it? I understand that only Mr. Kent has seen the patient. May I ask, sir, if you are an authority on such complaints, which are, I understand, tropical or semi-tropical in their nature?'
'I have the ordinary knowledge of the educated medical man,' he observed with some stiffness.
'I have no doubt, sir, that you are fully competent, but I am sure that you will agree that in such a case a second opinion is valuable. You have avoided this, I understand, for fear that pressure should be put upon you to segregate the patient.'
'That is so,' said Colonel Emsworth.
'I foresaw this situation,' I explained, 'and I have brought with me a friend whose discretion may absolutely be trusted. I was able once to do him a professional service, and he is ready to advise as a friend rather than as a specialist. His name is Sir James Saunders.'
The prospect of an interview with Lord Roberts would not have excited greater wonder and pleasure in a raw subaltern than was now reflected upon the face of Mr. Kent.
'I shall indeed be proud,' he murmured.
'Then I will ask Sir James to step this way. He is at present in the carriage outside the door. Meanwhile, Colonel Emsworth, we may perhaps assemble in your study, where I could give the necessary explanations.'
And here it is that I miss my Watson. By cunning questions and ejaculations of wonder he could elevate my simple art, which is but systematized common sense, into a prodigy. When I tell my own story I have no such aid. And yet I will give my process of thought even as I gave it to my small audience, which included Godfrey's mother in the study of Colonel Emsworth.
'That process,' said I, 'starts upon the supposition that when you have eliminated all which is impossible, then whatever remains, however improbable, must be the truth. It may well be that several explanations remain, in which case one tries test after test until one or other of them has a convincing amount of support. We will now apply this principle to the case in point. As it was first presented to me, there were three possible explanations of the seclusion or incarceration of this gentleman in an outhouse of his father's mansion. There was the explanation that he was in hiding for a crime, or that he was mad and that they wished to avoid an asylum, or that he had some disease which caused his segregation. I could think of no other adequate solutions. These, then, had to be sifted and balanced against each other.
'The criminal solution would not bear inspection. No unsolved crime had been reported from that district. I was sure of that. If it were some crime not yet discovered, then clearly it would be to the interest of the family to get rid of the delinquent and send him abroad rather than keep him concealed at home. I could see no explanation for such a line of conduct.
'Insanity was more plausible. The presence of the second person in the outhouse suggested a keeper. The fact that he locked the door when he came out strengthened the supposition and gave the idea of constraint. On the other hand, this constraint could not be severe or the young man could not have got loose and come down to have a look at his friend. You will remember, Mr. Dodd, that I felt round for points, asking you, for example, about the paper which Mr. Kent was reading. Had it been the Lancet or the British Medical Journal it would have helped me. It is not illegal, however, to keep a lunatic upon private premises so long as there is a qualified person in attendance and that the authorities have been duly notified. Why, then, all this desperate desire for secrecy? Once again I could not get the theory to fit the facts.
'There remained the third possibility, into which, rare and unlikely as it was, everything seemed to fit. Leprosy is not uncommon in South Africa. By some extraordinary chance this youth might have contracted it. His people would be placed in a very dreadful position, since they would desire to save him from segregation. Great secrecy would be needed to prevent rumours from getting about and subsequent interference by the authorities. A devoted medical man, if sufficiently paid, would easily be found to take charge of the sufferer. There would be no reason why the latter should not be allowed freedom after dark. Bleaching of the skin is a common result of the disease. The case was a strong one — so strong that I determined to act as if it were actually proved. When on arriving here I noticed that Ralph, who carries out the meals, had gloves which are impregnated with disinfectants,
