"Yes. He has been travelling for the last three or four years, and I know that he spent some time recently in West Africa, where this disease occurs. In fact, it was from him that I first heard about it."

This was a new fact. It shook my confidence in my diagnosis very considerably, and inclined me to reconsider my suspicions. If Mr. Weiss was lying to me, he now had me at a decided disadvantage.

"What do you think?" he asked. "Is it possible that this can be sleeping sickness?"

"I should not like to say that it is impossible," I replied. "The disease is practically unknown to me. I have never practised out of England and have had no occasion to study it. Until I have looked the subject up, I should not be in a position to give an opinion. Of course, if I could see Mr. Graves in one of what we may call his 'lucid intervals' I should be able to form a better idea. Do you think that could be managed?"

"It might. I see the importance of it and will certainly do my best; but he is a difficult man; a very difficult man. I sincerely hope it is not sleeping sickness."

"Why?"

"Because—as I understood from him—that disease is invariably fatal, sooner or later. There seem to be no cure. Do you think you will be able to decide when you see him again?"

"I hope so," I replied. "I shall look up the authorities and see exactly what the symptoms are—that is, so far as they are known; but my impression is that there is very little information available."

"And in the meantime?"

"We will give him some medicine and attend to his general condition, and you had better let me see him again as soon as possible." I was about to say that the effect of the medicine itself might throw some light on the patient's condition, but, as I proposed to treat him for morphine poisoning, I thought it wiser to keep this item of information to myself. Accordingly, I confined myself to a few general directions as to the care of the patient, to which Mr. Weiss listened attentively. "And," I concluded, "we must not lose sight of the opium question. You had better search the room carefully and keep a close watch on the patient, especially during his intervals of wakefulness."

"Very well, doctor," Mr. Weiss replied, "I will do all that you tell me and I will send for you again as soon as possible, if you do not object to poor Graves's ridiculous conditions. And now, if you will allow me to pay your fee, I will go and order the carriage while you are writing the prescription."

"There is no need for a prescription," I said. "I will make up some medicine and give it to the coachman."

Mr. Weiss seemed inclined to demur to this arrangement, but I had my own reasons for insisting on it. Modern prescriptions are not difficult to read, and I did not wish Mr. Weiss to know what treatment the patient was having.

As soon as I was left alone, I returned to the bedside and once more looked down at the impassive figure. And as I looked, my suspicions revived. It was very like morphine poisoning; and, if it was morphine, it was no common, medicinal dose that had been given. I opened my bag and took out my hypodermic case from which I extracted a little tube of atropine tabloids. Shaking out into my hand a couple of the tiny discs, I drew down the patient's under-lip and slipped the little tablets under his tongue. Then I quickly replaced the tube and dropped the case into my bag; and I had hardly done so when the door opened softly and the housekeeper entered the room.

"How do you find Mr. Graves?" she asked in what I thought a very unnecessarily low tone, considering the patient's lethargic state.

"He seems to be very ill," I answered.

"So!" she rejoined, and added: "I am sorry to hear that. We have been anxious about him."

She seated herself on the chair by the bedside, and, shading the candle from the patient's face—and her own, too—produced from a bag that hung from her waist a half-finished stocking and began to knit silently and with the skill characteristic of the German housewife. I looked at her attentively (though she was so much in the shadow that I could see her but indistinctly) and somehow her appearance prepossessed me as little as did that of the other members of the household. Yet she was not an ill-looking woman. She had an excellent figure, and the air of a person of good social position; her features were good enough and her colouring, although a little unusual, was not unpleasant. Like Mr. Weiss, she had very fair hair, greased, parted in the middle and brushed down as smoothly as the painted hair of a Dutch doll. She appeared to have no eyebrows at all—owing, no doubt, to the light colour of the hair—and the doll-like character was emphasized by her eyes, which were either brown or dark grey, I could not see which. A further peculiarity consisted in a "habit spasm," such as one often sees in nervous children; a periodical quick jerk of the head, as if a cap-string or dangling lock were being shaken off the cheek. Her age I judged to be about thirty-five.

The carriage, which one might have expected to be waiting, seemed to take some time in getting ready. I sat, with growing impatience, listening to the sick man's soft breathing and the click of the housekeeper's knitting-needles. I wanted to get home, not only for my own sake; the patient's condition made it highly desirable that the remedies should be given as quickly as possible. But the minutes dragged on, and I was on the point of expostulating when a bell rang on the landing.

"The carriage is ready," said Mrs. Schallibaum. "Let me light you down the stairs."

She rose, and, taking the candle, preceded me to the head of the stairs, where she stood holding the light over the baluster-rail as I descended and crossed the passage to the open side door. The carriage was drawn up in the covered way as I could see by the faint glimmer of the distant candle; which also enabled me dimly to discern the coachman standing close by in the shadow. I looked round, rather expecting to see Mr. Weiss, but, as he made no appearance, I entered the carriage. The door was immediately banged to and locked, and I then heard the heavy bolts of the gates withdrawn and the loud creaking of hinges. The carriage moved out slowly and stopped; the gates slammed to behind me; I felt the lurch as the coachman climbed to his seat and we started forward.

My reflections during the return journey were the reverse of agreeable. I could not rid myself of the conviction that I was being involved in some very suspicious proceedings. It was possible, of course, that this feeling was due to the strange secrecy that surrounded my connection with this case; that, had I made my visit under ordinary conditions, I might have found in the patient's symptoms nothing to excite suspicion or alarm. It might be so, but that consideration did not comfort me.

Then, my diagnosis might be wrong. It might be that this was, in reality, a case of some brain affection accompanied by compression, such as slow haemorrhage, abscess, tumour or simple congestion. These cases were very difficult at times. But the appearances in this one did not consistently agree with the symptoms accompanying any of these conditions. As to sleeping sickness, it was, perhaps a more hopeful suggestion, but I could not decide for or against it until I had more knowledge; and against this view was the weighty fact that the symptoms did exactly agree with the theory of morphine poisoning.

But even so, there was no conclusive evidence of any criminal act. The patient might be a confirmed opium-eater, and the symptoms heightened by deliberate deception. The cunning of these unfortunates is proverbial and is only equalled by their secretiveness and mendacity. It would be quite possible for this man to feign profound stupor so long as he was watched, and then, when left alone for a few minutes, to nip out of bed and help himself from some secret store of the drug. This would be quite in character with his objection to seeing a doctor and his desire for secrecy. But still, I did not believe it to be the true explanation. In spite of all the various alternative possibilities, my suspicions came back to Mr. Weiss and the strange, taciturn woman, and refused to budge.

For all the circumstances of the case were suspicious. The elaborate preparations implied by the state of the carriage in which I was travelling; the make-shift appearance of the house; the absence of ordinary domestic servants, although a coachman was kept; the evident desire of Mr. Weiss and the woman to avoid thorough inspection of their persons; and, above all, the fact that the former had told me a deliberate lie. For he had lied, beyond all doubt. His statement as to the almost continuous stupor was absolutely irreconcilable with his other statement as to the patient's wilfulness and obstinacy and even more irreconcilable with the deep and comparatively fresh marks of the spectacles on the patient's nose. That man had certainly worn spectacles within twenty-four hours, which he would hardly have done if he had been in a state bordering on coma.

My reflections were interrupted by the stopping of the carriage. The door was unlocked and thrown open, and I emerged from my dark and stuffy prison opposite my own house.

"I will let you have the medicine in a minute or two," I said to the coachman; and, as I let myself in with my latch-key, my mind came back swiftly from the general circumstances of the case to the very critical condition of the patient. Already I was regretting that I had not taken more energetic measures to rouse him and restore his flagging vitality; for it would be a terrible thing if he should take a turn for the worse and die before the coachman returned with the remedies. Spurred on by this alarming thought, I made up the medicines quickly and carried the hastily wrapped bottles out to the man, whom I found standing by the horse's head.

"Get back as quickly as you can," I said, "and tell Mr. Weiss to lose no time in giving the patient the draught in the small bottle. The directions are on the labels."

The coachman took the packages from me without reply, climbed to his seat, touched the horse with his whip and drove off at a rapid pace towards Newington Butts.

The little clock in the consulting-room showed that it was close on eleven; time for a tired G.P. to be thinking of bed. But I was not sleepy. Over my frugal supper I found myself taking up anew the thread of my meditations, and afterwards, as I smoked my last pipe by the expiring surgery fire, the strange and sinister features of the case continued to obtrude themselves on my notice. I looked up Stillbury's little reference library for information on the subject of sleeping sickness, but learned no more than that it was "a rare and obscure disease of which very little was known at present." I read up morphine poisoning and was only further confirmed in the belief that my diagnosis was correct; which would have been more satisfactory if the circumstances had been different.

For the interest of the case was not merely academic. I was in a position of great difficulty and responsibility and had to decide on a course of action. What ought I to do? Should I maintain the professional secrecy to which I was tacitly committed, or ought I to convey a hint to the police?

Suddenly, and with a singular feeling of relief, I bethought myself of my old friend and fellow-student, John Thorndyke, now an eminent authority on Medical Jurisprudence. I had been associated with him temporarily in one case as his assistant, and had then been deeply impressed by his versatile learning, his acuteness and his marvellous resourcefulness. Thorndyke was a barrister in extensive practice, and so would be able to tell me at once what was my duty from a legal point of view; and, as he was also a doctor of medicine, he would understand the exigencies of medical practice. If I could find time to call at the Temple and lay the case before him, all my doubts and difficulties would be resolved.

Anxiously, I opened my visiting-list to see what kind of day's work was in store for me on the morrow. It was not a heavy day, even allowing for one or two extra calls in the morning, but yet I was doubtful whether it would allow of my going so far from my district, until my eye caught, near the foot of the page, the name of Burton. Now Mr. Burton lived in one of the old houses on the east side of Bouverie Street, less than five minutes' walk from Thorndyke's chambers in King's Bench Walk; and he was, moreover, a "chronic" who could safely be left for the last. When I had done with Mr. Burton I could look in on my friend with a very good chance of catching him on his return from the hospital. I could allow myself time for quite a long chat with him, and, by taking a hansom, still get back in good time for the evening's work.

This was a great comfort. At the prospect of sharing my responsibilities with a friend on whose judgment I could so entirely rely, my embarrassments seemed to drop from me in a moment. Having entered the engagement in my visiting-list, I rose, in greatly improved spirits, and knocked out my pipe just as the little clock banged out impatiently the hour of midnight.

Chapter II

Thorndyke Devises a Scheme

As I entered the Temple by the Tudor Street gate the aspect of the place smote my senses with an air of agreeable familiarity. Here had I spent many a delightful hour when working with Thorndyke at the remarkable Hornby case, which the newspapers had called "The Case of the Red Thumb Mark"; and here had I met the romance of my life, the story whereof is told elsewhere. The place was thus endeared to me by pleasant recollections of a happy past, and its associations suggested hopes of happiness yet to come and in the not too far distant future.

My brisk tattoo on the little brass knocker brought to the door no less a person than Thorndyke himself; and the warmth of his greeting made me at once proud and ashamed. For I had not only been an absentee; I had been a very poor correspondent.

"The prodigal has returned, Polton," he exclaimed, looking into the room. "Here is Dr. Jervis."

I followed him into the room and found Polton—his confidential servant, laboratory assistant, artificer and general "familiar"—setting out the tea-tray on a small table. The little man shook hands cordially with me, and his face crinkled up into the sort of smile that one might expect to see on a benevolent walnut.

"We've often talked about you, sir," said he. "The doctor was wondering only yesterday when you were coming back to us."

As I was not "coming back to them" quite in the sense intended I felt a little guilty, but reserved my confidences for Thorndyke's ear and replied in polite generalities. Then Polton fetched the tea-pot from the laboratory, made up the fire and departed, and Thorndyke and I subsided, as of old, into our respective arm-chairs.

"And whence do you spring from in this unexpected fashion?" my colleague asked. "You look as if you had been making professional visits."

"I have. The base of operations is in Lower Kennington Lane."

"Ah! Then you are 'back once more on the old trail'?"

"Yes," I answered, with a laugh, "'the old trail, the long trail, the trail that is always new.'"

"And leads nowhere," Thorndyke added grimly.

I laughed again; not very heartily, for there was an uncomfortable element of truth in my friend's remark, to which my own experience bore only too complete testimony. The medical practitioner whose lack of means forces him to subsist by taking temporary charge of other men's practices is apt to find that the passing years bring him little but grey hairs and a wealth of disagreeable experience.

"You will have to drop it, Jervis; you will, indeed," Thorndyke resumed after a pause. "This casual employment is preposterous for a man of your class and professional attainments. Besides, are you not engaged to be married and to a most charming girl?"

"Yes, I know. I have been a fool. But I will really amend my ways. If necessary, I will pocket my pride and let Juliet advance the money to buy a practice."

"That," said Thorndyke, "is a very proper resolution. Pride and reserve between people who are going to be husband and wife, is an absurdity. But why buy a practice? Have you forgotten my proposal?"

"I should be an ungrateful brute if I had."

"Very well. I repeat it now. Come to me as my junior, read for the Bar and work with me, and, with your abilities, you will have a chance of something like a career. I want you, Jervis," he added, earnestly. "I must have a junior, with my increasing practice, and you are the junior I want. We are old and tried friends; we have worked together; we like and trust one another, and you are the best man for the job that I know. Come; I am not going to take a refusal. This is an ultimatum."

"And what is the alternative?" I asked with a smile at his eagerness.

"There isn't any. You are going to say yes."

"I believe I am," I answered, not without emotion; "and I am more rejoiced at your offer and more grateful than I can tell you. But we must leave the final arrangements for our next meeting—in a week or so, I hope—for I have to be back in an hour, and I want to consult you on a matter of some importance."

"Very well," said Thorndyke; "we will leave the formal agreement for consideration at our next meeting. What is it that you want my opinion on?"

"The fact is," I said, "I am in a rather awkward dilemma, and I want you to tell me what you think I ought to do."

Thorndyke paused in the act of refilling my cup and glanced at me with unmistakable anxiety.

"Nothing of an unpleasant nature, I hope," said he.

"No, no; nothing of that kind," I answered with a smile as I interpreted the euphemism; for "something unpleasant," in the case of a young and reasonably presentable medical man is ordinarily the equivalent of trouble with the female of his species. "It is nothing that concerns me personally at all," I continued; "it is a question of professional responsibility. But I had better give you an account of the affair in a complete narrative, as I know that you like to have your data in a regular and consecutive order."

Thereupon I proceeded to relate the history of my visit to the mysterious Mr. Graves, not omitting any single circumstance or detail that I could recollect.

Thorndyke listened from the very beginning of my story with the closest attention. His face was the most impassive that I have ever seen; ordinarily as inscrutable as a bronze mask; but to me, who knew him intimately, there was a certain something—a change of colour, perhaps, or an additional sparkle of the eye—that told me when his curious passion for investigation was fully aroused. And now, as I told him of that weird journey and the strange, secret house to which it had brought me, I could see that it offered a problem after his very heart. During the whole of my narration he sat as motionless as a statue, evidently committing the whole story to memory, detail by detail; and even when I had finished he remained for an appreciable time without moving or speaking.

At length he looked up at me. "This is a very extraordinary affair, Jervis," he said.

"Very," I agreed; "and the question that is agitating me is, what is to be done?"

"Yes," he said, meditatively, "that is the question; and an uncommonly difficult question it is. It really involves the settlement of the antecedent question: What is it that is happening at that house?"

"What do you think is happening at that house?" I asked.

"We must go slow, Jervis," he replied. "We must carefully separate the legal tissues from the medical, and avoid confusing what we know with what we suspect. Now, with reference to the medical aspects of the case. The first question that confronts us is that of sleeping sickness, or negro-lethargy as it is sometimes called; and here we are in a difficulty. We have not enough knowledge. Neither of us, I take it, has ever seen a case, and the extant descriptions are inadequate. From what I know of the disease, its symptoms agree with those in your case in respect of the alleged moroseness and in the gradually increasing periods of lethargy alternating with periods of apparent recovery. On the other hand, the disease is said to be confined to negroes; but that probably means only that negroes alone have hitherto been exposed to the conditions that produce it. A more important fact is that, as far as I know, extreme contraction of the pupils is not a symptom of sleeping sickness. To sum up, the probabilities are against sleeping sickness, but with our insufficient knowledge, we cannot definitely exclude it."

"You think that it may really be sleeping sickness?"

"No; personally I do not entertain that theory for a moment. But I am considering the evidence apart from our opinions on the subject. We have to accept it as a conceivable hypothesis that it may be sleeping sickness because we cannot positively prove that it is not. That is all. But when we come to the hypothesis of morphine poisoning, the case is different. The symptoms agree with those of morphine poisoning in every respect. There is no exception or disagreement whatever. The common sense of the matter is therefore that we adopt morphine poisoning as our working diagnosis; which is what you seem to have done."

"Yes. For purposes of treatment."

"Exactly. For medical purposes you adopted the more probable view and dismissed the less probable. That was the reasonable thing to do. But for legal purposes you must entertain both possibilities; for the hypothesis of poisoning involves serious legal issues, whereas the hypothesis of disease involves no legal issues at all."

"That doesn't sound very helpful," I remarked.

"It indicates the necessity for caution," he retorted.

"Yes, I see that. But what is your own opinion of the case?"

"Well," he said, "let us consider the facts in order. Here is a man who, we assume, is under the influence of a poisonous dose of morphine. The question is, did he take that dose himself or was it administered to him by some other person? If he took it himself, with what object did he take it? The history that was given to you seems completely to exclude the idea of suicide. But the patient's condition seems equally to exclude the idea of morphinomania. Your opium-eater does not reduce himself to a state of coma. He usually keeps well within the limits of the tolerance that has been established. The conclusion that emerges is, I think, that the drug was administered by some other person; and the most likely person seems to be Mr. Weiss."

"Isn't morphine a very unusual poison?"

"Very; and most inconvenient except in a single, fatal dose, by reason of the rapidity with which tolerance of the drug is established. But we must not forget that slow morphine poisoning might be eminently suitable in certain cases. The manner in which it enfeebles the will, confuses the judgment and debilitates the body might make it very useful to a poisoner whose aim was to get some instrument or document executed, such as a will, deed or assignment. And death could be produced afterwards by other means. You see the important bearing of this?"

"You mean in respect of a death certificate?"

"Yes. Suppose Mr. Weiss to have given a large dose of morphine. He then sends for you and throws out a suggestion of sleeping sickness. If you accept the suggestion he is pretty safe. He can repeat the process until he kills his victim and then get a certificate from you which will cover the murder. It was quite an ingenious scheme—which, by the way, is characteristic of intricate crimes; your subtle criminal often plans his crime like a genius, but he generally executes it like a fool—as this man seems to have done, if we are not doing him an injustice."

"How has he acted like a fool?"

"In several respects. In the first place, he should have chosen his doctor. A good, brisk, confident man who 'knows his own mind' is the sort of person who would have suited him; a man who would have jumped at a diagnosis and stuck to it; or else an ignorant weakling of alcoholic tendencies. It was shockingly bad luck to run against a cautious scientific practitioner like my learned friend. Then, of course, all this secrecy was sheer tomfoolery, exactly calculated to put a careful man on his guard; as it has actually done. If Mr. Weiss is really a criminal, he has mismanaged his affairs badly."

"And you apparently think that he is a criminal?"

"I suspect him deeply. But I should like to ask you one or two questions about him. You say he spoke with a German accent. What command of English had he? Was his vocabulary good? Did he use any German idioms?"

"No. I should say that his English was perfect, and I noticed that his phrases were quite well chosen even for an Englishman."

"Did he seem to you 'made up' in any way; disguised, I mean?"

"I couldn't say. The light was so very feeble."

"You couldn't see the colour of his eyes, for instance?"

"No. I think they were grey, but I couldn't be sure."

"And as to the coachman. He wore a wig, you said. Could you see the colour of his eyes? Or any peculiarity by which you could recognize him?"

"He had a malformed thumb-nail on his right hand. That is all I can say about him."

"He didn't strike you as resembling Weiss in any way; in voice or features?"

"Not at all; and he spoke, as I told you, with a distinct Scotch accent."

"The reason I ask is that if Weiss is attempting to poison this man, the coachman is almost certain to be a confederate and might be a relative. You had better examine him closely if you get another chance."

"I will. And that brings me back to the question, What am I to do? Ought I to report the case to the police?"

"I am inclined to think not. You have hardly enough facts. Of course, if Mr. Weiss has administered poison 'unlawfully and maliciously' he has committed a felony, and is liable under the Consolidation Acts of 1861 to ten years' penal servitude. But I do not see how you could swear an information. You don't know that he administered the poison—if poison has really been administered—and you cannot give any reliable name or any address whatever. Then there is the question of sleeping sickness. You reject it for medical purposes, but you could not swear, in a court of law, that this is not a case of sleeping sickness."

"No," I admitted, "I could not."

"Then I think the police would decline to move in the matter, and you might find that you had raised a scandal in Dr. Stillbury's practice to no purpose."

"So you think I had better do nothing in the matter?"

"For the present. It is, of course, a medical man's duty to assist justice in any way that is possible. But a doctor is not a detective; he should not go out of his way to assume police functions. He should keep his eyes and ears open, and, though, in general, he should keep his own counsel, it is his duty to note very carefully anything that seems to him likely to bear on any important legal issues. It is not his business officiously to initiate criminal inquiries, but it is emphatically his business to be ready, if called upon, to assist justice with information that his special knowledge and opportunities have rendered accessible to him. You see the bearing of this?"

"You mean that I should note down what I have seen and heard and say nothing about it until I am asked."

"Yes; if nothing further happens. But if you should be sent for again, I think it is your duty to make further observations with a view, if necessary, to informing the police. It may be, for instance, of vital importance to identify the house, and it is your duty to secure the means of doing so."

"But, my dear Thorndyke," I expostulated, "I have told you how I was conveyed to the house. Now, will you kindly explain to me how a man, boxed up in a pitch-dark carriage, is going to identify any place to which he may be carried?"

"The problem doesn't appear to me to present any serious difficulties," he replied.

"Doesn't it?" said I. "To me it looks like a pretty solid impossibility. But what do you suggest? Should I break out of the house and run away up the street? Or should I bore a hole through the shutter of the carriage and peep out?"

Thorndyke smiled indulgently. "The methods proposed by my learned friend display a certain crudity inappropriate to the character of a man of science; to say nothing of the disadvantage of letting the enemy into our counsels. No, no, Jervis; we can do something better than that. Just excuse me for a minute while I run up to the laboratory."

He hurried away to Polton's sanctum on the upper floor, leaving me to speculate on the method by which he proposed that a man should be enabled, as Sam Weller would express it, "to see through a flight of stairs and a deal door"; or, what was equally opaque, the wooden shutters of a closed carriage.

"Now," he said, when he returned a couple of minutes later with a small, paper-covered notebook in his hand, "I have set Polton to work on a little appliance that will, I think, solve our difficulty, and I will show you how I propose that you should make your observations. First of all, we have to rule the pages of this book into columns."

He sat down at the table and began methodically to rule the pages each into three columns, two quite narrow and one broad. The process occupied some time, during which I sat and watched with impatient curiosity the unhurried, precise movements of Thorndyke's pencil, all agog to hear the promised explanation. He was just finishing the last page when there came a gentle tap at the door, and Polton entered with a satisfied smile on his dry, shrewd-looking face and a small board in his hand.

"Will this do, sir?" he asked.

As he spoke he handed the little board to Thorndyke, who looked at it and passed it to me.

"The very thing, Polton," my friend replied. "Where did you find it? It's of no use for you to pretend that you've made it in about two minutes and a half."
