as he never leaves his room now, he could not get any from outside."
"What about the servants?" I asked.
"There are no servants excepting my housekeeper, and she is absolutely trustworthy."
"He might have some store of the drug that you are not aware of. Is he left alone much?"
"Very seldom indeed. I spend as much time with him as I can, and when I am not able to be in the room, Mrs. Schallibaum, my housekeeper, sits with him."
"Is he often as drowsy as he is now?"
"Oh, very often; in fact, I should say that is his usual condition. He rouses up now and again, and then he is quite lucid and natural for, perhaps, an hour or so; but presently he becomes drowsy again and doses off, and remains asleep, or half asleep, for hours on end. Do you know of any disease that takes people in that way?"
"No," I answered. "The symptoms are not exactly like those of any disease that is known to me. But they are much very like those of opium poisoning."
"But, my dear sir," Mr. Weiss retorted impatiently, "since it is clearly impossible that it can be opium poisoning, it must be something else. Now, what else can it be? You were speaking of congestion of the brain."
"Yes. But the objection to that is the very complete recovery that seems to take place in the intervals."
"I would not say very complete," said Mr. Weiss. "The recovery is rather comparative. He is lucid and fairly natural in his manner, but he is still dull and lethargic. He does not, for instance, show any desire to go out, or even to leave his room."
I pondered uncomfortably on these rather contradictory statements. Clearly Mr. Weiss did not mean to entertain the theory of opium poisoning; which was natural enough if he had no knowledge of the drug having been used. But still—
"I suppose," said Mr. Weiss, "you have experience of sleeping sickness?"
The suggestion startled me. I had not. Very few people had. At that time practically nothing was known about the disease. It was a mere pathological curiosity, almost unheard of excepting by a few practitioners in remote parts of Africa, and hardly referred to in the text-books. Its connection with the trypanosome-bearing insects was as yet unsuspected, and, to me, its symptoms were absolutely unknown.
"No, I have not," I replied. "The disease is nothing more than a name to me. But why do you ask? Has Mr. Graves been abroad?"
"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
