Mortimer Tregennis explained that the night was cold and damp. For that reason, after his arrival, the fire was lit. "What are you going to do now, Mr. Holmes?" he asked.
My friend smiled and laid his hand upon my arm. "I think, Watson, that I shall resume that course of tobacco-poisoning which you have so often and so justly condemned," said he. "With your permission, gentlemen, we will now return to our cottage, for I am not aware that any new factor is likely to come to our notice here. I will turn the facts over in my mind, Mr. Tregennis, and should anything occur to me I will certainly communicate with you and the vicar. In the meantime I wish you both good-morning."
It was not until long after we were back in Poldhu Cottage that Holmes broke his complete and absorbed silence. He sat coiled in his armchair, his haggard and ascetic face hardly visible amid the blue swirl of his tobacco smoke, his black brows drawn down, his forehead contracted, his eyes vacant and far away. Finally he laid down his pipe and sprang to his feet. "It won't do, Watson!" said he with a laugh. "Let us walk along the cliffs together and search for flint arrows. We are more likely to find them than clues to this problem. To let the brain work without sufficient material is like racing an engine. It racks itself to pieces. The sea air, sunshine, and patience, Watson – all else will come.
"Now, let us calmly define our position, Watson," he continued as we skirted the cliffs together. "Let us get a firm grip of the very little which we do know, so that when fresh facts arise we may be ready to fit them into their places. I take it, in the first place, that neither of us is prepared to admit diabolical intrusions into the affairs of men. Let us begin by ruling that entirely out of our minds. Very good. There remain three persons who have been grievously stricken by some conscious or unconscious human agency. That is firm ground. Now, when did this occur? Evidently, assuming his narrative to be true, it was immediately after Mr. Mortimer Tregennis had left the room. That is a very important point. The presumption is that it was within a few minutes afterwards. The cards still lay upon the table. It was already past their usual hour for bed. Yet they had not changed their position or pushed back their chairs. I repeat then, that the occurrence was immediately after his departure, and not later than eleven o'clock last night.
"Our next obvious step is to check, so far as we can, the movements of Mortimer Tregennis after he left the room. In this there is no difficulty, and they seem to be above suspicion. Knowing my methods as you do, you were, of course, conscious of the somewhat clumsy water-pot expedient by which I obtained a clearer impress of his foot than might otherwise have been possible. The wet, sandy path took it admirably. Last night was also wet, you will remember, and it was not difficult – having obtained a sample print – to pick out his track among others and to follow his movements. He appears to have walked away swiftly in the direction of the vicarage.
"If, then, Mortimer Tregennis disappeared from the scene, and yet some outside person affected the card players, how can we reconstruct that person, and how was such an impression of horror conveyed? Mrs. Porter may be eliminated. She is evidently harmless. Is there any evidence that someone crept up to the garden window and in some manner produced so terrific an effect that he drove those who saw it out of their senses? The only suggestion in this direction comes from Mortimer Tregennis himself, who says that his brother spoke about some movement in the garden. That is certainly remarkable, as the night was rainy, cloudy, and dark. Anyone who had the design to alarm these people would be compelled to place his very face against the glass before he could be seen. There is a three-foot flower border outside this window, but no indication of a footmark. It is difficult to imagine, then, how an outsider could have made so terrible an impression upon the company, nor have we found any possible motive for so strange and elaborate an attempt. You perceive our difficulties, Watson?"
"They are only too clear," I answered with conviction.
"And yet, with a little more material, we may prove that they are not insurmountable," said Holrnes. "I fancy that among your extensive archives, Watson, you may find some which were nearly as obscure. Meanwhile, we shall put the case aside until more accurate data are available, and devote the rest of our morning to the pursuit of Neolithic man."
I may have commented upon my friend's power of mental detachment, but never have I wondered at it more than upon that spring morning in Cornwall when for two hours he discoursed upon Celts, arrowheads, and shards, as lightly as if no sinister mystery were waiting for his solution. It was not until we had returned in the afternoon to our cottage that we found a visitor awaiting us, who soon brought our minds back to the matter in hand. Neither of us needed to be told who that visitor was. The huge body, the craggy and deeply seamed face with the fierce eyes and hawk-like nose, the grizzled hair which nearly brushed our cottage ceiling, the beard – golden at the fringes and white near the lips, save for the nicotine stain from his perpetual cigar – all these were as well known in London as in Africa, and could only be associated with the tremendous personality of Dr. Leon Sterndale, the great lion-hunter and explorer.
We had heard of his presence in the district and had once or twice caught sight of his tall figure upon the moorland paths. He made no advances to us, however, nor would we have dreamed of doing so to him, as it was well known that it was his love of seclusion which caused him to spend the greater part of the intervals between his journeys in a small bungalow buried in the lonely wood of Beauchamp Arriance. Here, amid his books and his maps, he lived an absolutely lonely life, attending to his own simple wants and paying little apparent heed to the affairs of his neighbors.
It was a surprise to me, therefore, to hear him asking Holmes in an eager voice whether he had made any advance in his reconstruction of this mysterious episode. "The county police are utterly at fault," said he, "but perhaps your wider experience has suggested some conceivable explanation. My only claim to being taken into your confidence is that during my many residences here I have come to know this family of Tregennis very well – indeed, upon my Cornish mother's side I could call them cousins – and their strange fate has naturally been a great shock to me. I may tell you that I had got as far as Plymouth upon my way to Africa, but the news reached me this morning, and I came straight back again to help in the inquiry."
Holmes raised his eyebrows. "Did you lose your boat through it?"
"I will take the next."
"Dear me! that is friendship indeed."
"I tell you they were relatives."
"Quite so – cousins of your mother. Was your baggage aboard the ship?"
"Some of it, but the main part at the hotel."
"I see. But surely this event could not have found its way into the Plymouth morning papers."
"No, sir; I had a telegram."
"Might I ask from whom?"
A shadow passed over the gaunt face of the explorer. "You are very inquisitive, Mr. Holmes."
"It is my business."
With an effort Dr. Sterndale recovered his ruffled composure. "I have no objection to telling you," he said. "It was Mr. Roundhay, the vicar, who sent me the telegram which recalled me."
"Thank you," said Holmes. "I may say in answer to your original question that I have not cleared my mind entirely on the subject of this case, but that I have every hope of reaching some conclusion. It would be premature to say more."
"Perhaps you would not mind telling me if your suspicions point in any particular direction?"
"No, I can hardly answer that."
"Then I have wasted my time and need not prolong my visit." The famous doctor strode out of our cottage in considerable ill-humor, and within five minutes Holmes had followed him. I saw him no more until the evening, when he returned with a slow step and haggard face which assured me that he had made no great progress with his investigation.
He glanced at a telegram which awaited him and threw it into the grate. "From the Plymouth hotel, Watson," he said. "I learned the name of it from the vicar, and I wired to mak
e certain that Dr. Leon Stemdale's account was true. It appears that he did indeed spend last night there, and that he has actually allowed some of his baggage to go on to Africa, while he returned to be present at this investigation. What do you make of that, Watson?"
"He is deeply interested."
"Deeply interested – yes. There is a thread here which we have not yet grasped and which might lead us through the tangle. Cheer up, Watson, for I am very sure that our material has not yet all come to hand. When it does we may soon leave our difficulties behind us."
Little did I think how soon the words of Holmes would be realized, or how strange and sinister would be that new development which opened up an entirely fresh line of investigation.
I was shaving at my window in the morning when I heard the rattle of hoofs and, looking up, saw a dogcart coming at a gallop down the road. It pulled up at our door, and our friend, the vicar, sprang from it and rushed up our garden path. Holmes was already dressed, and we hastened down to meet him.
Our visitor was so excited that he could hardly articulate, but at last in gasps and bursts his tragic story came out of him. "We are devil-ridden, Mr. Holmes! My poor parish is devil-ridden!" he cried. "Satan himself is loose in it! We are given over into his hands!" He danced about in his agitation, a ludicrous object if it were not for his ashy face and startled eyes. Finally he shot out his terrible news. "Mr. Mortimer Tregennis died during the night, and with exactly the same symptoms as the rest of his family."
Holmes sprang to his feet, all energy in an instant. "Can you fit us both into your dogcart?"
"Yes, I can."
"Then, Watson, we will postpone our breakfast. Mr. Roundhay, we are entirely at your disposal. Hurry – hurry, before things get disarranged. "
The lodger occupied two rooms at the vicarage, which were in an angle by themselves, the one above the other. Below was a large sitting-room; above, his bedroom. They looked out upon a croquet lawn which came up to the windows. We had arrived before the doctor or the police, so that everything was absolutely undisturbed. Let me describe exactly the scene as we saw it upon that misty March morning. It has left an impression which can never be effaced from my mind.
The atmosphere of the room was of a horrible and depressing stuffiness. The servant who had first entered had thrown up the window, or it would have been even more intolerable. This might partly be due to the fact that a lamp stood flaring and smoking on the center table. Beside it sat the dead man, leaning back in his chair, his thin beard projecting, his spectacles pushed up on to his forehead, and his lean dark face turned towards the window and twisted into the same distortion of terror which had marked the features of his dead sister. His limbs were convulsed and his fingers contorted as though he had died in a very paroxysm of fear. He was fully clothed, though there were signs that his dressing had been done in a hurry. We had already learned that his bed had been slept in, and that the tragic end had come to him in the early morning.
One realized the red-hot energy which underlay Holmes's phlegmatic exterior when one saw the sudden change which came over him from the moment that he entered the fatal apartment. In an instant he was tense and alert, his eyes shining, his face set, his limbs quivering with eager activity. He was out on the lawn, in through the window, round the room, and up into the bedroom, for all the world like a dashing foxhound drawing a cover. In the bedroom he made a rapid cast around and ended by throwing open the window, which appeared to give him some fresh cause for excitement, for he leaned out of it with loud ejaculations of interest and delight. Then he rushed down the stair, out through the open window, threw himself upon his face on the lawn, sprang up and into the room once more, all with the energy of the hunter who is at the very heels of his quarry. The lamp, which was an ordinary standard, he examined with minute care, making certain measurements upon its bowl. He carefully scrutinized with his lens the tale shield which covered the top of the chimney and scraped off some ashes which adhered to its upper surface, putting some of them into an envelope, which he placed in his pocketbook.
Finally, just as the doctor and the official police put in an appearance, he beckoned to the vicar and we all three went out upon the lawn. "I am glad to say that my investigation has not been entirely barren," he remarked. "I cannot remain to discuss the matter with the police, but I should be exceedingly obliged, Mr. Roundhay, if you would give the inspector my compliments and direct his attention to the bedroom window and to the sitting-room lamp. Each is suggestive, and together they are almost conclusive. If the police would desire further information I shall be happy to see any of them at the cottage. And now, Watson, I think that, perhaps, we shall be better employed elsewhere."
It may be that the police resented the intrusion of an amateur, or that they imagined themselves to be upon some hopeful line of investigation; but it is certain that we heard nothing from them for the next two days. During this time Holmes spent some of his time smoking and dreaming in the cottage; but a greater portion in country walks which he undertook alone, returning after many hours without remark as to where he had been. One experiment served to show me the line of his investigation. He had bought a lamp which was the duplicate of the one which had burned in the room of Mortimer Tregennis on the morning of the tragedy. This he filled with the same oil as that used at the vicarage, and he carefully timed the period which it would take to be exhausted. Another experiment which he made was of a more unpleasant nature, and one which I am not likely ever to forget.
"You will remember, Watson," he remarked one afternoon, "that there is a single common point of resemblance in the varying reports which have reached us. This concerns the effect of the atmosphere of the room in each case upon those who had first entered it. You will recollect that Mortimer Tregennis, in describing the episode of his last visit to his brother's house, remarked that the doctor on entering the room fell into a chair? You had forgotten? Well, I can answer for it that it was so. Now, you will remember also that Mrs. Porter, the housekeeper, told us that she herself fainted upon entering the room and had afterwards opened the window. In the second case – that of Mortimer Tregennis himself – you cannot have forgotten the horrible stuffiness of the room when we arrived, though the servant had thrown open the window. That servant, I found upon inquiry, was so ill that she had gone to her bed. You will admit, Watson, that these facts are very suggestive. In each case there is evidence of a poisonous atmosphere. In each case, also, there is combustion going on in the room – in the one case a fire, in the other a lamp. The fire was needed, but the lamp was lit – as a comparison of the oil consumed will show – long after it was broad daylight. Why? Surely because there is some connection between three things – the burning, the stuffy atmosphere, and, finally, the madness or death of those unfortunate people. That is clear, is it not?"
"It would appear so."
"At least we may accept it as a working hypothesis. We will suppose, then, that something was burned in each case which produced an atmosphere causing strange toxic effects. Very good. In the first instance – that of the Tregennis family – this substance was placed in the fire. Now the window was shut, but the fire would naturally carry fumes to some extent up the chimney. Hence one would expect the effects of the poison to be less than in the second case, where there was less escape for the vapor. The result seems to indicate that it was so, since in the first case only the woman, who had presumably the more sensitive organism, was killed, the others exhibiting that temporary or permanent lunacy which is evidently the first effect of the drug. In the second case the result was complete. The facts, therefore, seem to bear out the theory of a poison which worked by combustion.
"With this train of reasoning in my head I naturally looked about in Mortimer Tregennis's room to find some remains of this substance. The obvious place to look was the talc shield or smoke-guard of the lamp. There, sure enough, I perceived a number of flaky ashes, and round the edges a fringe of brownish powder, which had not yet been consumed. Half
of this I took, as you saw, and I placed it in an envelope."
"Why half, Holmes?"
"It is not for me, my dear Watson, to stand in the way of the official police force. I leave them all the evidence which I found. The poison still remained upon the talc had they the wit to find it. Now, Watson, we will light our lamp; we will, however, take the precaution to open our window to avoid the premature decease of two deserving members of society, and you will seat yourself near that open window in an armchair unless, like a sensible man, you determine to have nothing to do with the affair. Oh, you will see it out, will you? I thought I knew my Watson. This chair I will place opposite yours, so that we may be the same distance from the poison and face to face. The door we will leave ajar. Each is now in a position to watch the other and to bring the experiment to an end should the symptoms seem alarming. Is that all clear? Well, then, I take our powder – or what remains of it – from the envelope, and I lay it above the burning lamp. So! Now, Watson, let us sit down and await developments."
They were not long in coming. I had hardly settled in my chair before I was conscious of a thick, musky odor, subtle and nauseous. At the very first whiff of it my brain and my imagination were beyond all control. A thick, black cloud swirled before my eyes, and my mind told me that in this cloud, unseen as yet, but about to spring out upon my appalled senses, lurked all that was vaguely horrible, all that was monstrous and inconceivably wicked in the universe. Vague shapes swirled and swam amid the dark cloud-bank, each a menace and a warning of something coming, the advent of some unspeakable dweller upon the threshold, whose very shadow would blast my soul. A freezing horror took possession of me. I felt that my hair was rising, that my eyes were protruding, that my mouth wag opened, and my tongue like leather. The turmoil within my brain was such that something must surely snap. I tried to scream and was vaguely aware of some hoarse croak which was my own voice, but distant and detached from myself.
