It was a large and bright dwelling, rather a villa than a cottage, with a considerable garden which was already, in that Cornish air, well filled with spring flowers. Towards this garden the window of the sitting-room fronted, and from it, according to Mortimer Tregennis, must have come that thing of evil which had by sheer horror in a single instant blasted their minds. Holmes walked slowly and thoughtfully among the flower-plots and along the path before we entered the porch. So absorbed was he in his thoughts, I remember, that he stumbled over the watering-pot, upset its contents, and deluged both our feet and the garden path. Inside the house we were met by the elderly Cornish housekeeper, Mrs. Porter, who, with the aid of a young girl, looked after the wants of the family. She readily answered all Holmes’s questions. She had heard nothing in the night. Her employers had all been in excellent spirits lately, and she had never known them more cheerful and prosperous. She had fainted with horror upon entering the room in the morning and seeing that dreadful company round the table. She had, when she recovered, thrown open the window to let the morning air in, and had run down to the lane, whence she sent a farm-lad for the doctor. The lady was on her bed upstairs if we cared to see her. It took four strong men to get the brothers into the asylum carriage. She would not herself stay in the house another day and was starting that very afternoon to rejoin her family at St. Ives.
We ascended the stairs and viewed the body. Miss Brenda Tregennis had been a very beautiful girl, though now verging upon middle age. Her dark, clear-cut face was handsome, even in death, but there still lingered upon it something of that convulsion of horror which had been her last human emotion. From her bedroom we descended to the sitting-room, where this strange tragedy had actually occurred. The charred ashes of the overnight fire lay in the grate. On the table were the four guttered and burned-out candles, with the cards scattered over its surface. The chairs had been moved back against the walls, but all else was as it had been the night before. Holmes paced with light, swift steps about the room; he sat in the various chairs, drawing them up and reconstructing their positions. He tested how much of the garden was visible; he examined the floor, the ceiling, and the fireplace; but never once did I see that sudden brightening of his eyes and tightening of his lips which would have told me that he saw some gleam of light in this utter darkness.
“Why a fire?” he asked once. “Had they always a fire in this small room on a spring evening?”
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?”
