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 centre 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 talc 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."
