There intervened one awful minute of pure shock, when the soul was in darkness.

Out of this shock Aaron felt himself issuing amid a mass of terrible sensations: the fearful blow of the explosion, the noise of glass, the hoarse howl of people, the rushing of men, the sudden gulf, the awful gulfing whirlpool of horror in the social life.

He stood in agony and semi–blindness amid a chaos. Then as he began to recover his consciousness, he found himself standing by a pillar some distance from where he had been sitting: he saw a place where tables and chairs were all upside down, legs in the air, amid debris of glass and breakage: he saw the cafe almost empty, nearly everybody gone: he saw the owner, or the manager, advancing aghast to the place of debris: he saw Lilly standing not far off, white as a sheet, and as if unconscious. And still he had no idea of what had happened. He thought perhaps something had broken down. He could not understand.

Lilly began to look round. He caught Aaron’s eye. And then Aaron began to approach his friend.

“What is it?” he asked.

“A bomb,” said Lilly.

The manager, and one old waiter, and three or four youths had now advanced to the place of debris. And now Aaron saw that a man was lying there—and horror, blood was running running across the floor of the cafe. Men began now hastily to return to the place. Some seized their hats and departed again at once. But many began to crowd in— a black eager crowd of men pressing to where the bomb had burst— where the man was lying. It was rather dark, some of the lamps were broken—but enough still shone. Men surged in with that eager, excited zest of people, when there has been an accident. Grey carabinieri, and carabinieri in the cocked hat and fine Sunday uniform pressed forward officiously.

“Let us go,” said Lilly.

And he went to the far corner, where his hat hung. But Aaron looked in vain for his own hat. The bomb had fallen near the stand where he had hung it and his overcoat.

“My hat and coat?” he said to Lilly.

Lilly, not very tall, stood on tiptoe. Then he climbed on a chair and looked round. Then he squeezed past the crowd.

Aaron followed. On the other side of the crowd excited angry men were wrestling over overcoats that were mixed up with a broken marble table–top. Aaron spied his own black hat under the sofa near the wall. He waited his turn and then in the confusion pressed forward to where the coats were. Someone had dragged out his, and it lay on the floor under many feet. He managed, with a struggle, to get it from under the feet of the crowd. He felt at once for his flute. But his trampled, torn coat had no flute in its pocket. He pushed and struggled, caught sight of a section, and picked it up. But it was split right down, two silver stops were torn out, and a long thin spelch of wood was curiously torn off. He looked at it, and his heart stood still. No need to look for the rest.

He felt utterly, utterly overcome—as if he didn’t care what became of him any further. He didn’t care whether he were hit by a bomb, or whether he himself threw the next bomb, and hit somebody. He just didn’t care any more about anything in life or death. It was as if the reins of his life slipped from his hands. And he would let everything run where it would, so long as it did run.

“Circumstantial evidence is a very tricky thing,” answered Holmes thoughtfully. “It may seem to point very straight to one thing, but if you shift your own point of view a little, you may find it pointing in an equally uncompromising manner to something entirely different. It must be confessed, however, that the case looks exceedingly grave against the young man, and it is very possible that he is indeed the culprit. There are several people in the neighbourhood, however, and among them Miss Turner, the daughter of the neighbouring landowner, who believe in his innocence, and who have retained Lestrade, whom you may recollect in connection with ‘A Study in Scarlet’, to work out the case in his interest. Lestrade, being rather puzzled, has referred the case to me, and hence it is that two middle-aged gentlemen are flying westward at fifty miles an hour instead of quietly digesting their breakfasts at home.”

“I am afraid,” said I, “that the facts are so obvious that you will find little credit to be gained out of this case.”

“There is nothing more deceptive than an obvious fact,” he answered, laughing. “Besides, we may chance to hit upon some other obvious facts which may have been by no means obvious to Mr. Lestrade. You know me too well to think that I am boasting when I say that I shall either confirm or destroy his theory by means which he is quite incapable of employing, or even of understanding. To take the first example to hand, I very clearly perceive that in your bedroom the window is upon the right-hand side, and yet I question whether Mr. Lestrade would have noted even so self-evident a thing as that.”

“How on earth —”

“My dear fellow, I know you well. I know the military neatness which characterizes you. You shave every morning, and in this season you shave by the sunlight; but since your shaving is less and less complete as we get farther back on the left side, until it becomes positively slovenly as we get round the angle of the jaw, it is surely very clear that that side is less illuminated than the other. I could not imagine a man of your habits looking at himself in an equal light and being satisfied with such a result. I only quote this as a trivial example of observation and inference. Therein lies my metier, and it is just possible that it may be of some service in the investigation which lies before us. There are one or two minor points which were brought out in the inquest, and which are worth considering.”

“What are they?”

“It appears that his arrest did not take place at once, but after the return to Hatherley Farm. On the inspector of constabulary informing him that he was a prisoner, he remarked that he was not surprised to hear it, and that it was no more than his deserts. This observation of his had the natural effect of removing any traces of doubt which might have remained in the minds of the coroner’s jury.”

“It was a confession,” I ejaculated.
