“Indeed! That is interesting,” said Holmes.

“Oh, yes! In a hundred other ways he has helped him. Everybody about here speaks of his kindness to him.”

“Really! Does it not strike- you as a little singular that this McCarthy, who appears to have had little of his own, and to have been under such obligations to Turner, should still talk of marrying his son to Turner’s daughter, who is, presumably, heiress to the estate, and that in such a very cocksure manner, as if it were merely a case of a proposal and all else would follow? It is the more strange, since we know that Turner himself was averse to the idea. The daughter told us as much. Do you not deduce something from that?”

“We have got to the deductions and the inferences,” said Lestrade, winking at me. “I find it hard enough to tackle facts, Holmes, without flying away after theories and fancies.”

“You are right,” said Holmes demurely; “you do find it very hard to tackle the facts.”

“Anyhow, I have grasped one fact which you seem to find it difficult to get hold of,” replied Lestrade with some warmth.

“And that is —”

“That McCarthy senior met his death from McCarthy junior and that all theories to the contrary are the merest moonshine.”

“Well, moonshine is a brighter thing than fog,” said Holmes, laughing. “But I am very much mistaken mistaken if this is not Hatherley Farm upon the left.”

“Yes, that is it.” It was a widespread, comfortable-looking building, two-storied, slate-roofed, with great yellow blotches of lichen upon the gray walls. The drawn blinds and the smokeless chimneys, however, gave it a stricken look, as though the weight of this horror still lay heavy upon it. We called at the door, when the maid, at Holmes’s request, showed us the boots which her master wore at the time of his death, and also a pair of the son’s, though not the pair which he had then had. Having measured these very carefully from seven or eight different points, Holmes desired to be led to the court-yard, from which we all followed the winding track which led to Boscombe Pool.

Sherlock Holmes was transformed when he was hot upon such a scent as this. Men who had only known the quiet thinker and logician of Baker Street would have failed to recognize him. His face flushed and darkened. His brows were drawn into two hard black lines, while his eyes shone out from beneath them with a steely glitter. His face was bent downward, his shoulders bowed, his lips compressed, and the veins stood out like whipcord in his long, sinewy neck. His nostrils seemed to dilate with a purely animal lust for the chase, and his mind was so absolutely concentrated upon the matter before him that a question or remark fell unheeded upon his ears, or, at the most, only provoked a quick, impatient snarl in reply. Swiftly and silently he made his way along the track which ran through the meadows, and so by way of the woods to the Boscombe Pool. It was damp, marshy ground, as is all that district, and there were marks of many feet, both upon the path and amid the short grass which bounded it on either side. Sometimes Holmes would hurry on, sometimes stop dead, and once he made quite a little detour into the meadow. Lestrade and I walked behind him, the detective indifferent and contemptuous, while I watched my friend with the interest which sprang from the conviction that every one of his actions was directed towards a definite end.

The crowd, nonplussed, now began to argue and shout and whistle. The voices rose in pitch and derision. Steam was getting up. There hung the flag. The procession crowded forward and filled the street in a mass below. All the rest of the street was empty and shut up. And still hung the showy rag, red and white and green, up aloft.

Suddenly there was a lull—then shouts, half–encouraging, half– derisive. And Aaron saw a smallish–black figure of a youth, fair– haired, not more than seventeen years old, clinging like a monkey to the front of the house, and by the help of the heavy drain–pipe and the stone–work ornamentation climbing up to the stone ledge that ran under ground–floor windows, up like a sudden cat on to the projecting footing. He did not stop there, but continued his race like some frantic lizard running up the great wall–front, working away from the noise below, as if in sheer fright. It was one unending wriggling movement, sheer up the front of the impassive, heavy stone house.

The flag hung from a pole under one of the windows of the top storey— the third floor. Up went the wriggling figure of the possessed youth. The cries of the crowd below were now wild, ragged ejaculations of excitement and encouragement. The youth seemed to be lifted up, almost magically on the intense upreaching excitement of the massed men below. He passed the ledge of the first floor, like a lizard he wriggled up and passed the ledge or coping of the second floor, and there he was, like an upward–climbing shadow, scrambling on to the coping of the third floor. The crowd was for a second electrically still as the boy rose there erect, cleaving to the wall with the tips of his fingers.

But he did not hesitate for one breath. He was on his feet and running along the narrow coping that went across the house under the third floor windows, running there on that narrow footing away above the street, straight to the flag. He had got it—he had clutched it in his hand, a handful of it. Exactly like a great flame rose the simultaneous yell of the crowd as the boy jerked and got the flag loose. He had torn it down. A tremendous prolonged yell, touched with a snarl of triumph, and searing like a puff of flame, sounded as the boy remained for one moment with the flag in his hand looking down at the crowd below. His face was odd and elated and still. Then with the slightest gesture he threw the flag from him, and Aaron watched the gaudy remnant falling towards the many faces, whilst the noise of yelling rose up unheard.

There was a great clutch and hiss in the crowd. The boy still stood unmoved, holding by one hand behind him, looking down from above, from his dangerous elevation, in a sort of abstraction.

And the next thing Aaron was conscious of was the sound of trumpets. A sudden startling challenge of trumpets, and out of nowhere a sudden rush of grey–green carabinieri battering the crowd wildly with truncheons. It was so sudden that Aaron heard nothing any more. He only saw.
