Sherlock Holmes - Deductions

“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.”

“On the contrary,” said Holmes, “it is the brightest rift which I can at present see in the clouds. However innocent he might be, he could not be such an absolute imbecile as not to see that the circumstances were very black against him. Had he appeared surprised at his own arrest, or feigned indignation at it, I should have looked upon it as highly suspicious, because such surprise or anger would not be natural under the circumstances, and yet might appear to be the best policy to a scheming man. His frank acceptance of the situation marks him as either an innocent man, or else as a man of considerable self-restraint and firmness. As to his remark about his deserts, it was also not unnatural if you consider that he stood beside the dead body of his father, and that there is no doubt that he had that very day so far forgotten his filial duty as to bandy words with him, and even, according to the little girl whose evidence is so important, to raise his hand as if to strike him. The self-reproach and contrition which are displayed in his remark appear to me to be the signs of a healthy mind rather than of a guilty on.”

“Both you and the coroner have been at some pains,” said he, “to single out the very strongest points in the young man’s favour. Don’t you see that you alternately give him credit for having too much imaginition and too little? Too little, if he could not invent a cause of quarrel which would give him the sympathy of the jury; too much, if he evolved from his own inner consciousness anything so outre as a dying reference to a rat, and the incident of the vanishing cloth.
I would call your attention very particularly to two points. One is that the murdered man had an appointment with someone at the pool, and that the someone could not have been his son, for his son was away, and he did not know when he would return. The second is that the murdered man was heard to cry ‘Cooee!’ before he knew that his son had returned.”

“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?”

“What did you go into the pool for?” he asked.
“I fished about with a rake. I thought there might be some weapon or other trace. But how on earth —”

“Here is where the party with the lodge-keeper came, and they have covered all tracks for six or eight feet round the body. But here are three separate tracks of the same feet.”

“These are young McCarthy’s feet. Twice he was walking, and once he ran swiftly, so that the soles are deeply marked and the heels hardly visible. That bears out his story. He ran when he saw his father on the ground. Then here are the father’s feet as he paced up and down. What is this, then? It is the butt-end of the gun as the son stood listening. And this? Ha, ha! What have we here? Tiptoes! tiptoes! Square, too, quite unusual boots! They come, they go, they come again — of course that was for the cloak. Now where did they come from?”

“This may interest you, Lestrade,” he remarked, holding it out. “The murder was done with it.”
“I see no marks.”
“There are none.”
“How do you know, then?”
“The grass was growing under it. It had only lain there a few days. There was no sign of a place whence it had been taken. It corresponds with the injuries. There is no sign of any other weapon.”

“And the murderer?”
“Is a tall man, left-handed, limps with the right leg, wears thick-soled shooting-boots and a gray cloak, smokes Indian cigars, uses a cigar-holder, and carries a blunt pen-knife in his pocket. There are several other indications, but these may be enough to aid us in our search.”

“Well, now, in considering this case there are two points about young McCarthy’s narrative which struck us both instantly, although they impressed me in his favour and you against him. One was the fact that his father should, according to his account, cry ‘Cooee!’ before seeing him. The other was his singular dying reference to a rat. He mumbled several words, you understand, but that was all that caught the son’s ear. Now from this double point our research must commence, and we will begin it by presuming that what the lad says is absolutely true.”
“What of this ‘Cooee!’ then?”
“Well, obviously it could not have been meant for the son. The son, as far as he knew, was in Bristol. It was mere chance that he was within earshot. The ‘Cooee!’ was meant to attract the attention of whoever it was that he had the appointment with. But ‘Cooee’ is a distinctly Australian cry, and one which is used between Australians. There is a strong presumption that the person whom McCarthy expected to meet him at Boscombe Pool was someone who had been in Australia.”
“What of the rat, then?”
Sherlock Holmes took a folded paper from his pocket and flattened it out on the table. “This is a map of the Colony of Victoria,” he said. “I wired to Bristol for it last night.” He put his hand over part of the map. “What do you read?”
“ARAT,” I read.
“And now?” He raised his hand.
“BALLARAT. “
“Quite so. That was the word the man uttered, and of which his son only caught the last two syllables. He was trying to utter the name of his murderer. So and so, of Ballarat.”

“His height I know that you might roughly judge from the length of his stride. His boots, too, might be told from their traces.”
“Yes, they were peculiar boots.”
“But his lameness?”
“The impression of his right foot was always less distinct than his left. He put less weight upon it. Why? Because he limped — he was lame.”
“But his left-handedness.”
“You were yourself struck by the nature of the injury as recorded by the surgeon at-the inquest. The blow was struck from immediately behind, and yet was upon the left side. Now, how can that be unless it were by a left-handed man?”

“I found the ash of a cigar, which my special knowledge of tobacco ashes enables me to pronounce as an Indian cigar. I have, as you know, devoted some attention to this, and written a little monograph on the ashes of 140 different varieties of pipe, cigar, and cigarette tobacco. Having found the ash, I then looked round and discovered the stump among the moss where he had tossed it. It was an Indian cigar, of the variety which are rolled in Rotterdam.”

“I could see that the end had not been in his mouth. Therefore he used a holder. The tip had been cut off, not bitten off, but the cut was not a clean one, so I deduced a blunt pen-knife.”
