Sherlock Holmes - Deductions

“No, sir, but the facts might be met speciously enough. Suppose that this man Boone had thrust Neville St. Clair through the window, there is no human eye which could have seen the deed.
“What would he do then? It would of course instantly strike him that he must get rid of the tell-tale garments. He would seize the coat, then, and be in the act of throwing it out, when it would occur to him that it would swim and not sink. He has little time, for he has heard the scuffle downstairs when the wife tried to force her way up, and perhaps he has already heard from his lascar confederate that the police are hurrying up the street. There is not an instant to be lost. He rushes to some secret hoard, where he has accumulated the fruits of his beggary, and he stuffs all the coins upon which he can lay his hands into the pockets to make sure of the coat’s sinking. He throws it out, and would have done the same with the other garments had not he heard the rush of steps below, and only just had time to close the window when the police appeared.”

“See that light among the trees? That is The Cedars, and beside that lamp sits a woman whose anxious ears have already, I have little doubt, caught the clink of our horse’s feet.”

“Mrs. St. Clair has most kindly put two rooms at my disposal, and you may rest assured that she will have nothing but a welcome for my friend and colleague.”

“Coarse writing,” murmured Holmes. “Surely this is not your husband’s writing, madam.”

“I perceive also that whoever addressed the envelope had to go and inquire as to the address.”
“How can you tell that?”
“The name, you see, is in perfectly black ink, which has dried itself. The rest is of the grayish colour, which shows that blottingpaper has been used. If it had been written straight off, and then blotted, none would be of a deep black shade. This man has written the name, and there has then been a pause before he wrote the address, which can only mean that he was not familiar with it.”

“Written in pencil upon the fly-leaf of a book, octavo size, no water-mark. Hum! Posted to-day in Gravesend by a man with a dirty thumb. Ha! And the flap has been gummed, if I am not very much in error, by a person who had been chewing tobacco.”

Let us now see the letter. Ha! there has been an enclosure here!”

“Unless this is a clever forgery to put us on the wrong scent.”

“He certainly needs a wash,” remarked Holmes. “I had an idea that he might, and I took the liberty of bringing the tools with me.”

“Let me introduce you,” he shouted, “to Mr. Neville St. Clair, of Lee, in the county of Kent.”
