Sherlock Holmes - Deductions

“Wedlock suits you,” he remarked. “I think, Watson, that you have put on seven and a half pounds since I saw you.”
“Seven!” I answered.

“Indeed, I should have thought a little more. Just a trifle more, I fancy, Watson. And in practice again, I observe. You did not tell me that you intended to go into harness.”

“Then, how do you know?”

“I see it, I deduce it. How do I know that you have been getting yourself very wet lately, and that you have a most clumsy and careless servant girl?”

“My dear Holmes,” said I, “this is too much. You would certainly have been burned, had you lived a few centuries ago. It is true that I had a country walk on Thursday and came home in a dreadful mess, but as I have changed my clothes I can’t imagine how you deduce it. As to Mary Jane, she is incorrigible, and my wife has given her notice, but there, again, I fail to see how you work it out.”

“It is simplicity itself,” said he; “my eyes tell me that on the inside of your left shoe, just where the firelight strikes it, the leather is scored by six almost parallel cuts. Obviously they have been caused by someone who has very carelessly scraped round the edges of the sole in order to remove crusted mud from it. Hence, you see, my double deduction that you had been out in vile weather, and that you had a particularly malignant bootslitting specimen of the London slavey. As to your practice, if a gentleman walks into my rooms smelling of iodoform, with a black mark of nitrate of silver upon his right forefinger, and a bulge on the right side of his top-hat to show where he has secreted his stethoscope, I must be dull, indeed, if I do not pronounce him to be an active member of the medical profession.”

“And the man who wrote the note is a German. Do you note the peculiar construction of the sentence — ‘This account of you we have from all quarters received.’ A Frenchman or Russian could not have written that. It is the German who is so uncourteous to his verbs.”

“You will excuse this mask,” continued our strange visitor. “The august person who employs me wishes his agent to be unknown to you, and I may confess at once that the title by which I have just called myself is not exactly my own.”

“I was aware of it,” said Holmes drily.

“To speak plainly, the matter implicates the great House of Ormstein, hereditary kings of Bohemia.”

“I was also aware of that,” murmured Holmes, settling himself down in his armchair and closing his eyes.

“Your Majesty had not spoken before I was aware that I was addressing Wilhelm Gottsreich Sigismond von Ormstein, Grand Duke of Cassel Felstein, and hereditary King of Bohemia.”

“Your Majesty, as I understand, became entangled with this young person, wrote her some compromising letters, and is now desirous of getting those letters back.”

“Precisely so. But how —”
