Sherlock Holmes learned back in his armchair. "Observation shows me that you have been to the Wigmore Street Post-Office this morning, but deduction lets me know that when there, you dispatched a telegram.
"Right!" said I. "Right on both points! But I confess that I don't see how you arrived at it. It was a sudden thought, and I have mentioned it to no one."
"It is simplicity itself," he remarked, chucking at my surprise. "Observation tells me that you have a little reddish mould stuck to your shoe. Just opposite the Wigmore Street Post-Office they have taken up the pavement and thrown up some earth which lies in such a way that it is difficult to avoid stepping on it in entering. The earth is of this peculiar reddish tint which is found, as far as I know, nowhere else in the neighbourhood. So much is observation. The rest is deduction."
"How, then, did you deduce the telegram?"
"Why, of course I knew that you had not written a letter, since I sat opposite to you all morning. I see also in your open desk there that you have a sheet of stamps and a thick bundle of postcards. What could you go into the post-office for, then, but to send a wire? Eliminate all other factors, and the one which remains must be the truth."
