金边夹鼻眼镜（9）

This sort of nose is usually a short and coarse one, but there are a sufficient number of exceptions to prevent me from being dogmatic or from insisting upon this point in my description. My own face is a narrow one, and yet I find that I cannot get my eyes into the centre, or near the centre, of these glasses. Therefore the lady's eyes are set very near to the sides of the nose. You will perceive, Watson, that the glasses are concave and of unusual strength. A lady whose vision has been so extremely contracted all her life is sure to have the physical characteristics of such vision, which are seen in the forehead, the eyelids, and the shoulders.”

“Yes,” I said, “I can follow each of your arguments. I confess, however, that I am unable to understand how you arrive at the double visit to the optician.”

Holmes took the glasses in his hand.

“You will perceive,” he said, “that the clips are lined with tiny bands of cork to soften the pressure upon the nose. One of these is discoloured and worn to some slight extent, but the other is new. Evidently one has fallen off and been replaced. I should judge that the older of them has not been there more than a few months. They exactly correspond, so I gather that the lady went back to the same establishment for the second.”

“By George, it's marvellous!” cried Hopkins, in an ecstasy of admiration. “To think that I had all that evidence in my hand and never knew it! I had intended, however, to go the round of the London opticians.”

“Of course you would. Meanwhile, have you anything more to tell us about the case?”

“Nothing, Mr. Holmes. I think that you know as much as I do now—probably more. We have had inquiries made as to any stranger seen on the country roads or at the railway station. We have heard of none. What beats me is the utter want of all object in the crime. Not a ghost of a motive can anyone suggest.”
