"I come now to the body of the young man. It was found near the bureau, and just to the left of it, as marked upon that chart. The stab was on the right side of the neck and from behind forwards, so that it is almost impossible that it could have been self-inflicted."
"Unless he fell upon the knife," said Holmes.
"Exactly. The idea crossed my mind. But we found the knife some feet away from the body, so that seems impossible. Then, of course, there are the man's own dying words. And, finally, there was this very important piece of evidence which was found clasped in the dead man's right hand."
From his pocket Stanley Hopkins drew a small paper packet. He unfolded it and disclosed a golden pince-nez, with two broken ends of black silk cord dangling from the end of it. "Willoughby Smith had excellent sight," he added. "There can be no question that this was snatched from the face or the person of the assassin."
Sherlock Holmes took the glasses into his hand and examined them with the utmost attention and interest. He held them on his nose, endeavoured to read through them, went to the window and stared up the street with them, looked at them most minutely in the full light of the lamp, and finally, with a chuckle, seated himself at the table and wrote a few lines upon a sheet of paper, which he tossed across to Stanley Hopkins.
"That's the best I can do for you," said he. "It may prove to be of some use."
The astonished detective read the note aloud. It ran as follows:--
"Wanted, a woman of good address, attired like a lady. She has a remarkably thick nose, with eyes which are set close upon either side of it. She has a puckered forehead, a peering expression, and probably rounded shoulders. There are indications that she has had recourse to an optician at least twice during the last few months. As her glasses are of remarkable strength and as opticians are not very numerous, there should be no difficulty in tracing her."
Holmes smiled at the astonishment of Hopkins, which must have been reflected upon my features.
"Surely my deductions are simplicity itself," said he. "It would be difficult to name any articles which afford a finer field for inference than a pair of glasses, especially so remarkable a pair as these. That they belong to a woman I infer from their delicacy, and also, of course, from the last words of the dying man. As to her being a person of refinement and well dressed, they are, as you perceive, handsomely mounted in solid gold, and it is inconceivable that anyone who wore such glasses could be slatternly in other respects. You will find that the clips are too wide for your nose, showing that the lady's nose was very broad at the base. 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."
