"The man's hair was exceedingly fine, and the lines about his nose and mouth were cut as with a delicate steel instrument in wax. His eyes I have left to the last. They were large and quite changeable, not in colour only, but in character, size, and shape. Occasionally they seemed the eyes of someone else, if you can understand what I mean, and at the same time, in their shifting shades of blue, green, and a nameless sort of dark grey, there was a sinister light in them that lent to the whole face an aspect almost alarming. Moreover, they were the most luminous optics I think I have ever seen in any human being. "There, then, at the risk of a wearisome description, is Smith as I saw him for the first time that winter's evening in my shabby student's rooms in Edinburgh. And yet the real part of him, of course, I have left untouched, for it is both indescribable and un-get-atable. I have spoken already of an atmosphere of warning and aloofness he carried about with him. It is impossible further to analyse the series of little shocks his presence always communicated to my being; but there was that about him which made me instantly on the _qui vive_ in his presence, every nerve alert, every sense strained and on the watch. I do not mean that he deliberately suggested danger, but rather that he brought forces in his wake which automatically warned the nervous centres of my system to be on their guard and alert. "Since the days of my first acquaintance with this man I have lived through other experiences and have seen much I cannot pretend to explain or understand; but, so far in my life, I have only once come across a human being who suggested a disagreeable familiarity with unholy things, and who made me feel uncanny and 'creepy' in his presence; and that unenviable individual was Mr. Smith. "What his occupation was during the day I never knew. I think he slept until the sun set. No one ever saw him on the stairs, or heard him move in his room during the day. He was a creature of the shadows, who apparently preferred darkness to light. Our landlady either knew nothing, or would say nothing. At any rate she found no fault, and I have since wondered often by what magic this fellow was able to convert a common landlady of a common lodging-house into a discreet and uncommunicative person. This alone was a sign of genius of some sort. "'He's been here with me for years--long before you come, an' I don't interfere or ask no questions of what doesn't concern me, as long as people pays their rent,' was the only remark on the subject that I ever succeeded in winning from that quarter, and it certainly told me nothing nor gave me any encouragement to ask for further information. "Examinations, however, and the general excitement of a medical student's life for a time put Mr. Smith completely out of my head. For a long period he did not call upon me again, and for my part, I felt no courage to return his unsolicited visit.
