"This midnight episode, so odd and yet so trivial in itself, fired me with more curiosity than ever about my fellow-lodger. It also made me connect him in my mind with a sense of fear and distrust. I never saw him, yet I was often, and uncomfortably, aware of his presence in the upper regions of that gloomy lodging-house. Smith and his secret mode of life and mysterious pursuits, somehow contrived to awaken in my being a line of reflection that disturbed my comfortable condition of ignorance. I never saw him, as I have said, and exchanged no sort of communication with him, yet it seemed to me that his mind was in contact with mine, and some of the strange forces of his atmosphere filtered through into my being and disturbed my equilibrium. Those upper floors became haunted for me after dark, and, though outwardly our lives never came into contact, I became unwillingly involved in certain pursuits on which his mind was centred. I felt that he was somehow making use of me against my will, and by methods which passed my comprehension.
"I was at that time, moreover, in the heavy, unquestioning state of materialism which is common to medical students when they begin to understand something of the human anatomy and nervous system, and jump at once to the conclusion that they control the universe and hold in their forceps the last word of life and death. I 'knew it all,' and regarded a belief in anything beyond matter as the wanderings of weak, or at best, untrained minds. And this condition of mind, of course, added to the strength of this upsetting fear which emanated from the floor below and began slowly to take possession of me.
"Though I kept no notes of the subsequent events in this matter, they made too deep an impression for me ever to forget the sequence in which they occurred. Without difficulty I can recall the next step in the adventure with Smith, for adventure it rapidly grew to be."
The doctor stopped a moment and laid his pipe on the table behind him before continuing. The fire had burned low, and no one stirred to poke it. The silence in the great hall was so deep that when the speaker's pipe touched the table the sound woke audible echoes at the far end among the shadows.
"One evening, while I was reading, the door of my room opened and Smith came in. He made no attempt at ceremony. It was after ten o'clock and I was tired, but the presence of the man immediately galvanised me into activity. My attempts at ordinary politeness he thrust on one side at once, and began asking me to vocalise, and then pronounce for him, certain Hebrew words; and when this was done he abruptly inquired if I was not the fortunate possessor of a very rare Rabbinical Treatise, which he named.
"How he knew that I possessed this book puzzled me exceedingly; but I was still more surprised to see him cross the room and take it out of my book-shelf almost before I had had time to answer in the affirmative. Evidently he knew exactly where it was kept. This excited my curiosity beyond all bounds, and I immediately began asking him questions; and though, out of sheer respect for the man, I put them very delicately to him, and almost by way of mere conversation, he had only one reply for the lot. He would look up at me from the pages of the book with an expression of complete comprehension on his extraordinary features, would bow his head a little and say very gravely—
"'That, of course, is a perfectly proper question,'—which was absolutely all I could ever get out of him.
"On this particular occasion he stayed with me perhaps ten or fifteen minutes. Then he went quickly downstairs to his room with my Hebrew Treatise in his hand, and I heard him close and bolt his door.
"But a few moments later, before I had time to settle down to my book again, or to recover from the surprise his visit had caused me, I heard the door open, and there stood Smith once again beside my chair. He made no excuse for his second interruption, but bent his head down to the level of my reading lamp and peered across the flame straight into my eyes.
"'I hope,' he whispered, 'I hope you are never disturbed at night?'
