two men who appeared to be sheltering themselves from the wind in the doorway of a house some distance up the street. I tried to draw my companion's attention to them, but he gave a little ejaculation of impatience and continued to stare into the street. More than once he fidgeted with his feet and tapped rapidly with his fingers upon the wall. It was evident to me that he was becoming uneasy and that his plans were not working out altogether as he had hoped. At last, as midnight approached and the street gradually cleared, he paced up and down the room in uncontrollable agitation. I was about to make some remark to him when I raised my eyes to the lighted window and again experienced almost as great a surprise as before. I clutched Holmes's arm and pointed upwards.
"The shadow has moved!" I cried.
It was, indeed, no longer the profile, but the back, which was turned towards us.
Three years had certainly not smoothed the asperities of his temper or his impatience with a less active intelligence than his own.

An instant later he pulled me back into the blackest corner of the room, and I felt his warning hand upon my lips. The fingers which clutched me were quivering. Never had I known my friend more moved, and yet the dark street still stretched lonely and motionless before us.

"THE LIGHT OF THE STREET FELL FULL UPON HIS FACE."
But suddenly I was aware of that which his keener senses had already distinguished. A low, stealthy sound came to my ears, not from the direction of Baker Street, but from the back of the very house in which we lay concealed. A door opened and shut. An instant later steps crept down the passage—steps which were meant to be silent, but which reverberated harshly through the empty house. Holmes crouched back against the wall and I did the same, my hand closing upon the handle of my
