“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.
“Of course it has moved,” said he. “Am I such a farcical bungler, Watson, that I should erect an obvious dummy, and expect that some of the sharpest men in Europe would be deceived by it? We have been in this room two hours, and Mrs. Hudson has made some change in that figure eight times, or once in every quarter of an hour. She works it from the front, so that her shadow may never be seen. Ah!” He drew in his breath with a shrill, excited intake. In the dim light I saw his head thrown forward, his whole attitude rigid with attention. Outside the street was absolutely deserted. Those two men might still be crouching in the doorway, but I could no longer see them. All was still and dark, save only that brilliant yellow screen in front of us with the black figure outlined upon its centre. Again in the utter silence I heard that thin, sibilant note which spoke of intense suppressed excitement. 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.
