He shrugged his shoulders and lay down on the couch.
I went out and called James Perry and instructed him what to do.
He went into the room, crossed to the window and stood there a moment with his shadow showing plainly on the blind. Then he pulled up the blind, and turned as if in obedience to some order from Karl. Next he threw the large window open and stepped out on to the gravel, and stood there long enough for any one who might be watching to have a full view of the interior of the room.
"No, sir, it is not raining," he said, and came back through the window making as if to close and fasten it. He stopped in the act of doing this, and partly opened it again, as if obeying orders from Karl.
"No, it's not cold, sir, but it will be draughty," he said.
Then with a shrug of the shoulders he left it open and turned away. Taking a rug from one of the lounges he threw it over Karl, taking pains to tuck it in carefully; and then stood back as if asking for any further orders.
"Good-night, sir," he said, and crossing to the door, he switched out the light.
Immediately this was done, I ran in again, hurried Karl out of the room, laid a sofa pillow on the couch, and arranged the rug over it as James had done. Then I recrossed the room and waited, my fingers close to the electric light switch, to see if the trap was laid cleverly enough to deceive the man I was expecting. I stood in a dark corner by the door, partly concealed by a screen, where I could see the whole room and all that occurred.
My eyes soon grew accustomed to the comparative darkness. The moon was shining brilliantly, and the slanting rays through one of the windows fell right across one end of the couch on which Karl had been lying. They revealed the lower half of what appeared to be the huddled figure of the sleeper, the upper half being wrapped in deep shadow.
The house was all silent. I had heard Karl go upstairs, James Perry being with him; and had caught the latter's careful tread as he came down again to the hall where I had told him to wait, in case I should need and call him.
