on his bench and I could not get to sleep, either. Whether his stories had excited my nerves or the strange night had fevered my blood--anyway, I could not go to sleep. All inclination for sleep disappeared at last and I lay with my eyes open and thought, thought intensely, goodness knows of what; of most senseless trifles--as always happens when one is sleepless. Turning from side to side I stretched out my hands.... My finger hit one of the beams of the wall. It emitted a faint but resounding, and as it were, prolonged note.... I must have struck a hollow place. I tapped again ... this time on purpose. The same sound was repeated. I knocked again.... All at once Tyeglev raised his head. "Ridel!" he said, "do you hear? Someone is knocking under the window." I pretended to be asleep. The fancy suddenly took me to play a trick at the expense of my "fatal" friend. I could not sleep, anyway. He let his head sink on the pillow. I waited for a little and again knocked three times in succession. Tyeglev sat up again and listened. I tapped again. I was lying facing him but he could not see my hand.... I put it behind me under the bedclothes. "Ridel!" cried Tyeglev. I did not answer. "Ridel!" he repeated loudly. "Ridel!" "Eh? What is it?" I said as though just waking up. "Don't you hear, someone keeps knocking under the window, wants to come in, I suppose." "Some passer-by," I muttered. "Then we must let him in or find out who it is." But I made no answer, pretending to be asleep. Several minutes passed.... I tapped again. Tyeglev sat up at once and listened. "Knock ... knock ... knock! Knock ... knock ... knock!"
