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.
