Fyodor Dostoevsky

“ Smerdyakov, exhausted by his fit, lay motionless in the next room. Marfa Ignatyevna did not stir. "The stuff's been too much for the woman," Grigory thought, glancing at her, and groaning, he went out on the steps. No doubt he only intended to look out from the steps, for he was hardly able to walk, the pain in his back and his right leg was intolerable. But he suddenly remembered that he had not locked the little gate into the garden that evening. He was the most punctual and precise of men, a man who adhered to an unchangeable routine, and habits that lasted for years. ”

“ He knocked the signal the old man had agreed upon with Smerdyakov, twice slowly and then three times more quickly, the signal that meant "Grushenka is here!"
The old man started, jerked up his head, and, jumping up quickly, ran to the window. Mitya slipped away into the shadow. Fyodor Pavlovitch opened the window and thrust his whole head out.
"Grushenka, is it you? Is it you?" he said, in a sort of trembling half-whisper. "Where are you, my angel, where are you?" He was fearfully agitated and breathless.
"He's alone," Mitya decided. ”

“ Fyodor Pavlovitch moved away from the window. "He's looking for her out of the window, so she's not there. Why should he stare out into the dark? He's wild with impatience."... Mitya slipped back at once, and fell to gazing in at the window again. The old man was sitting down at the table, apparently disappointed. At last he put his elbow on the table, and laid his right cheek against his hand. Mitya watched him eagerly. ”
