He had perhaps been asking himself that question a quarter of an hour before, but now he spoke helplessly, hardly knowing what he said and feeling a continual tremor all over.

"Oh, how you are suffering!" she muttered in distress, looking intently at him.

"It's all nonsense.... Listen, Sonia." He suddenly smiled, a pale helpless smile for two seconds. "You remember what I meant to tell you yesterday?"

Sonia waited uneasily.

"I said as I went away that perhaps I was saying good-bye for ever, but that if I came to-day I would tell you who... who killed Lizaveta."

She began trembling all over.

"Well, here I've come to tell you."

"Then you really meant it yesterday?" she whispered with difficulty. "How do you know?" she asked quickly, as though suddenly regaining her reason.

Sonia's face grew paler and paler, and she breathed painfully.

"I know."

She paused a minute.

"Have they found him?" she asked timidly.

"No."

"Then how do you know about _it_?" she asked again, hardly audibly and again after a minute's pause.

He turned to her and looked very intently at her.

"Guess," he said, with the same distorted helpless smile.

A shudder passed over her.

"But you... why do you frighten me like this?" she said, smiling like a child.

"I must be a great friend of _his_... since I know," Raskolnikov went on, still gazing into her face, as though he could not turn his eyes away. "He... did not mean to kill that Lizaveta... he... killed her accidentally.... He meant to kill the old woman when she was alone and he went there... and then Lizaveta came in... he killed her too."

Another awful moment passed. Both still gazed at one another.

"You can't guess, then?" he asked suddenly, feeling as though he were flinging himself down from a steeple.

"N-no..." whispered Sonia.

"Take a good look."
