"Yes, in our legal practice there was a case almost exactly similar, a case of morbid psychology," Porfiry went on quickly. "A man confessed to murder and how he kept it up! It was a regular hallucination; he brought forward facts, he imposed upon everyone and why? He had been partly, but only partly, unintentionally the cause of a murder and when he knew that he had given the murderers the opportunity, he sank into dejection, it got on his mind and turned his brain, he began imagining things and he persuaded himself that he was the murderer. But at last the High Court of Appeal went into it and the poor fellow was acquitted and put under proper care. Thanks to the Court of Appeal! Tut-tut-tut! Why, my dear fellow, you may drive yourself into delirium if you have the impulse to work upon your nerves, to go ringing bells at night and asking about blood! I've studied all this morbid psychology in my practice. A man is sometimes tempted to jump out of a window or from a belfry. Just the same with bell-ringing.... It's all illness, Rodion Romanovitch! You have begun to neglect your illness. You should consult an experienced doctor, what's the good of that fat fellow? You are lightheaded! You were delirious when you did all this!"

For a moment Raskolnikov felt everything going round.

"Is it possible, is it possible," flashed through his mind, "that he is still lying? He can't be, he can't be." He rejected that idea, feeling to what a degree of fury it might drive him, feeling that that fury might drive him mad.

"I was not delirious. I knew what I was doing," he cried, straining every faculty to penetrate Porfiry's game, "I was quite myself, do you hear?"

"Yes, I hear and understand. You said yesterday you were not delirious, you were particularly emphatic about it! I understand all you can tell me! A-ach!... Listen, Rodion Romanovitch, my dear fellow. If you were actually a criminal, or were somehow mixed up in this damnable business, would you insist that you were not delirious but in full possession of your faculties? And so emphatically and persistently? Would it be possible? Quite impossible, to my thinking. If you had anything on your conscience, you certainly ought to insist that you were delirious. That's so, isn't it?"

There was a note of slyness in this inquiry. Raskolnikov drew back on the sofa as Porfiry bent over him and stared in silent perplexity at him.

"Another thing about Razumihin--you certainly ought to have said that he came of his own accord, to have concealed your part in it! But you don't conceal it! You lay stress on his coming at your instigation."

Raskolnikov had not done so. A chill went down his back.

"You keep telling lies," he said slowly and weakly, twisting his lips into a sickly smile, "you are trying again to show that you know all my game, that you know all I shall say beforehand," he said, conscious himself that he was not weighing his words as he ought. "You want to frighten me... or you are simply laughing at me..."

He still stared at him as he said this and again there was a light of intense hatred in his eyes.

"You keep lying," he said. "You know perfectly well that the best policy for the criminal is to tell the truth as nearly as possible... to conceal as little as possible. I don't believe you!"

"What a wily person you are!" Porfiry tittered, "there's no catching you; you've a perfect monomania. So you don't believe me? But still you do believe me, you believe a quarter; I'll soon make you believe the whole, because I have a sincere liking for you and genuinely wish you good."

Raskolnikov's lips trembled.

"Yes, I do," went on Porfiry, touching Raskolnikov's arm genially, "you must take care of your illness. Besides, your mother and sister are here now; you must think of them. You must soothe and comfort them and you do nothing but frighten them..."
