"Yes, a capital thing," answered Raskolnikov, looking at him almost ironically.

"A capital thing, a capital thing," repeated Porfiry Petrovitch, as though he had just thought of something quite different. "Yes, a capital thing," he almost shouted at last, suddenly staring at Raskolnikov and stopping short two steps from him.

This stupid repetition was too incongruous in its ineptitude with the serious, brooding and enigmatic glance he turned upon his visitor.

But this stirred Raskolnikov's spleen more than ever and he could not resist an ironical and rather incautious challenge.

"Tell me, please," he asked suddenly, looking almost insolently at him and taking a kind of pleasure in his own insolence. "I believe it's a sort of legal rule, a sort of legal tradition--for all investigating lawyers--to begin their attack from afar, with a trivial, or at least an irrelevant subject, so as to encourage, or rather, to divert the man they are cross-examining, to disarm his caution and then all at once to give him an unexpected knock-down blow with some fatal question. Isn't that so? It's a sacred tradition, mentioned, I fancy, in all the manuals of the art?"

"Yes, yes.... Why, do you imagine that was why I spoke about government quarters... eh?"

And as he said this Porfiry Petrovitch screwed up his eyes and winked; a good-humoured, crafty look passed over his face. The wrinkles on his forehead were smoothed out, his eyes contracted, his features broadened and he suddenly went off into a nervous prolonged laugh, shaking all over and looking Raskolnikov straight in the face. The latter forced himself to laugh, too, but when Porfiry, seeing that he was laughing, broke into such a guffaw that he turned almost crimson, Raskolnikov's repulsion overcame all precaution; he left off laughing, scowled and stared with hatred at Porfiry, keeping his eyes fixed on him while his intentionally prolonged laughter lasted. There was lack of precaution on both sides, however, for Porfiry Petrovitch seemed to be laughing in his visitor's face and to be very little disturbed at the annoyance with which the visitor received it. The latter fact was very significant in Raskolnikov's eyes: he saw that Porfiry Petrovitch had not been embarrassed just before either, but that he, Raskolnikov, had perhaps fallen into a trap; that there must be something, some motive here unknown to him; that, perhaps, everything was in readiness and in another moment would break upon him...

He went straight to the point at once, rose from his seat and took his cap.
