Porfiry Petrovitch took breath a moment. He had simply babbled on uttering empty phrases, letting slip a few enigmatic words and again reverting to incoherence. He was almost running about the room, moving his fat little legs quicker and quicker, looking at the ground, with his right hand behind his back, while with his left making gesticulations that were extraordinarily incongruous with his words. Raskolnikov suddenly noticed that as he ran about the room he seemed twice to stop for a moment near the door, as though he were listening.

“Is he expecting anything?”

“You are certainly quite right about it,” Porfiry began gaily, looking with extraordinary simplicity at Raskolnikov (which startled him and instantly put him on his guard); “certainly quite right in laughing so wittily at our legal forms, he-he! Some of these elaborate psychological methods are exceedingly ridiculous and perhaps useless, if one adheres too closely to the forms. Yes... I am talking of forms again. Well, if I recognise, or more strictly speaking, if I suspect someone or other to be a criminal in any case entrusted to me... you’re reading for the law, of course, Rodion Romanovitch?”

“Yes, I was...”

“Well, then it is a precedent for you for the future—though don’t suppose I should venture to instruct you after the articles you publish about crime! No, I simply make bold to state it by way of fact, if I took this man or that for a criminal, why, I ask, should I worry him prematurely, even though I had evidence against him? In one case I may be bound, for instance, to arrest a man at once, but another may be in quite a different position, you know, so why shouldn’t I let him walk about the town a bit? he-he-he! But I see you don’t quite understand, so I’ll give you a clearer example. If I put him in prison too soon, I may very likely give him, so to speak, moral support, he-he! You’re laughing?”
