"How do I explain them? What is there to explain? It's clear. At any rate, the direction in which explanation is to be sought is clear, and the jewel-case points to it. The real murderer dropped those ear-rings. The murderer was upstairs, locked in, when Koch and Pestryakov knocked at the door. Koch, like an ass, did not stay at the door; so the murderer popped out and ran down, too; for he had no other way of escape. He hid from Koch, Pestryakov and the porter in the flat when Nikolay and Dmitri had just run out of it. He stopped there while the porter and others were going upstairs, waited till they were out of hearing, and then went calmly downstairs at the very minute when Dmitri and Nikolay ran out into the street and there was no one in the entry; possibly he was seen, but not noticed. There are lots of people going in and out. He must have dropped the ear-rings out of his pocket when he stood behind the door, and did not notice he dropped them, because he had other things to think of. The jewel-case is a conclusive proof that he did stand there.... That's how I explain it."

"Too clever! No, my boy, you're too clever. That beats everything."

"But, why, why?"

"Why, because everything fits too well... it's too melodramatic."

"A-ach!" Razumihin was exclaiming, but at that moment the door opened and a personage came in who was a stranger to all present.
