When with a preoccupied face she touched the jelly with a spoon and then began languidly eating it, sipping milk, and he heard her swallowing, he was possessed by such an overwhelming aversion that it made his head tingle. He recognised that such a feeling would be an insult even to a dog, but he was angry, not with himself but with Nadyezhda Fyodorovna, for arousing such a feeling, and he understood why lovers sometimes murder their mistresses. He would not murder her, of course, but if he had been on a jury now, he would have acquitted the murderer. "
