Crime and Punishment by Fyodor Dostoyevksy:
He had spoken the truth, moreover, when he blurted out in his drunken talk on the stairs that Praskovya Pavlovna, Raskolnikov’s eccentric landlady, would be jealous of Pulcheria Alexandrovna as well as of Avdotya Romanovna on his account. Although Pulcheria Alexandrovna was forty-three, her face still retained traces of her former beauty; she looked much younger than her age, indeed, which is almost always the case with women who retain serenity of spirit, sensitiveness and pure sincere warmth of heart to old age. We may add in parenthesis that to preserve all this is the only means of retaining beauty to old age. Her hair had begun to grow grey and thin, there had long been little crow’s foot wrinkles round her eyes, her cheeks were hollow and sunken from anxiety and grief, and yet it was a handsome face. She was Dounia over again, twenty years older, but without projecting underlip. Pulcheria Alexandrovna was emotional, but not sentimental, timid and yielding, but only to a certain point. She could give way and accept a great deal even of what was contrary to her convictions, but there was a certain barrier fixed by honesty, principle and the deepest convictions which nothing would induce her to cross.
Exactly twenty minutes after Razumihin’s departure, there came two subdued but hurried knocks at the door: he had come back.
