Beside himself with shame and despair, the utterly ruined though perfectly just Mr. Golyadkin dashed headlong away, wherever fate might lead him; but with every step he took, with every thud of his foot on the granite of the pavement, there leapt up as though out of the earth a Mr. Golyadkin precisely the same, perfectly alike, and of a revolting depravity of heart. And all these precisely similar Golyadkins set to running after one another as soon as they appeared, and stretched in a long chain like a file of geese, hobbling after the real Mr. Golyadkin, so there was nowhere to escape from these duplicates — so that Mr. Golyadkin, who was in every way deserving of compassion, was breathless with terror; so that at last a terrible multitude of duplicates had sprung into being; so that the whole town was obstructed at last by duplicate Golyadkins, and the police officer, seeing such a breach of decorum, was obliged to seize all these duplicates by the collar and to put them into the watch-house, which happened to be beside him . . . Numb and chill with horror, our hero woke up, and numb and chill with horror felt that his waking state was hardly more cheerful . . . It was oppressive and harrowing . . . He was overcome by such anguish that it seemed as though some one were gnawing at his heart.
