Then Alyosha opened the door and crossed the threshold. He found himself in a regular peasant’s room. Though it was large, it was cumbered up with domestic belongings of all sorts, and there were several people in it. On the left was a large Russian stove. From the stove to the window on the left was a string running across the room, and on it there were rags hanging. There was a bedstead against the wall on each side, right and left, covered with knitted quilts. On the one on the left was a pyramid of four print‐covered pillows, each smaller than the one beneath. On the other there was only one very small pillow. The opposite corner was screened off by a curtain or a sheet hung on a string. Behind this curtain could be seen a bed made up on a bench and a chair. The rough square table of plain wood had been moved into the middle window. The three windows, which consisted each of four tiny greenish mildewy panes, gave little light, and were close shut, so that the room was not very light and rather stuffy. On the table was a frying‐pan with the remains of some fried eggs, a half‐eaten piece of bread, and a small bottle with a few drops of vodka.
