What is the setting at the start of chapter 4

This chapter takes place the next night, while all of the men are off at the whorehouse spending their weeks' pay except for the feeble threesome of Crooks, Candy and Lennie. The setting is the "little shed that leaned off the wall of the barn" (73) that makes up Crooks' quarters. Steinbeck gives us a glimpse at the quiet, neat, lonesome life of the black stable buck. While Crooks is belittled and ordered around in the ranch at large, in his bunk he is sovereign; none of the other workers impede upon his living space.
