Over the first few years of his imprisonment, Dufresne works in the prison laundry service, and is dogged by threats and harassment, and instances of rape by a group of sadistic homosexuals known as the "Sisters". Andy's former life as a banker and his knowledge of accounting and income taxes come to the attention of Hadley during an outdoor work detail, and after assisting the chief guard with an inheritance sum, Andy is moved to work with Brooks Hatlen in the library, where he shortly sets up a make-shift office to deal with finance related queries brought to him by various guards. His practice becomes so popular that even opposing guard teams in an inter-prison baseball match bring work to him. While working within the library, Dufresne begins to canvas support for improving the library at a relentless pace. When Andy is brutally raped again, the prison guards commit vigilante punishment against the offender, and it becomes clear that they are now protecting Dufresne from the mistreatment. When the rapist is permanently hospitalized, Andy's victimisation comes to a close.
