Passage: Hanna receives a life sentence for her admitted leadership role in the church deaths, while the other defendants are sentenced to four years and three months each. Michael (Ralph Fiennes), meanwhile, marries, has a daughter, and divorces.  Retrieving his books from the time of his and Hanna's affair, he begins reading them into a tape recorder, which he then sends to Hanna. Eventually, she begins borrowing books from the prison library and teaches herself to read and write by following along with Michael's tapes. She starts writing back to Michael, first in brief, childlike notes, and as time goes by, her letters reflect her gradually improving literacy.
