<P> One day, Andy hears from another prisoner, Tommy Williams, whose former cellmate had bragged about killing a rich golfer and a lawyer's wife (Andy latches onto the idea that the word "lawyer" could easily have been mixed up with "banker", the professions being similarly viewed by the uneducated public), and framing the lawyer for the crime . Upon hearing Tommy's story, Andy realizes that this evidence could possibly result in a new trial and a chance at freedom . Norton scoffs at the story, however, and as soon as possible, he makes sure Tommy is moved to another prison . Andy is too useful to Norton, and he knows details about Norton's shady dealings . Andy eventually resigns himself to the fact that his legal vindication has become nonexistent . </P> <P> Before he was sentenced to life, Andy managed to sell off his assets and invest the proceeds under a pseudonym . This alias, Peter Stevens, has a driver's license, Social Security card, and other credentials . The documents required to claim Stevens' assets and assume his identity are in a safety deposit box in a Portland bank; the key to the box is hidden under a rock along a wall lining a hay field in the small town of Buxton, not far from Shawshank . After 20 years in prison, Andy shares the information with Red, describing exactly how to find the place and how one day "Peter Stevens" will own a small seaside resort hotel in Zihuatanejo, Mexico . Red, confused about why Andy has confided this information in him, reflects on Andy's continued ability to surprise . </P> <P> One morning, after he has been incarcerated for 28 years, Andy disappears from his locked cell . After searching the prison grounds and surrounding area without finding any sign of him, the warden looks in Andy's cell and discovers that the current poster pasted to his wall (Linda Ronstadt) covers a man - sized hole . Andy had used his rock hammer not just to shape rocks, but also to slowly chip away at the wall . Once through the wall, he broke into a sewage pipe, crawled through it, emerged into a field beyond the prison's outer perimeter, and vanished . His prison uniform is found two miles away from the outfall and it is assumed that he drowned . </P> <P> A few weeks later, Red gets a blank postcard from a small Texas town near the Mexican border, and surmises that Andy crossed the border there . Shortly afterwards, Red is paroled . After nearly forty years' imprisonment, he finds the transition to life "outside" a difficult process . On the weekends, he hitchhikes to Buxton, searching for suitable hay fields from Andy's "directions". After several months of wandering the rural town roads, he finds a field with a rock wall on the correct side, with a black rock in it . Under this rock, he finds a letter addressed to him from "Peter Stevens" inviting him to join Peter in Mexico . With the letter is $1,000 in cash . The story ends with Red violating his parole to follow Andy to Mexico . </P>
