This chapter's epigraph comes from a famous poem by Henry Wadsworth Longfellow, who was one of the most famous poets of the twentieth century. Longfellow's poem is about a man who escapes from a prison and finds himself in the middle of a battle. He escapes from the prison by running through a maze of tunnels. He finds his way to the top of the tunnel, where he finds himself on the other side of a wall, surrounded by a wall of thick stone. The wall is made of marble, and the walls of the tunnels are made of wood. The two men escape through the tunnels.
