Montag concedes that Mildred is a lost cause and he will need help to understand the books. He remembers an old man named Faber, an English professor before books were banned, whom he once met in a park. Montag makes a subway trip to Faber's home along with a rare copy of the Bible, the book he stole at the woman's house. Once there, Montag forces the scared and reluctant Faber into helping him by methodically ripping pages from the Bible. Faber concedes and gives Montag a homemade ear-piece communicator so he can offer constant guidance.
