As Montag read his book, a faint sound of sniffing, in which it sounded like the mechanical hound, came from the door. This put Mildred in a panic that led her to beg Montag to stop reading and to focus on something else.
When Montag wanted to learn more about the books he had, it occurred to him that he once met someone in the past that could help. He recalls a time where long ago, he met a man named Faber who showed him a book of poetry. However, during this time, Montag was too scared to go any further into the conversation with the old man.
This invigorated Montag to call up Faber in hopes of scheduling a meeting with him regarding the books. He dials his number and when a shaky old voice answered, Montag immediately bombarded him with questions regarding books. This caused fear out of Faber resulting in him hanging up.
At this point in time, Montag felt numb. He didn't know what to think anymore of his situation, all he knew was that he needed to go to Faber's house and get answers quick. So that's exactly what he did.
Arriving at Faber's house, Montag pleaded for his assistance in finding the true history and meaning behind books. After a short confrontation, Faber agreed to help. He gave Montag a green bullet which would allow them to communicate from long distances. They also came up with a plan in which they would find someone with a printer.
After hopping onto the subway to make his way home, he was reading the Bible as a subway speaker repeated an ad that would later bury into Montag's mind of how much he heard it during that subway trip home.
