Since Montag met Clarisse, his brief conversation with Faber in the park had been popping into his head more often. After he spends the day with Mildred reading, "again he found himself thinking of the green park a year ago" where he had sat next to Faber on the park bench, and been quite sure that Faber had quoted what Montag sensed "was a rhymeless poem." Since his world had been turned upside down with Clarisse, and his ever-increasing dissatisfaction, Montag turned to Faber to take the next step. So, while Faber was on his mind, he gives him a ring, and asks how many Bibles are still left, "how many copies of Shakespeare and Pluto?" His question is sincere, but of course it scares Faber, who thinks it's a trick, some way to trap him, and hangs up. So, Montag goes to visit him, and it goes from there.
