Montag and Faber are characters in the book "Fahrenheit 451" and they devise a plan that involves planting books in the homes of firemen to help to discredit them and destroy censorship. The two have a radio earpiece that they call the "green bullet" and use so that they can talk to one another while Montag plants the books.
Faber is in charge of printing and reproducing the books. "Fahrenheit 451" is a book by Ray Bradbury that looks into a future world where people are not allowed to read books. Bradbury was a science fiction and fantasy writer who won multiple awards for his writing.
Although Bradbury's "Fahrenheit 451" is widely taught in schools, he claimed that it is not widely understood. Bradbury said that he did not write the book to be a story about government censorship nor did he write it as a response to Senator Joseph McCarthy. His book, he said, was created because he feared that television would kill books. He saw that people were starting to lose their attention spans and gravitating toward radio, short stories and, finally, television. He also says that the problem and the culprit in "Fahrenheit 451" is the people of the city and not the government in the city.
