Montag is a hero because he stole a book, risked his life to read books to women, and fled his own existence in order to safeguard books. Montag began his career as a regular firefighter until Clarisse asked him whether he was pleased one day. Mildred, his wife, inquires as to why he became a firefighter. He replies that it's an honest job and that he likes saving people. They have a son named Bobby who believes his father is alive even though Montag has not returned home since he left them. When Bobby turns eighteen, he decides to search for his father. During his quest, he meets Lisbeth Salander, a computer hacker who may be able to help him find out what happened to his father. Bobby gets involved with some shady characters who may or may not be trustworthy, so he needs someone reliable who can protect him. Since Montag is still alive and well, he becomes Bobby's guardian angel. After rescuing Lisbeth from some muggers, Montag realizes that she is more than just a beautiful woman but also a brilliant hacker who knows her way around computers. So he asks her to help him find his father's fire station so they can start looking for evidence that would identify the villains. While searching through old photographs, they discover that the chief of the fire department at the time of Montag's arrival in Stockholm is none other than... Dr. Frankenstein!
