[A 'Missing Link' essay]
Based on the interview process for Flynn Carsen, and the reaction from one of the rejected applicants, it looks as though the quest for the position of Librarian at the Metropolitan Public Library was a soul-crushing experience.
Judson was one of the Librarian Elders, and even he had to go through the rigors of facing an interview with a harridan of similar venom as Charlene.
Judson had a contemporary who was probably one of the finalists for the position. But unfortunately for him, the deciding factor in choosing a new Librarian was that pure knowledge was not the be-all and end-all.
As Judson knew, what truly mattered in Life couldn't be learned; it had to be felt. It wasn't enough just to memorize all of the knowledge in the world; it also had to be applied practically.
But for this other applicant, he had a major failing: He could not create, only copy; he could interpret the things he had learned as well as a photocopy machine.
For such an intelligent person doomed to be nothing more than a receptacle for facts without the spark to bring them to practical use, it's possible the rejection of the prestigious position of Librarian might have left him unhinged.
Perhaps he might have turned to a life of crime in retaliation, calling upon his bibliographic expertise for his modus operandi......
And so would be born.... The Bookworm!
And to prove that he could do nothing original, the Bookworm was practically interchangeable with the Riddler. He left clues to his plans in the hopes that he might lure the "Batnuisance" into a trap.
But at least the Bookworm took his crime spree to Gotham City, rather than risk the chance he might face Judson, that lethal Librarian and former kick-ass Marine.
