He said, "Look Guys, there's a crime that needs to be solved and there's a clue in one of the public libraries in Brooklyn. The clue is stuck inside a book, between pages 165 and 166.

Two of the guys jumped up and bolted out the door. The third guy just sat there. The private detective said to the man who remained, "You got the job." Why did he get the job? What did he know that the other two candidates didn't know?
