Some well-known novel that I just can't remember the title of. I am now becoming convinced that it was mentioned as a favorite book of one of the characters in Where in Time is Carmen Sandiego (you identified the criminal by gathering clues on them), and I have actually gone to the trouble of downloading an emulator in the hopes of figuring it out. LAME.

But now I'm going to go do a couple of productive things and tend to my sick husband.
