"You know what I mean," said the Judge with some asperity. "The 
building should have a system for filtering nanosites from the air. If this 
system is working properly, and if the girl does not take the book out of her 
building, then she should go unnoticed by these." The Judge drew a streak 
through the dust on the book's cover and smeared the toner between his fingers. 
"Speak with the landlord of her
building, and let him know that his air-filtering system is due for an 
inspection, and that this is genuine, not just a solicitation for a 
bribe."
