I think the only Konigsberg I read was The Mixed Up Files of Mrs Basil E. Frankweiler, which I loved because I too have a mania for filing things (hence my RL job, of course). Looking forward to CMBYN and WG -- there's nothing like swapping books, I'm convinced that my mom and I are solely responsible for the survival of the USPS due to the large boxes of same that shoot back and forth across the country.
