From that day on, Sydney Blake had a hobby. Trying to work out a good reason for visiting the thirteenth floor. Unfortunately, there just wasn’t any good reason so long as the tenants created no nuisances and paid their rent regularly.

Month in, month out, the tenants paid their rent regularly. And they created no nuisances. Window washers went up to wash windows. Painters, plasterers, and carpenters went up to decorate the offices on the thirteenth floor. Delivery boys staggered up under huge loads of stationery.
