I wandered back into the middle of the waiting room and took a good, hard look around. The soap-bubble doors took up much of one wall. In the center of the opposite wall was a single wooden door. (Not mahogany; something even richer-looking, with an even stronger grain pattern. A native Hawai'ian species, maybe?) Again, there was no nameplate on the door. But it didn't need one. I can recognize the office door of the head muckamuck without any outside cues.
