Here I go again with one of my obsessions, the Chrysler Building. To get to my dentist's office there, you take the express elevator to the 57th floor and then walk around the corner to take the Tower Elevator to the 69th floor. But on the 57th floor, on the way to the next elevator, you will encounter what I have come to call the Mystery Office. As the possessor of an overactive imagination, I find that this office reminds me of something out of The Twilight Zone or perhaps a program on the Sci-Fi (recently renamed—wait for it—SyFy) Channel. Except for an occasionally visible young woman who appears to be a receptionist, there's never anybody in there! Is this a conference venue? Temporarily unrented space (no surprise here, with office rentals going begging in the recession)? Over several years, at whatever time I have my dentist appointment, there has never been anything taking place in this glossy, pristine space. Do covens congregate there late at night, gazing out over Manhattan from the 57th floor? Do Mafia dons occasionally plan whack jobs? Che cosa fanno li? Whatever the case may be, using this venue has got to be pricey. No one in the dentist's office seems to know anything. Have they been warned by underworld figures to keep their lips buttoned—observing omertà? Where is Mike Hammer when we need him? Or better, C. Auguste Dupin, Sherlock Holmes, or Hércule Poirot? Or, since it's a 30s Art Deco building, Philo Vance?
