The door opened as I approached it, and I stepped into an elegant entryway of dark wood, with rich burgundy carpeting. Another black-uniformed sec-guard stood just inside the door, again standing at perfect attention. Two medieval suits of armor flanked the hallway. No sooner had I passed between them, followed by my huge escorts, than a loud electronic beep sounded behind us. When I spun to look, red lights were glowing behind the visors of both suits of armor. The sec-guard at the door hurriedly hit a button, killing the lights and stilling the electronic tone. For a moment I wondered what was going down, then realized the beep had sounded just as my minders had walked between the suits of armor.
