It was nearly midnight by now, and I could feel energy seeping out through my pores. Since I'd given up my day life to conduct my business by night, I'd noticed it was getting harder to predict the plunges into exhaustion. I longed to fling myself backward on the bed and fall asleep in my clothes. I roused myself before the notion became too seductive. In the bathroom, a printed notice warned of lingering drought conditions and begged motel guests to use as little water as possible. I took a quick (guilt-ridden) shower, then dried myself on a towel as rough as a sidewalk. I set my duffel on the bed and pulled out clean underwear and panty hose. Then I hauled out the wonder garment, my black all-purpose dress. Not that long ago, this article had been a-fester with ditch water, smelling of mildew and assorted swamp creatures. I'd sent it to the cleaners several times in the intervening months, and by now it was as good as new . . . unless you sniffed really, really closely. The fabric represented the apex of recent scientific achievement: lightweight, wrinkle-defying, quick-drying, and indestructible. Several of my acquaintances rued this latter quality, begging me to dump the dress and add another to my wardrobe. I couldn't see the point. With its long sleeves and tucked front, the all-purpose dress was perfect (well, adequate) for all occasions. I'd worn it to weddings, funerals, cocktail parties, and court appearances. I gave it a shake and undid the zipper, managing to step into the dress and my black flats simultaneously. No one would mistake me for a fashion plate, but at least I could pass myself off as a grown-up.

According to the map and the address I'd been given, Joseph Ayers was living in Pacific Heights. I laid the map on the car seat and left on the interior light so I could see where I was going. I took a left on Divisadero and headed toward Sacramento Street. Once in the vicinity, I cruised the area. Even at this hour, the Ayers residence wasn't hard to spot. The house was ablaze with lights, and a steady stream of guests, both arriving and departing, were taking advantage of the "varlet" parking out in front. I turned my car over to one of the young men in black dress pants and white tuxedo shirts. There was a Mercedes ahead of me and a Jaguar pulling up behind.

The front gate was open, and late arrivals were being steered around the side of the house toward the garden in back. Entrance to the party was being monitored by a man in a tuxedo, who viewed my outfit with visible concern. "Good evening. May I see your invitation?"

"I'm not here for the party. I have a personal appointment with Mr. Ayers."

His look said this seemed doubtful; however, he was being paid to smile, and he gave me the minimum wage's worth. "Ring the front doorbell. One of the maids will let you in."
