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."

The house was surrounded by a narrow band of yard, generous by San Francisco standards, where houses were usually constructed smack up against each other. A high boxwood hedge had been planted just inside the wrought-iron fence to maximize privacy. I moved up the brick walk. The grass on cither side was tender green and recently mowed. The house was a looming three stories of old red brick, aged to the color of ripe watermelon. All of the leaded-glass windows were framed in pale gray stone. The mansard roof was gray slate, and the entire facade was washed with indirect lighting. From the rear, I could hear the alcohol-amplified voices of numerous guests superimposed on the harmonies of a three-piece combo. Occasionally a burst of laughter shot upward like a bottle rocket, exploding softly against the quiet darkness of the neighborhood.

I rang the bell as instructed. A maid in a black uniform opened the door and stepped back to admit me. I gave her my name and told her Mr. Ayers was expecting me. She didn't seem to care one way or the other, and the black all-purpose dress apparently suited her just fine, thanks. She nodded and departed, allowing me a moment to take in my surroundings. The foyer was circular, with a black marble staircase curving up from the right. The ceiling rose a full two stories and was capped with a cascading chandelier of gilt and flashing prisms. One of these days an earthquake would send the weight of it crashing, and the maid would be flattened like a cartoon coyote.

Yet another man in a tuxedo appeared in due course and escorted me toward the back of the house. The floors were black-and-white marble squares, laid out like a gameboard. The ceilings in the rooms we passed were a good twelve feet high, rimmed with plaster garlands and strange imps peering down at us. The walls in the hallway were covered in dark red silk, padded to dampen sound. I was so intent on my survey, I nearly bumped into a door. The butler butled on, ignoring me discreetly when I yelped in surprise.

He ushered me into the library and pulled the double doors together as he left the room. A large Oriental rug spread a soft mauve pattern across the parquet floor. On the left, the room was anchored by a massive antique desk of mahogany and teak, inlaid with brass. The furniture-an oversize sofa and three solidly constructed armchairs-was upholstered in burgundy leather. The room was functional, fully used, not some tidy assemblage designed to impress. I could see file cabinets, a computer setup, a fax machine, a copier, and a four-line telephone. Mahogany shelves on three walls were lined with books, one section devoted to film scripts with titles inked across the visible end.

On the fourth wall, floor-to-ceiling windows overlooked the walled grounds in the rear, where the party was in full swing. The noise level had risen, but the brunt of it was muted by the mullioned panes. I stood at the windows and looked down at the crowd below. Sections of the immense garden had been tented for the occasion, the red canvas glowing with candlelight. Tall propane heaters had been placed along the perimeter to warm the chilly night air. Tiny bulbs had been strung through all the saplings on the property. Every branch was defined by pinpoints of illumination. Tables had been covered in red satin cloths. The centerpieces were arrangements of dark red roses and carnations. Folding chairs were swaddled in clouds of red netting. I could see the caterers were still setting up a cold midnight supper-blood sausage, no doubt.

The invitations must have specified the dress requirements. The men wore black tuxedos, and all the women wore full- or cocktail-length dresses in red or black. The women were slim, and their hair was ornamental, dyed that strange California blond affected by women over fifty. Their faces seemed perfect, though by dint of surgery they all appeared to be much the same age. I suspected that none of these people were the cream of San Francisco society. These folk were the rich milk who had risen as close to the top of the bottle as money and ambition permitted in the course of one generation. My guess was that even as they drank, eyeing the buffet tables, they were trashing the host and hostess.
