I picked up the receiver, put my hand in my jeans pocket, and pulled out the card I'd been given in the limousine. The scribbled number was there, some magical combination of digits that spelled death. I dialed, giving absolutely no thought to what I was doing. I was propelled by the hot urge to act, by the blind need to strike back at the man who had dealt me this blow.

After two rings, the phone was picked up on the other end. "Yes?"

I said, "Roger Bonney killed Lorna Kepler."

I hung up. I sat down. I felt my face twist with heat, and tears spilled briefly.

I went into the bathroom and looked out the window, but the street beyond was dark. I went back to my desk. Oh, Jesus. What had I done? I picked up the phone and dialed the number again. Endless rings. No answer. I put the phone down. Hands shaking, I pulled my gun from the bottom drawer and popped in a fresh clip. I eased the gun into the waistband at the back of my jeans and pulled on my jacket. I grabbed my handbag and car keys, turned out the lights, and locked the door behind me.

I hit the 101, heading out toward Colgate. I kept checking my rearview mirror, but there was no sign of the limousine. At Little Pony Road, I took the off-ramp and turned right, continuing past the fairgrounds until I reached the intersection at State. I stopped at the traffic light, drumming my fingers on the steering wheel in impatience, checking my rearview mirror again. Along the main thoroughfare there was only one touch of color, words written out in red neon on the drugstore I spotted. SAV-ON , the sign said. The shopping mall to my left was apparently having a gala all-night sale. Klieg lights pierced the sky. White plastic flags were strung from pole to pole. At the entrance to the parking lot, a clown and two mimes were motioning for passing cars to turn in. The two mimes in whiteface began a playlet between them. I couldn't tell what silent drama the two were enacting, but one turned and looked at me as I pulled away from the light. I checked back, but all I saw was the painted sorrow on his downturned mouth.

I sped past a darkened service station, the bays and gasoline pumps shut down for the night. I could hear a burglar alarm clanging, apparently in a shop close by, but there was no sign of the police and no pedestrians running to see what was wrong. If there were actually burglars in the place, they could take their sweet time. We're all so accustomed to alarms going off that we pay no attention, assuming the switches have been tripped in error and mean nothing. Six blocks beyond, I crossed a smaller intersection heading up the road that led to the water treatment plant.

The area was largely unpopulated. I could see an occasional house on my right, but the fields across the road were scruffy and dotted with boulders. Coyotes yipped and howled in the distance, driven down from the hills by the need for water. It seemed too early in the evening for predators, but the pack was obeying a law of its own. They were hunting tonight, on the scent of prey. I pictured some hapless creature flying across the ground, in fear of its life. The coyote kills quickly, a mercy for its victim, though not much consolation.

I turned into the entrance to the treatment plant. Lights were on in the building, and there were four cars out front. I left my handbag in the car, locking it behind me. There was still no sign of the limousine. Then again, the guy wouldn't use his limo to make a hit, I thought. He'd probably send his goons, and they might well check Roger's place first, wherever that might be. A county-owned truck had been parked in the drive. As I passed, I put a hand out. The hood was still warm to the touch. I went up the stairs to the lighted entry. I could feel the reassuring bulk of the handgun in the small of my back. I pushed through the glass doors.

The receptionist's desk was empty. Once upon a time Lorna Kepler had sat there. It was curious to imagine her working here day after day, greeting visitors, answering the telephone, exchanging small talk with the control technician and senior treatment mechanics. Maybe it was her last shred of pretense, the final gesture she'd made toward being an ordinary person. On the other hand, she might have found herself genuinely interested in aeration maniforms and flash mix basins.

The interior of the building seemed quiet at first. Fluorescent lights glowed against the polished tile floors. The corridor was deserted. From one of the rear offices, I picked up the strains of a country music station. I could hear someone banging on a pipe, but the sound came from deep in the bowels of the building. I moved quickly down the hallway, glancing left into Roger's office. The lights were on, but he was nowhere to be seen. I heard footsteps approaching. A fellow in coveralls and a baseball cap came around the corner, moving in my direction. He seemed to take my presence for granted, though he took his cap off politely at the sight of me. His hair was a mass of curly gray mashed into a cap-shaped line around his head. "Can I help you with something?"
