I called Ida Ruth again and was relieved to discover she was out at lunch. I left a message, indicating I'd been delayed by a meeting with a client. Don't ask why I fib to a woman who doesn't even cut my paycheck. Sometimes I lie just to keep my skills up. I staggered out of bed and into the bathroom, where I brushed my teeth. I felt as if I'd been anesthetized, and I was sure that none of my extremities would function. I propped myself against the wall in the shower, hoping the hydrotherapy would mend my skewed circuits. Once dressed, I found myself eating breakfast at one in the afternoon, wondering if I'd ever get myself back on track again. I put on a pot of coffee and dosed myself with caffeine while I made some phone calls to San Francisco.

I didn't get very far. Instead of Joseph Ayers, I got an answering machine that may or may not have been his. It was one of those carefully worded messages that bypasses confirmation of the party's name or the number called. A mechanical male voice said, "Sorry I wasn't here to take your call, but if you'll leave your name, number, and a brief message, I'll get back to you."

I left my name and office number and then left messages on answering machines for both R. Turpins. One voice was female, the other male. To both Turpins I chattered happily, "I'm not sure if this is the right Turpin or not. I'm looking for Russell. I'm a friend of Lorna Kepler's. She suggested I call if I was ever in San Francisco, and since I'm going to be up there in the next couple of days, I thought I'd say hi. Give me a call when you get this message. I'd love to meet you. She spoke so highly of you. Thanks." Through San Francisco information, I checked out the names of other members of the crew, working my way patiently down the list. Most were disconnects.

As long as I was home, I opened my desk drawer and pulled out a fresh pack of index cards, transcribing the information I'd picked up on the case to date-about four cards' worth. Over the last several years I've developed the habit of using index cards to record the facts uncovered in the course of an investigation. I pin the cards on the bulletin board that hangs above my desk, and in idle moments I arrange and rearrange the data according to no known plan. At some point I realized how different a detail can look when it's seen out of context. Like the pieces in a jigsaw puzzle, the shape of reality seems to shift according to circumstance. What seems strange or unusual can make perfect sense when it's placed in the proper setting. By the same token, what seems unremarkable can suddenly yield up precious secrets when placed against a different backdrop. The system, I confess, usually nets me absolutely nothing, but a payoff comes along just often enough to warrant continuing. Besides, it's restful, it keeps me organized, and it's a visual reminder of the job at hand.

I pinned Lorna's photograph on the board beside the cards. She looked back at me levelly with calm, hazel eyes and that enigmatic smile. Her dark hair was pulled smoothly away from her face. Slim and elegant, she leaned against the wall with her hands in her pockets. I studied her as if she might reveal what she had learned in the last minutes of her life. With the silence of a cat, she returned my gaze. Time to get in touch with Lorna's day self, I thought.

I drove along the two-lane asphalt road, past the low, rolling fields of dry grass, drab green overlaid with gold. Here and there, the live oaks appeared in dark green clumps. The day was darkly overcast, the sky a strange blend of charcoal and sulfur yellow clouds. The swell of mountains in the distance were a hazy blue, sandstone escarpments visible across the face. This section of Santa Teresa County is basically desert, the soil better suited for chaparral and sage scrub than productive crops. The early settlers in the area planted all the trees. The once sear land has now been softened and civilized, but there is still the aura of harsh sunlight on newly cultivated ground. Take away the irrigation systems, the drip hoses, and the sprinklers, and the vegetation would revert to its natural state- ceanothus, coyote brush, manzanita, and rolling grasses that in dry years yield a harvest of flames. If current predictions were correct and we were entering another drought, all the foliage would turn to tinder and the land would be cleared beneath a plow of fire.

Up ahead, on the left, was the Santa Teresa Water Treatment Plant, erected in the 1960s: red tile roof, three white stucco arches, and a few small trees. Beyond the low lines of the building, I caught sight of the maze of railings that surrounded concrete basins. To my right, a sign indicated the presence of the Largo reservoir, though the body of water wasn't visible from the road.

I parked out in front and went up the concrete stairs and through the double glass doors. The reception desk sat to the left of the front entrance, which opened into a big room that apparently doubled as class space. The clerk at the desk must have been Lorna's replacement. She looked young and capable, without a hint of Lorna's beauty. The brass plate on her desk indicated that her name was Melinda Ortiz.
