Driving north on the 101, I kept an eye on the rear end of Daisy’s 1980 Honda, dusty white with an enormous dent across the trunk. I couldn’t think how she’d done that. It looked like a tree trunk had fallen on her car. She was the kind of driver who stayed close to the berm, her brake lights flashing off and on like winking Christmas bulbs. As I drove, the flaxen hills appeared to approach and recede, the chaparral as dense and scratchy-looking as a new wool blanket. A gray haze of dried grass undulated at the side of the road, whipped by the breeze created by the passing cars. A recent fire had created an artificial autumn, the hillsides as bronze as a sepia photograph. Tree leaves were scorched to a papery beige. Shrubs were reduced to black sticks. Tree stubs, like broken pipes, protruded from the ashen earth. Occasionally, only half a tree would be singed, looking as though brown branches had been grafted onto green.

Ahead of me, Daisy activated her turn signal and eased off the highway, taking the 135, which angled north and west. I followed. Idly I picked up the map I’d folded into thirds and laid on the passenger seat. A quick glance showed a widespread smattering of small towns, no more than dots on the landscape: Barker, Freeman, Tullis, Arnaud, Silas, and Cromwell, the latter being the largest, with a population of 6,200. I’m always curious how such communities come into existence. Time permitting, I’d make the rounds so I could see for myself.

Daisy’s house was off Donovan Road to the west of the 135. She pulled into a driveway that ran between two 1970s-era frame-and-stucco houses, mirror images of each other, though hers was painted dark green and the one next door was gray. Against her house, bougainvillea grew from thick vines that climbed as far as the asphalt shingle roof in a tangle of blossoms the shape and color of cooked shrimp. I parked at the curb and got out of my car while she pulled the Honda into the garage and removed her suitcase from the trunk. I stood on the porch and watched her unlock the door.

“Let me get some windows open,” she said as she went in.

I stepped in after her. The house had been closed up for days and the interior felt hot and dry. Daisy moved through the living and dining rooms to the kitchen, opening windows along the way. “The bathroom’s off that hall to the right.”
