I went back to the health-food restaurant where Bobby and I had eaten lunch on Monday. I was really hoping to run into him, but he was nowhere in sight. I ordered a longevity salad that was supposed to take care of 100 percent of my nutritional needs for life. What the waitress brought me was a plate piled with weeds and seeds, topped with a zesty pink dressing with specks. It didn't taste nearly as yummy as a Quarter Pounder with cheese, but I did feel virtuous, knowing I had all that chlorophyll coursing through my veins.

When I got back in my car, I checked my teeth in the rearview mirror to make sure they weren't flecked with alfalfa sprouts. I prefer not to interview people looking like I've just been grazing out in some field. I leafed through my notebook for Rick Bergen's parents' address and then I hauled out a city map. I had no idea where Turquesa Road was. I finally spotted it, a street about the size of an ingrown hair, off an equally obscure lane in the foothills that stretch across the back of town.

The house was staunch and plain, all upright lines, with a driveway so steep that I avoided it altogether and squeezed my car in along the ice plant growing below. A bald cinderblock wall prevented the hillside from tumbling into the road and gave the impression of a series of barricades as it zigzagged up to the front. Once I reached the porch, the view was spectacular, a wide-angle shot of Santa Teresa from end to end with the ocean beyond. A hang-glider hovered high up to my right, sailing in lazy circles toward the beach. The day was full of hard sunlight, meager clouds looking like white foam just beginning to evaporate. It was dead quiet. No traffic, no sense of neighbors nearby. I could see a rooftop or two but there was no feeling of people. The landscaping was sparse, composed of drought-tolerant plants: pyracantha, wisteria, and succulents.

I rang the bell – The man who came to the door was short, tense, unshaven.

"Mr. Bergen?"

"That's right."

I handed him my business card. "I'm Kinsey Millhone. Bobby Callahan hired me to look into the accident last –"

"What for?"

I made eye contact. His were small and blue, red-rimmed. His cheeks were prickly with a two-day growth of beard that made him look like a cactus. He was a man in his fifties, radiating the smell of beer and sweat. His hair was thinning and combed straight back from his face. He wore pants that looked like he'd retrieved them from a Salvation Army box and a T-shirt that read "Life's a bitch. Then you die." His arms were soft and shapeless, but his gut protruded like a basketball pumped to maximum pressure per square inch. I wanted to respond in the same rude tone he was using with me, but I curbed my tongue. This man had lost a son. Nobody said he had to be polite.
