The backs of his thighs were bulging, his hamstrings taut as guy wires. Sweat poured off his face. Without even thinking about it, I counted reps with him. Six, seven, eight. "I hate that machine," I remarked. He smiled. "Hurts like a son of a bitch, doesn't it?" "How'd it happen?"

"I was driving up the pass with a buddy of mine late at night. Some car came up and started ramming us from behind. When we got to the bridge just over the crest of the hill, I lost it and we went off. Rick was killed. He bailed out and the car rolled over on him. I should have been killed too. Longest ten seconds of my life, you know?"

"I bet." The bridge he'd soared off spanned a rocky, scrub-choked canyon, four hundred feet deep, a favorite jumping-off spot for suicide attempts. Actually, I'd never heard of anyone surviving that drop. "You're doing great," I said. "You've been working your butt off."

"What else can I do? Just after the accident, they told me I'd never walk. Said I'd never do anything." "Who said?"

"Family doctor. Some old hack. My mom fired him on the spot and called in an orthopedic specialist. He brought me back. I was out at Rehab for eight months and now I'm doing this. What happened to you?"

"Some asshole shot me in the arm."

Bobby laughed. It was a wonderful snuffling sound. He finished the last rep and propped himself up on his elbows.

He said, "I got four machines to go and then let's bug out. By the way, I'm Bobby Callahan."

"Kinsey Millhone."

He held his hand out and we shook, sealing an unspoken bargain. I knew even then I'd work for him whatever the circumstances.

We ate lunch in a health-food cafe, one of those places specializing in cunning imitation meat patties that never fool anyone. I don't understand the point myself! It seems to me a vegetarian would be just as repelled by something that looked like minced cow parts. Bobby ordered a bean-and-cheese burrito the size of a rolled-up gym towel, smothered in guacamole and sour cream. I opted for stir-fried veggies and brown rice with a glass of white wine of some indeterminate jug sort.

Eating, for Bobby, was the same laborious process as working out, but his single-minded attention to the task allowed me to study him at close range. His hair was sun-bleached and coarse, his eyes brown with the kind of lashes most women have to buy in a box. The left half of his face was inanimate, but he had a strong chin, accentuated by a scar like a rising moon. My guess was that his teeth had been driven through his lower lip at some point during the punishing descent into that ravine. How he'd lived through it all was anybody's guess.

He glanced up. He knew I'd been staring, but he didn't object.

"You're lucky to be alive," I said.

"I'll tell you the worst of it. Big hunks of my brain are gone, you know?" The drag in his speech was back, as though the very subject affected his voice. "I was in a coma for two weeks, and when I came out, I didn't know what the fuck was going on. I still don't. But I can remember how I used to be and that's what hurts. I was smart, Kinsey. I knew a lot. I could concentrate and I used to have ideas. My mind would make these magic little leaps. You know what I mean?"

I nodded. I knew about minds making magic little leaps.

He went on. "Now I got gaps and spaces. Holes. I've lost big pieces of my past. They don't exist anymore." He paused to dab impatiently at his chin, then shot a bitter glance at the handkerchief. "Jesus, bad enough that I drool. If I'd always been like this, I wouldn't know the difference and it wouldn't bug me so much. I'd assume everybody had a brain that felt like mine. But I was quick once. I know that. I was an A student, on my way to medical school. Now all I do is work out. I'm just trying to regain enough coordination so I can go to the fuckin' toilet by myself. When I'm not in the gym, I see this shrink named Kleinert and try to come to terms with the rest of it."

There were sudden tears in his eyes and he paused, fighting for control. He took a deep breath and shook his head abruptly. When he spoke again, his voice was full of self-loathing.

"So. That's how I spent my summer vacation. How about you?"

"You're convinced it was a murder attempt? Why couldn't it have been some prankster or a drunk?"

He thought for a moment. "I knew the car. At least I think I did. Obviously, I don't anymore, but it seems like… at the time, I recognized the vehicle."

"But not the driver?"

He shook his head. "Couldn't tell you now. Maybe I knew then, maybe not."
