While I was on the phone with Bysen, Morrell had made me a cappuccino and a pita with hummus and olives. I sat at his desk, eating, while I talked to Bysen’s wife. In a quiet, almost little-girl voice, Annie Lisa Bysen told me nothing: oh, yes, Billy had friends, they were all in the church youth group together, they sometimes went camping together, but never without him talking to her first. No, he didn’t have a girlfriend; she repeated his participation in True Love Waits, and how proud they were of Billy after their experience with their daughter. No, she didn’t know why he hadn’t come home, he hadn’t talked to her, but “my husband” was sure he was with that preacher in South Chicago. They had asked their own pastor, Pastor Larch-mont, to call down to the South Side church, but Larch-mont hadn’t been able to reach anyone yet.

“It was probably a mistake, that exchange program with the inner-city churches, they have so many bad kids who can influence Billy. He’s so impressionable, so idealistic, but Daddy Bysen wanted Billy to go work in the warehouse. It was where he started his business, and all the men in the family have to go. I tried to tell William we should just let Billy go to college, like he wanted, but you might as well talk to Niagara Falls as get Daddy Bysen to change his mind, so William didn’t even try, just sent Billy down there, and ever since it’s been Pastor Andrés, Pastor Andrés, as if Billy was quoting the Bible itself.”

“What about your daughter, Billy’s sister-does she know where he is?”

A long pause at the other end. “Candace-Candace is in Korea. Even if it wasn’t so hard to get to her, Billy wouldn’t do that; he knows how much William-how much we-would hate it.”

I wished I did have time to drive up to South Barrington to the Bysen enclave. There’s so much that you get from body language that you can’t see over the phone. Did she really believe her son would avoid his sister on his parents’ say-so-especially if he was running away from home? Did Annie Lisa do everything Daddy Bysen said? Or did she resist passively?

I tried to get Candace’s e-mail address, or a phone number, but Annie Lisa refused even to acknowledge the question. “What about your sister-in-law, Jacqui Bysen. Did Billy talk to her at the warehouse yesterday?”

“Jacqui?” Annie Lisa repeated the name doubtfully, as if it were in a strange language, maybe Albanian, that she’d never heard of. “I guess it never occurred to me to ask her.”

“I’ll do that, Ms. Bysen.” I took the names of the two youths she thought her son might be closest to, but I expected the Bysens were right: Papa and Mama Bear had insulted a man Billy looked up to, and Baby Bear had probably fled to him for cover. If he hadn’t, I suppose I could begin the unenviable job of trying to find Candace Bysen. I would also check area hospitals, because you never know-accidents happen even to the children of America ’s richest men. I scribbled all this down in a set of notes, since I’ve learned the hard way that I can’t keep track of so many details in my head.

I had business in the Loop for a couple of significant clients, but I finished before one and drove early to the South Side. I stopped by the warehouse to talk to Patrick Grobian first. He and Aunt Jacqui were deep in a discussion of linens; neither had seen Billy today.

“If he wasn’t a Bysen, he’d be out on his can, believe me,” Grobian snapped. “No one who wants a job with By-Smart comes and goes as they please.”

Aunt Jacqui stretched, catlike, with the same look of mischief around her mouth I’d seen yesterday during the uproar at the prayer meeting. “Billy is a saint. You’ll probably find him eating honey and locusts in a cave someplace, maybe even under the boxes in the basement-he’s always preaching to Pat and me about work conditions here.”

“Why?” I widened my eyes, innocence personified. “Is there something wrong with work conditions here?”

“It’s a warehouse,” Grobian said, “not a convent. Billy can’t tell the difference. Our work conditions comply with every OSHA standard ever written.”

I let that lay. “Would he go to his sister, do you think?”

“To Candace?” Jacqui’s carefully waxed brows rose to her hairline. “No one would go to Candace for anything except a trick or a nickel bag.”

I left while she and Grobian enjoyed a complicit laugh over that witticism. I had to be at the school for basketball practice at three, which is when Rose’s shift also ended. I couldn’t keep the girls waiting for me, so that meant if I wanted to talk to Rose I had to go back to the factory.

The yard in the middle of the afternoon looked different than at six in the morning. A half-dozen cars were parked on the weedy verge, a panel truck stood in the drive, partly blocking my way, while several men were hauling fabric, shouting to each other in Spanish. I drove the Mustang onto the weeds, next to a late-model Saturn.

The factory’s front doors stood open, but I went down to the loading bay, where a second truck was docked, motor running. I went over next to it and pulled myself up onto the lip of the dock, hoping to avoid both the foreman and Zamar. I sketched a grin and a wave at the men, who had stopped to stare at me. They had driven a forklift up to the back of the truck and were loading boxes, which they hurriedly covered with a tarp when they saw me watching. I pursed my lips, wondering what they were hiding. Maybe they were even smuggling some kind of contraband. Maybe this somehow lay behind the sabotage attempts, but they were staring at me with so much hostility that I went on in to the main part of the factory.

On one side of the floor, a team of women were folding banners into packing crates. As luck had it, Larry Ballatra, the foreman, was right in front of me, barking orders to the crew. I passed him without pausing, going straight to the iron stairs. He glanced at me but didn’t seem to really notice me, and I ran up to the work floor.

Rose was at her station, working this time on an American flag, outsize, like the one hanging over the shop floor. The soft fabric was falling from her machine into a wooden box: the U.S. flag must not touch the ground. I squatted next to her so that she could see my face.

She gasped and turned pale. “You, what are you doing here?”

“I’m worried, Rose. Worried about you, and about Josie. She said you had to take a second job, and you left her in charge of the boys and the baby.”

“Someone has to help out. You think Julia can do it? She won’t.”

“You said you want Josie to go to college. It’s too much responsibility for her, at fifteen, and, besides, it makes it hard for her to study.”

Her lips tightened in anger. “You think you mean well, but you know nothing about life down here. And don’t tell me a story about growing up here, because you still know nothing, anyway.”

“Maybe not, Rose, but I know something about what it takes to leave here to go to college. If you can’t be with Josie, making sure she gets her homework done, what’s she going to do? If she gets frustrated with the responsibility, she could start cruising the streets, she could come home with another baby for you to look after. What job is important enough for that?”

Anger and anguish chased each other across her face. “You think I don’t know that? You think I don’t have a mother’s heart? I have to take this other job. I have to. And if Mr. Zamar, if he sees you here, he will fire me anyway from this job, then I have nothing for my children, so leave before you destroy my whole life.”

“Rose, what changed overnight? Monday, you needed me to find the plant saboteurs; today, you’re scared of me.”

Her face was contracted in torment, but her hands kept steadily feeding fabric through the machine. “Go, now! Or I will yell for help.”
