I agreed, and re-opened my book. But for a few minutes, I read the same page over and over.

When we stopped by the motel office to ask for directions to the Ozark Valley Inn, we noticed that the older man who ran the place was not too happy about helping us. We'd learned his name was Vernon, and he wore overalls and had the worn and wrinkled face of a basset. Vernon had been pleasant enough up to now, though we hadn't seen much of him. But tonight he was distant, his gaze disapproving. "You planning on moving your bags over there?" he asked, almost hopefully.

"No," I said, surprised. "We're just meeting someone for dinner in the restaurant at the inn."

" 'Cause I been meaning to tell you, I'm going to need those rooms pretty soon. Hope you two wasn't planning on staying very long."

"I'm sure you have tons of business coming in," I agreed, maybe a little coldly. "And we won't stay a minute longer than we have to."

"Glad to hear it."

"I guess no one's going to ask us to judge the floats in the homecoming parade," I said to Tolliver when we were in the car.

He smiled, but it was a small smile. "The sooner we can get out of Sarne, the better," he said.

Mary Nell came in seven minutes after we were seated at a table in the inn, which was on the southern side of the town. Her face was flushed and her cell phone was in her hand. I was willing to bet she'd lied to her mother about where she was going and whom she was going to be with. I almost hated the girl at that moment, for the trouble she might get us into.

"Sorry I'm late," Mary Nell said, as she took a chair. "I had some things I had to do at home. My mom is so paranoid."

"She lost your brother," I said. "I'm sure that's made her more protective." I wouldn't have thought even a self-absorbed teenager could have missed that point.

The girl flushed deep red. "Of course," she said stiffly. "I just mean, she doesn't seem to know how old I am." She'd dressed with care, in new low riders with a tight green T-shirt. She wore a soft fuzzy cardigan sweater and boots.

"That's a common thing with mothers," I said. My own mother had forgotten how old I was, after she'd started chasing the drugs with alcohol. She'd decided I was much older and needed a boyfriend. She picked a doping buddy of hers who was willing to give her free samples for the privilege of being my first "date." Tolliver had gone off to college by then, and I'd had to spend a day locked in my room. I had known that eventually they'd go to sleep and I'd be able to get out of the house, but I was hungry and thirsty and had no access to a bathroom. After that, I kept bottled water and a box of crackers and an old cooking pot in my room.

"Have you lived in Sarne all your life?" Tolliver asked Mary Nell.

She flushed when he spoke directly to her. "Yes," she said. "My dad's parents were born here, too. Dad died just before Dell." I was startled. When Edwards had told me Sybil was a recent widow, I hadn't realized how recent. "Dell, he really missed Dad... . He was closer to Dad than me." She sounded vaguely resentful.

"I want to ask you a question, Mary Nell," I said. "I don't want to upset you any more than I have to, but when you were talking to us the other night, you paused after you said one sentence. You said something like, ‘I knew he wouldn't kill Teenie and...' and then you stopped. What were you going to say?"

Mary Nell eyed me. You could tell her feelings were conflicted. "Please tell us, Nell," Tolliver said, and she crumbled when she looked into his dark brown eyes. He'd called her something special.

"Okay," she said, leaning across the table to share her big secret. "Dell told me, the week before he and Teenie... the week before they died, that Teenie was gonna have a baby." Her heavily made-up eyes were as big and round as a raccoon's. The girl was clearly shocked that her brother had been having sex with his girlfriend, and she just as clearly considered the pregnancy top-secret knowledge.

"No one knew?"

"He sure didn't tell my mom. She would've killed him." Then, as she realized what she'd said, Mary Nell turned red as a brick, and tears filled her eyes.

"That's okay," I said hastily, "we know your mom wouldn't really do that."

"Well, Mom never has liked Teenie's mom too much. I don't know why. Miss Helen used to work for us a few years ago, and I thought she was great. Always singing."

And I could tell that she suddenly remembered that Helen Hopkins had been murdered, too. There was a look on her face, a lost look, like she was drowning.

"If I'd killed everyone I didn't like, I'd be able to dress in their scalps," Tolliver said.

Mary Nell gave a startled giggle and covered her mouth with her small hand.

After all this time, could an autopsy establish Teenie's pregnancy?

"Dell didn't tell anyone but you?" I asked.

"No one knew but me," Mary Nell said proudly.

Mary Nell was sure her brother hadn't told anyone about the baby, but what about Teenie? Had she told someone? Her mother, maybe?

Her mother, who was... gee, let me think... dead.

AFTER Tolliver and I had exchanged glances, we steered off the subject quickly. Mary Nell's sad, tearful face had already attracted some attention from the sparse clientele. Her coloring cleared up and her demeanor brightened as she talked about happier topics, addressing her conversation almost exclusively to my brother. Tolliver found out that Nell planned to go to the University of Arkansas the next year, that she wanted to be a physical therapist so she could help people, that she was a cheerleader and didn't like algebra. Her cheerleading sponsor was totally cool.

I was free to think my own thoughts. Mary Nell didn't seem much different from any of the girls I'd known in high school, the girls with sober parents, the girls who had enough money to ward off worry and homelessness. She was bright but not brilliant, virginal but not saintly. The loss of her sibling had left her drifting, searching for a new identity when her old one had been shaken at its core. I could see the knowledge of her brother's secret life with Teenie had disturbed Mary Nell deeply, until that shock had been smothered by the greater trauma of Dell's death. Clearly, sharing her brother's secret had relieved the knot of tension deep inside Mary Nell Teague. It didn't seem to make a difference to Mary Nell that the people she'd shared it with were strangers.

The girl was fascinated with Tolliver. Since she was popular, pretty, and a teenager, Mary Nell was sure Tolliver would find her equally fascinating. I observed Mary Nell flounder through the conversation, trying to find the key to cajoling my brother into noticing she was a woman. Mary Nell would begin an anecdote about her homeroom teacher, realize that was a kid topic, and make a huge effort to switch to some conversational gambit she believed would appeal to an older man.

"Did you go to college?" she asked Tolliver.

"I went two years," he said. "Then I worked for a while. After that, Harper and I started our traveling."

"How come you don't get a regular job and stay somewhere?" Like real people do.

Tolliver looked at me. I looked back. "Good question," he said. I looked at him askance, determined not to answer. She hadn't asked me.

"Harper helps people," he said. "She's one of a kind."

"But she gets paid for it," Nell said, outraged.

"Sure," Tolliver said. "Why not? When you get to be a therapist, you'll get paid."

Mary Nell ignored this royally.

"And she can do that by herself. Does she have to have help?"

Hey, sitting right here! Listening! I spread my hands, palms up. Only Tolliver noticed the gesture.
