“Do you have another one that you can use?”

“Me?” she said.

“I have a full caseload right now,” I explained. “You, though, are free to look for Ellie full-time. You should keep looking.”

“I thought…” Ainsley looked a little disillusioned.

“I’m going to do everything I can,” I reassured her. “But you’re Ellie’s best advocate right now. Show her picture to everyone. Motel clerks, homeless people, the priests and ministers who run homeless shelters… anyone you think might have seen Ellie. Make color photocopies with a description and hang them up anywhere people will let you. Make this your full-time job.”

Ainsley Carter had understood me; she’d left to do what I’d said. But I found Ellie instead, and it was just dumb luck.

At midmorning the day after Ainsley’s visit, I’d driven out to a hotel in the outer suburbs. A clerk there had thought she’d seen a man and boy sought in a parental abduction, and I’d been asked to look into it.

I handled all kinds of crimes-all sheriff’s detectives did-but missing persons was a kind of subspecialty of my partner’s, and along the way, it had become mine, too.

The father and son in question were just packing up their old Ford van as I got there. The boy was about two years older and three inches taller than the one I was looking for. I was curious about why the boy wasn’t in school, but they explained they were driving back from a family funeral. I wished them safe driving and went back to the registration desk to thank the clerk for her civic-mindedness.

On the drive back, just before I got to the river, I saw a squad car pulled over between the road and the railroad tracks.

A uniformed officer stood by the car, looking south, almost as if she were guarding the tracks. Just beyond her, those tracks turned into a trestle across the river, and I saw the broad-shouldered form of another officer walking out onto it. It was a scene just odd enough to make me pull over.

“What’s going on?” I asked the patrolwoman when she approached my car. Sensing she was about to tell me to move along, I took my shield out of my jacket and flipped the holder open.

Her face relaxed a little from its hard-set position, but she didn’t take off or even push down her mirrored shades, so that I saw my own face in them, distended as if by a fish-eye lens. I read her nameplate: OFFICER MOORE.

“I thought you looked familiar,” Moore said. Then, in answer to my question, she said succinctly, “Jumper.”

“Where?” I said. I saw Moore’s partner, now standing out on the train tracks mid-bridge, but no one else.

“She climbed down on the framework,” Moore said. “You can kind of see her from here. Just a kid, really.”

I craned my neck and did see a slender form on the webwork of the bridge, and then the flash of sunlight on dark-gold hair.

“A girl? Like, around fourteen?”

“Yeah, she is,” Moore said.

“Where can I park?”

The trip out onto the railroad bridge kept taking me through sun and shadow, sun and shadow, not just from the bridge’s overhead structure, but also from the sun dipping behind a cloud and then back again. It was a day of broken cloud.

“I thought we radioed for the water patrol,” Moore’s partner said in greeting, mildly perplexed, as I neared him.

I knew him by sight but couldn’t quite remember his name. Something with a V. He was a few years younger than me, 25 or so. Handsome and olive-complected.

“Nobody sent for me, Officer Vignale,” I said, my memory delivering the name to me before I had to read his tag. “I was just passing by. What’s going on?”

“She’s still down there, Detective…”

“Pribek,” I said. “Sarah Pribek. Have you tried to talk to her?”

“I’m afraid to distract her. I don’t want her to lose her balance.” I turned, leaned against the railing, and looked down. Sure enough, the kid was right there, standing with her feet braced and her hands up on a diagonal strut. The mild breeze ruffled hair exactly the color and texture of Ellie Bernhardt’s.

“She’s a runaway from Thief River Falls,” I said. “At least, I’m pretty sure she is. Her older sister was downtown reporting her yesterday.”

Vignale nodded. “Water patrol is sending out a boat. Just in case we have to fish her out.”

I looked down at Ellie and the water below that.

Ellie had picked a particularly low bridge to climb out on, and that in itself was interesting. I’d never learned a whole lot about psychology, but I’d heard that when people make survivable suicide attempts, it’s often a way of asking for help. Then again, Ellie could simply have been confused, angry, and impatient and rushed out to the first structure across the Mississippi that she could find.

Either way, it was a fortunate situation. Up to a point: The river she was over was still the Mississippi.

I had grown up in New Mexico, and in the high country where I’d lived, the terrain had been crosshatched with creeks, but we’d had nothing like the Mississippi. At the age of thirteen I’d come to live in Minnesota, but even then I hadn’t lived near the river. The Mississippi had been an abstraction to me, something to be seen from a distance or crossed on the occasional road trip. It wasn’t until years later that I’d gone down to the river to check it out at close hand.

Down at the bank, a kid had been pretending to fish with plain string tied to a long branch.

“Does anyone ever go in?” I’d asked him.

“I saw a man go in once with a rope around his waist,” the kid had said. “The current took him under so fast that both his friends, they were both grown-ups, had to pull just to get him out.”

Since then I’d heard dissenting opinions on the strength and the malice of the river that divided Minneapolis. The Twin Cities’ police and emergency blotters have recorded the stories of people who have survived jumps and falls from all of its bridges. But these survivals aren’t the rule. Even sober, healthy adults who can swim and aren’t suicidal get in trouble in the river, largely due to the current. It drags you in the wrong directions: downward, where people get caught up in submerged trees and roots, and toward the river’s center, where the current flows fastest over the deepest part of the bed.

The fall from this structure might well be survivable, and the water might not be the paralyzingly frigid temperatures of midwinter. But all the same I thought it was best if things didn’t get to that point.

Holding on to a railing, I put one experimental foot out onto the edge.

“You’ve gotta be kidding me,” Vignale said.

“No kidding,” I said. “If she didn’t want someone to come talk her out of it, she would have jumped already.” I hope. “I’m worried about you, Officer Vignale,” I said. “If your partner didn’t radio ahead to keep train traffic off the bridge, I’d think about going back.”

The bridge’s framework wasn’t really any more difficult to climb down than a child’s jungle gym at the playground, but I negotiated it a lot more slowly.

“You got company, but don’t be scared,” I said when I got down to the kid’s level, keeping my voice low and modulated. Like Vignale said, I didn’t want to startle her. “I’m just coming down to talk.”

She turned to look at me and I saw that she was indeed Ellie. More than that, I saw the beauty that had so worried her older sister. Ellie had in fact changed since the taking of last year’s class picture.

She was one of those people who seriousness, even unhappiness, makes far more lovely than a smile. Her green-gray eyes were heavy-lidded, her skin clear, her lower lip very full. The freckles from the photo, fading already, were the last vestige of her child’s face. She wore a gray T-shirt and black jeans. No pastels, no ribbons, no girl stuff for Ellie. If I’d seen her from a distance, I might have taken her for a petite 21-year-old.
