"This isn't a simple licensure issue, like a doctor forgetting to send in the renewal paperwork," Prewitt corrected me. "We're not at all sure this guy is really a doctor. He's probably just pa.s.sing himself off as one. He's also possibly operating out of a public housing building somewhere."

"That's daring," I said. "Has this guy botched anything and dumped someone on the ER doorstep?"

"Not that I've heard," Prewitt said. "But we really don't know very much. It's just a subtle, persistent rumor. There may be nothing to it."

There were two ways that statement could be interpreted. It could mean, This case is probably a dead end, so I'm kicking it down to my youngest and least-experienced investigator, the one who's already under a cloud around the department. This case is probably a dead end, so I'm kicking it down to my youngest and least-experienced investigator, the one who's already under a cloud around the department. Or he could be saying, Or he could be saying, This is a tricky case with few leads, one that needs to be handled carefully. Show me your stuff, Pribek. This is a tricky case with few leads, one that needs to be handled carefully. Show me your stuff, Pribek.

"What do you want me to do?" I asked.

"Just ask around, check out the story with your informants," Prewitt told me.

"Sure," I said. "I can do that."

He left with a little tilt of his chin that said, Carry on. Carry on.

I slid open my lowest desk drawer and found an envelope toward the back. Inside it was a motley a.s.sortment of pieces of paper, the names and phone numbers of my informants. Now I shuffled through them, thinking of where to start. Prewitt hadn't said anything to suggest the unlicensed doctor was urgent. Nor had he even sounded hopeful that I was going to find anything. For that very reason, I wanted to start working on this right away. I was going to find this guy, and faster than Prewitt expected, too. I was going to show him my stuff.

Someone cleared her throat before me. "Sarah?"

It was Tyesha, one of our nonuniformed support staff, standing in front of my desk. She was five-two and still thin at 30 despite having three children. She greeted people at the front desk, answered the phone, and generally directed traffic.

"What's up?" I said.

"There's a young woman here who wants to talk about her brother being missing," Tyesha said.

"Has she filed a report?" I asked.

"She says she has, but that it's a little more complicated than that," Tyesha explained. "She'd like to talk to someone about it."

"Okay," I said. "Send her back."

Tyesha returned a moment later with a woman even shorter than she, about five-one, with a fragile, slender build. She wore what I took for office clothes, a shimmering lavender silk shirt over black trousers and low-heeled black shoes. She had long blond hair, blue eyes, milk-white skin. "This is Detective Sarah Pribek," Tyesha said. "Sarah, this is..." She stopped, in the manner of someone who's either forgotten a name or how to p.r.o.nounce it. "I'm sorry," she said to the visitor.

"Don't be," the young woman said. "It's Marlinchen."

"Nice to meet you, Marlinchen," I said. "Please, have a seat."

She did, and Tyesha left us together.

"Spell your name for me, will you?" I asked her.

The young woman reached for the yellow sticky pad on my desk and turned it around to face her. Taking a pen from her backpack, she wrote quickly, then pulled off the top sheet.

Marlinchen Hennessy, it said. She'd added her phone number underneath. it said. She'd added her phone number underneath.

"Is this a Swedish name?" I asked.

"'Marlinchen' is German," she said. "Technically, it's p.r.o.nounced Mar-leen-chen, but everyone gives it an Americanized p.r.o.nunciation: Mar-lin-chen." It had the sound of a speech she'd given many times before. "The last name, Hennessy, is Irish, of course. My brothers all have traditional Celtic names. My twin brother's name is Aidan." Her voice dropped a little lower. "He's the one I'm here about."

"Tell me about that," I said. "You said that you filed a report already?"

Marlinchen Hennessy nodded. "I reported Aidan missing in Georgia. That's where he's been living for the past five years. He-"

I held up a hand to stop her. "Wait. He lives in Georgia and that's where he's missing from, but you want Hennepin County to look into it?"

She nodded quickly. "Aidan's from here, and has connections here. He could be headed back this way, and I thought that might make it pertinent to you, here in Hennepin County."

I frowned. "'Headed back this way'? In other words, you think he's traveling of his own volition?"

"That's what they think down in Georgia," Marlinchen said.

"If that's true," I said, "then there's nothing to investigate. Adults are free to move about without checking in with relatives."

"Aidan's not 18 yet," she said quietly.

"But you said he's your twin," I said.

"I'm 17," she said.

I hoped my surprise didn't show on my face. I'd taken her for 20, 21. "Okay," I said, thinking, "this raises another issue entirely. What are your parents doing about all this?"

"My mother is dead," Marlinchen told me.

"I'm sorry," I said. Then, just as she was about to speak again, I asked, "How long ago?"

"Ten years," she said.

"I'm sorry," I said, then realized I'd just said that a moment earlier.

Marlinchen Hennessy moved on. "My father is Hugh Hennessy, the writer." She looked for recognition in my face. "He wrote The Channel The Channel?" she prompted.

"That sounds familiar," I said, "but we're getting off the point. Where is your father today?"

"Why do you ask?" she said.

"What I'm wondering is why he's sent his 17-year-old daughter to deal with the Sheriff's Department instead of coming himself," I explained.

"He doesn't know about Aidan," Marlinchen said quickly. "He's up north, in a cabin he owns near Tait Lake. It's kind of remote, and it doesn't have a phone."

Her eyes had an odd glitter to them. It looked like alarm, but I didn't understand its source.

"Dad goes there to write," she said. "When his work isn't going well, he needs lots of quiet and solitude. But he didn't start going up there until I was old enough to take care of my three younger brothers. He's very responsible."

She'd veered off into a defense of her father's parenting methods, for no reason I could ascertain. I tried to bring her back on course.

"But there's someone who can go get him, right?" I said. "A neighbor, a ranger, somebody like that? I'm just saying that this is something Aidan's father should know about."

That remark didn't quite have the calming effect I'd planned.

"I don't understand why there's this emphasis on my father!" Marlinchen said, her voice rising. "He's not a policeman. He's He's not going to find Aidan. That's the job of the police, and they're not doing anything as far as I can tell!" not going to find Aidan. That's the job of the police, and they're not doing anything as far as I can tell!"

I tapped the end of a pencil against my desk. "If this is the quality of cooperation you're giving the police in Georgia," I said, "it's hard for me to imagine what they could could do for you." do for you."

"I shouldn't have come," Marlinchen said quickly, jumping to her feet.

"Wait," I said placatingly, but she was already nearly running for the exit. Everyone working around me stopped to watch her flight.

"Wait," I said more loudly, standing. But she was gone. I said more loudly, standing. But she was gone.

"She's fleeing the interview! She's fleeing the interview!" a deputy said, mimicking Frances McDormand's broad Minnesotan accent in Fargo. Fargo. The other deputies laughed. The other deputies laughed.

"Thanks," I said. "If you enjoyed the show, my monkey will be around shortly with a tin cup."

With no way to follow up on that resounding success, I drove to South Minneapolis to talk to my first informant about Prewitt's medical-fraud case. to follow up on that resounding success, I drove to South Minneapolis to talk to my first informant about Prewitt's medical-fraud case.

When Shiloh had gotten accepted to the FBI Academy and quit the MPD, he'd had a kind of fire sale, giving me some useful phone numbers, from his contacts with federal agencies to street-level informants. Like Lydia Neely, who he knew from his early career in Narcotics. Lydia had been arrested while driving over the county line with a lot of British Columbian marijuana in the trunk of her car. Several officers had been in on the bust, as is typical of Narcotics cases, but it was Shiloh who'd taken an interest in Lydia's situation. He was the one who'd found out that she had no priors and was muling for a boyfriend who subscribed to the theory that women are less likely to be stopped by drug agents. Had someone not informed on Lydia, the boyfriend would have been right.

Shiloh, with his typical concern for the unfortunate, had gone out of his way to intercede for Lydia and to keep her out of prison. She'd done some time in the workhouse, and checked in with a probation officer afterward. She'd also become Shiloh's informant, and when he left the MPD, I'd inherited her name and number.

I hadn't seen Lydia in some time, mostly because she wasn't the most useful informant anymore. She'd gotten a good job in a South Minneapolis salon, and the new and better boyfriend she'd found had recently become a husband. That sort of rehabilitation was the point of the intervention Shiloh had made, but it also meant that she didn't a.s.sociate with criminals much anymore, and so she didn't get to hear interesting things. It's a truth the public doesn't want to hear: good citizens often don't make for good informants, and good informants are necessary to police work.

But I had to start somewhere in my search for Prewitt's unlicensed doctor, and Lydia still lived close to the ground.

Her job made it particularly convenient for me to stop by. For obvious reasons, I didn't identify myself as a cop when visiting informants. It was useful, for that reason, to be a female investigator visiting a women's salon; it raised no antennae among bystanders. More good fortune: she was working in a narrow back room of shampooing stations when I arrived, with no one close enough to overhear us.

"Hey, Detective Pribek," Lydia said. Hard plastic clattered as she rinsed a set of curlers with a jet of water from the hose, her brown hands moving in the sink.

"Sarah," I corrected her.

"You want a cup of coffee?" she asked me.

"No, thanks," I said. Her courtesy made me uncomfortable, because I didn't feel I'd built any personal rapport with her; rather, I sensed she tolerated me because she'd liked Shiloh. "I'm not going to take up too much of your time," I went on. "I just need to know if you've heard about something."

When I explained my errand, something flickered in Lydia's eyes.

"You know who I'm talking about?" I prompted.

"Not by name," Lydia said. "You hear him whispered about, but that's all."

"So what's his story?" I asked. "Is he even a doctor, or is he an unemployed vet, or what?"

Lydia shook her head. "Sorry, I don't know any of those things." Then she added, "I think Ghislaine knows him."

"Oh," I said. "I didn't know you knew her."

Ghislaine Morris had been another of Shiloh's informants. He had given me her number, too, but I hadn't had much opportunity to deal with her.

"She was my roommate," Lydia said. "Before the bust." She meant her own arrest for transporting.

"All right," I said. "I'll talk to Ghislaine."

Lydia slid a clear plastic bin of rollers into a cabinet above the line of shampoo bowls and closed the door. I moved into the doorway but didn't leave.

"How's married life?" I asked.

"Good," Lydia said.

"You like it?" I added lamely. She just said as much, stupid, She just said as much, stupid, I told myself. I told myself.

"Yeah," she said.

"Well, I'll let you get back to work," I said.

But she spoke as I turned away. "Detective Pribek," she said, hesitant.

I turned back.

"I noticed... I don't mean to pry, but I noticed that you don't wear your wedding ring anymore."

"Oh," I said. Self-consciously I touched my ring finger. "I'm doing a detail on the street that doesn't allow me to wear a wedding band." I didn't say the words prost.i.tution decoy, prost.i.tution decoy, but Lydia probably got the picture. but Lydia probably got the picture.

Maybe she sensed even more than that. "Shiloh's okay, isn't he?" she said.

Had she read the papers? Did she know about Blue Earth? Her dark eyes gave me no clue.

"I'll tell him you asked about him," I said, evading her question, "the next time I see him."

The next time I see him. I hadn't been back to Wisconsin since the visit I'd made shortly after Shiloh was sent there. We were separated by more than simple geographical distance. Blue Earth lay between us. My trip West to meet his family lay between us. Things that were too difficult to speak about. Even in the good times, Shiloh could be unnervingly quiet; for my part, I was never good at putting feelings into words. I suppose it was inevitable that in hard times we'd fallen back on old ways. We'd fallen silent. see him. I hadn't been back to Wisconsin since the visit I'd made shortly after Shiloh was sent there. We were separated by more than simple geographical distance.

A small storm moved across Hennepin County that night, toward Wisconsin. I slept through the thunder, yet woke abruptly before daylight. A brief moment of disorientation- that night, toward Wisconsin. I slept through the thunder, yet woke abruptly before daylight. A brief moment of disorientation-Where's Shiloh?- and then things came together in my mind, and I realized that the telephone was ringing.

"h.e.l.lo," I said, my voice rusty with sleep.

"It's me."

"What the h.e.l.l, Gen?" My voice had become stronger, but also more irritable. "It's five-"

"I know what time it is in Minneapolis. This is important."

The note of dismay in her voice brought me from awake to alert. "What is it?" I asked.

"You know this is the last thing I wanted to have happen-"
