Kidd said, "When I started looking him up, I found out that he doesn't like public employee unions. Any public employee unions, including police unions. He wants to outlaw them. He debated the head of the Minneapolis union on public television, the Almanac program."

"He's a right-winger," Lucas said. "This is a surprise?"

"No, what's a surprise is, I think the porn file might have come out of a police department," Kidd said.

Lucas wasn't sure he'd heard that right: "What are you talking about?"

"A part of it may have come out of evidentiary files. There's some text with most of the photos, the usual pedophile bullshit. Then there's one says, 'Left to right, unknown adult male, unknown adult male, Mark James Trebuchet, thirteen, unknown female, Sandra Mae Otis, fifteen.' That's the only one with text, but there are about five photos related to that one. I looked them up, those kids-I had to do a little excavating in the juvenile files-and found out that both of them were involved in a prostitution ring busted three years ago by the Minneapolis cops. I assume evidentiary photos wouldn't just be turned loose on the Internet."

"Ah, fuck me," Lucas said.

"I thought you'd be pleased," Kidd said.

"Fuck me. I gotta think about this," Lucas said. "If anybody-anybody-got wind of this, the whole goddamn state would blow up."

"No, it wouldn't. The whole goddamn media-political complex would get its knickers in a twist, and then, after a lot of screaming and slander, life would go on," Kidd said. "You gotta keep some perspective."

"I'll tell you something, Kidd-that might be true if you're an artist," Lucas said. "But if you're a cop, what you see is endless finger-pointing, investigative commissions, legislative inquiries, accusations of obstruction of justice, perjury ..."

"... misfeasance with a corncob ..."

"Yeah, go ahead and laugh," Lucas said. "Listen, keep working this. You think the Smalls file came out of Minneapolis?"

"I have no idea-but those two kids were involved with Minneapolis police. I could dig out the complete juvenile files, if you need them."

"Do that. Uh, how do you do that? I thought they were sealed."

Kidd slid past the question: "Oh, you know. Anyway, what I can't figure out is why the photos of these kids would be inserted in the middle of a child-porn file ... unless maybe the cops got the file when they busted the prostitution ring. And then annotated it? I don't know, that sounds weird."

Lucas thought for a moment, then asked, "This girl in the picture, Sandra, you said she was fifteen? And this was three years ago?"

"Sandra Mae Otis, and yeah, the caption says she was fifteen," Kidd said.

"Huh. Look, I'm in my car. Are you in a place where you could look up her birth date? Like in the DMV files? See if she's eighteen yet?"

"Wait one," Kidd said. Lucas heard his keyboard rattling, and ten seconds later Kidd said, "She's eighteen ... as of last March. March tenth."

"What's her address?"

Kidd read it off, then said, "I'm checking that address on a satellite photo... . Hold on a second ... it looks like a trailer park."

"I know the place," Lucas said. Then, "All right. I don't know what access you have to Minneapolis police files, and I won't ask, but if you should stumble over what looks like the Smalls file ... let me know."

"I'll do that," Kidd said. "Why was Sandra's age important?"

"Think about it for one second," Lucas said.

Kidd thought about it for one second, then said, "Ah. She's an adult now. You can twist her arm until it falls off, and nobody can tell you to quit."

"Perzactly," Lucas said. "And that's what I'm going to do ... if that's what it takes."

TUBBS LIVED IN A prosperous-looking, two-story redbrick apartment building, set up above the street. Still thinking about the porn file, Lucas let himself in with the keys he'd gotten from Morris, skipped the elevator for a flight of carpeted stairs, and let himself into Tubbs's apartment. The living room and bedroom were acceptably neat, for a bachelor who lived alone, and smelled faintly of food that was made in cans and cooked in pots, and also of scented candles. The office was a mess, with stacks of paper everywhere.

Lucas spent only a few minutes in the living room, bedroom, and the two bathrooms, because they'd have been gone through by St. Paul detectives and the crime-scene crew, and they wouldn't have missed anything significant. The office would be where the action was at, because Lucas knew something the St. Paul cops hadn't known: a possible connection to the Smalls problem.

St. Paul had taken out Tubbs's computers, so there wasn't anything to work with but paper. He skipped everything that looked like a report, and started shuffling through individual pieces of paper.

A half hour in, he found a Republican Senate campaign schedule, a half-dozen sheets stapled at the corner and folded in thirds-the right size to be stuck in the breast pocket of a sport coat. The outside sheet was crumpled and then resmoothed, and the whole pack of paper had been folded and refolded, so Tubbs had carried it for a while. There was no equivalent schedule for the Democrats, although Tubbs had been one.

Lucas carried the schedule to a window for the better light and peered at the sheets: there were penciled tick marks against a half-dozen scheduled appearances by Smalls. Interesting, but not definitive. Tubbs had been following Smalls's campaign.

He called Smalls:

"What was your relationship with Bob Tubbs?"

"Tubbs?" Smalls asked. "What're you doing?"

"Trying to figure out why he was tracking your campaign."

"Tracking ... Well, I don't think you could draw any conclusions from that," Smalls said. "That's what he did for a living."

Lucas read off the list of the appearances Tubbs had been tracking. "Any reason why he'd pick those four?"

After a moment of silence, Smalls said, "The only thing I can think of is that I was out of town on all of them."

"Of course," Lucas said. He should have seen it.

"My God, Davenport, the papers say Tubbs has disappeared," Smalls said. "What does this have to do with the porn thing?"

"I don't know-but I was told that he went through your campaign office from time to time," Lucas said.

"Not while I was there," Smalls said. "But, you know ... political people hang out."

"What about Tubbs? Did he hate you?"

"Oh, not really. We didn't particularly care for each other," Smalls said. "He was pretty much a standard Democrat operator. He also lobbied some, so he had to suck up to Republicans as well. He was just one of those guys doing a little here, a little there. He was supposedly a bagman for one of our less revered St. Paul state senators. Don't know if that's true or not, but I suspect it was."

"Did he do dirty tricks? Could he have come up with this porn idea?"

"Well, you know, yeah, probably," Smalls said. "He'd do opposition research, try to find a picture of you picking your nose, or waving your arm so that if it was cropped right, you looked like you were doing a Hitler salute."

They talked for a few more minutes, and when Lucas got off the phone, he started taking the apartment apart. It hadn't occurred to him until Smalls mentioned the possibility that Tubbs had been a bagman, and that he might have been involved in dirty tricks, but the fact was, nothing the least bit discreditable had been found in the apartment by either the St. Paul cops or the crime-scene people. No porn, no cash ... and looking around, Lucas hadn't found any employment contracts, no car titles, no leases, no legal papers of any kind.

Tubbs might well have a safe-deposit box somewhere, but Lucas thought there was a good chance that he'd have a hidey-hole somewhere in the apartment, somewhere he could get at important papers quickly. After a quick survey, in which he didn't spot anything in particular, he unplugged a lamp and carried it around the apartment, testing all the outlets. Fake electric outlets, though opening to small caches, were both innocuous-looking and easy to get at. In this case, all the outlets worked.

He rapped on the wooden floor and got a hard return: the building was a steel-reinforced concrete structure, so there were no holes in either the floor or the ceiling, which looked like genuine plaster. An access panel on the back wall of the bathroom looked promising, because it appeared to have been removed a few times-probably at least once by the crime-scene crew. He found a screwdriver in a tool kit that he'd seen in the kitchen, and removed the panel, and found sewer pipes and the usual inter-wall dust and grime. He put the panel back on and moved to the closets, checking for fake side panels.
