“None he named today,” Baxter replies. “Maybe he’s protecting somebody.”

“Someone in the closet,” says SAC Bowles.

“What about Juan?” I ask. “The butler or whatever he was?”

“We didn’t know about him till today,” says Baxter. “NOPD’s talking to him now. He tried to slip out, but they got him. Looks like an illegal. Salvadoran.”

Now I realize why he looked familiar. I spent a good bit of time in El Salvador, seeing faces much like his.

“What else do we have?” asks Kaiser. “What about soldiers Wheaton served with? Convicts Gaines shared cells with?”

“I’ve got two lists,” says Baxter. “I thought you might want to talk to the Vietnam vets.”

As the men work out these details, a strange epiphany occurs at the dark center of my mind. The paradox of expert opinion versus physical evidence has been slowly working itself out there. “I’ve thought of a third possibility,” I say quietly.

Kaiser waves his hand to silence the others, and they turn to me.

“What is it?” he asks.

“What if one of the four suspects we saw today is doing the murders, but doesn’t know he’s doing them?”

No one responds. Baxter and Kaiser look stunned by the suggestion, but Dr. Lenz is sanguine.

“How did you come up with that?” asks the psychiatrist.

“The old Sherlock Holmes theory. After you exclude all impossibilities, whatever you have left is the solution, however improbable it may seem.”

“We haven’t excluded the other possibilities,” says Baxter. “Not by any means.”

“We’re not getting anywhere with them, either.” Kaiser looks thoughtfully at Lenz. “What about that?”

The psychiatrist makes a noncommittal gesture with his hands, as though considering the idea for the first time. “You’re talking about MPD. Multiple-personality disorder. It’s extremely rare. Much rarer than films or novels would have the public believe.”

“In all my time at Quantico, I never saw a proved case,” Kaiser says.

“When it does happen,” says Bowles, “what causes it?”

“Severe sexual or physical abuse during childhood,” says Lenz. “Exclusively.”

“What do we know about the childhoods of the three men?” I ask, recalling Thalia’s confession of sexual abuse. “We know Laveau had that kind of problem.”

“Not much,” says Baxter. “Wheaton’s childhood is pretty obscure. All we really have is the standard bio that appears in articles. Certainly nothing about abuse. We do know his mother left the home when he was thirteen or fourteen, which could be a sign of some kind of abuse, but we don’t have details. And if the children were being abused, why not take the children with her?”

“We should ask Wheaton that,” says Kaiser.

“What about Leon Gaines?” I ask. “I’ll bet there was some abuse there.”

“Undoubtedly,” says Lenz. “He spent time in a juvenile reformatory, which is a high-percentage indicator for abuse. But the kind of radical psychological break I’m talking about has its roots much earlier in a child’s life.”

I look at Baxter. “Didn’t you say his father did time for carnal knowledge of a minor? A fourteen-year-old girl?”

Baxter nods. “That’s right. We’d better dig deeper on the father.”

“Frank Smith,” says Kaiser. “What do we know about his childhood?”

“Wealthy family,” says Lenz. “Not the kind where abuse would be reported. I’ll try to contact the family doctor.”

As we ponder this angle in silence, the SAC’s phone rings. Bowles goes to his desk, then motions Baxter to the phone. Baxter identifies himself, asks some questions I can’t quite hear, then hangs up and returns to us, a tight smile on his lips.

“What is it?” asks Kaiser.

“Frank Smith’s Salvadoran butler just told NOPD detectives that Roger Wheaton has visited Frank several times for extended periods at night. He’s stayed over twice.”

Kaiser whistles. “No kidding.”

Baxter nods. “And get this. On those nights, he’s heard them screaming at each other. Heard it through the walls.”

This image is hard for me to reconcile with what I’ve seen of both men, but Dr. Lenz looks more excited than I’ve seen him to date.

“We’ve got to see both of them again,” he says.

“No doubt,” agrees Baxter. “How should we approach them?”

Lenz purses his lips but says nothing.

“I think I should talk to Frank Smith,” I say firmly.

They all look at me. “Alone?” asks Baxter.

“He invited me back, didn’t he? That’s your best shot of finding out about those visits.”

“She got Laveau to trust her,” Kaiser reminds them. “I say let her do it.”

Baxter looks uncomfortable, and turns to Lenz for an opinion.

The psychiatrist shrugs. “I know you’d prefer some other way, but Smith really responded to her. We have to go with the best odds.”

Baxter sighs. “Okay. Jordan will talk to Smith.”

“Arthur and I can see Wheaton,” Kaiser says. “We should have the phone company fault their lines. We don’t want any more warnings passing between them.”

“Sounds like a plan,” Baxter concludes. “How much of this do we give the task force?”

“All of it,” says Kaiser. “They’ve proved trustworthy so far. If we hold out without reason, we’re only screwing ourselves.”

“The multiple-personality theory as well?” asks Lenz.

“No,” says Baxter. “That’s the kind of exotic speculation they rib us about, so let’s play it down unless we have some reason to think it’s the right track.” He glances at me. “Something other than the Sherlock Holmes theory, at least.”

A belated smile tells me he said this in fun.

“Any last questions?”

Kaiser flicks up his hand like a schoolkid. “This morning you said you had that Argus computer program chewing on digital photos of the abstract Sleeping Women. Has it turned up any recognizable faces?”

“They’re looking more human,” says Baxter. “But none matches any murder victim or missing person in the New Orleans area over the past three years.”

“Who’s making those comparisons?”

“Couple of agents I borrowed from Counter-intelligence,” answers the SAC. “Good men. Twenty years in, between them.”

“I’d like to see whatever Argus spits out,” says Kaiser. “I’ve studied a lot of victims’ faces in the past few months.”

“Will you see to that, Patrick?” says Baxter.

Bowles nods. “We’ll get you copies of every image e-mailed from Washington, as we decrypt them. I hope you’ve got a lot of time on your hands.”

Baxter looks at his watch. “We need to go.” Turning to me, he says, “Jordan, more than ever, we need you to stay isolated from any friends from your former life here.”

“No problem. I’m beat. I’m going back to my hotel, ordering room service, and racking out.”

“Do you trust your brother-in-law to keep quiet?”

“No problems there.”

His eyes linger on mine. “I’ve already gotten Wendy a room next door to yours. Just yell out if you need help.”

I nod, preferring Wendy Travis to a stranger, though I sense potential complications from her presence.

Baxter slaps his thighs and stands, and the other men follow suit like football players rising from a huddle.

“Let’s go talk to the boys in blue,” says Baxter.

“Black and blue,” says Kaiser. “The NOPD wears black and blue.”

Baxter leads the way to the door, headed for the Emergency Operations Center, which I have yet to see. Bowles follows, and Lenz falls into line behind him. Only Kaiser hangs back, contriving to walk beside me as I move toward the door.

“So, you’re going to bed early?” he says softly.

“Yes.” I pause at the door and watch the others move down the hall. “But maybe not to sleep. Call me from the lobby.”

Looking up the hallway, he touches my hand and squeezes slightly, then without a word follows Dr. Lenz. I give him a few seconds, then go around the corner to the elevators, where I find Wendy waiting for me.
