'But back up a minute,' said Michelle. 'So what if Willa is adopted? Why would Tuck not want to admit that? It's not like adoption is illegal.'
'It might make a difference if the mother's identity is an issue somehow,' said Sean slowly.
'Or maybe the father's,' pointed out Michelle.
The three stewed on that for a few silent moments.
Waters finally spoke up. 'And the First Lady didn't know anything about this? Her own brother?'
'So she claims,' answered Sean.
Waters gave him a sharp glance. 'But you don't believe her?'
'I didn't say that.'
'So you do believe her?'
'I didn't say that either.' Sean sat back and stared at the FBI agent. 'So anything on your end?'
Water's face went slack. 'I'm sorry, I didn't know this was a two-way conversation.'
'If we work together the odds of getting Willa Dutton back alive might go up a little bit.'
Waters still didn't seem convinced.
'Look, I told you, I don't care who gets the credit or the glory. We just want the girl back.'
'You can't possibly have a problem with that deal,' said Michelle.
Waters finished his beer and eyed her curiously. 'Was your mother really murdered?'
'Yes.'
'Any leads?'
'The chief suspect is my dad.'
'Jesus!'
'No, his name's Frank.'
'Shouldn't you be focused on that?'
'I'm a woman.'
'Meaning what?'
'Meaning, unlike men, I can handle more than one thing at a time.'
Sean tapped his arm. 'So what's it gonna be, Chuck?'
Waters motioned to the waiter for another round, then said, 'We found a hair on Pam Dutton that didn't belong to her or anyone else in her family.'
'I thought the trace DNA didn't produce a criminal database hit,' said Michelle.
'It didn't. So we ran a different test on the hair. An isotopic exam looking for geographic clues.'
Sean and Michelle exchanged glances.
'What'd you find?' asked Sean.
'That the person whose hair it was has eaten a diet high in animal fats for years but also one with plenty of vegetables.'
'What can you deduce from that?' asked Michelle.
'Not a lot, although the typical American diet doesn't include a lot of veggies anymore.'
'Were the fats or vegetables processed?' asked Michelle.
'Don't think so, no. But the sodium levels were high too.'
Sean looked at Waters. 'Maybe a farm? They slaughter and eat their own meat? Cure it with salt, maybe. Harvest crops. Preserve and can them, again with salt.'
'Maybe,' said Waters. 'They also found something else in the exam.' He hesitated.
'Don't keep us in suspense,' joked Sean.
'The water the person drank. That's reflected in the hair isotope too. The lab narrowed it down to a three-state area.'
'Which three?'
'Georgia, Alabama, and Mississippi.'
'That dovetails with the mail triangulation,' noted Michelle.
'Three across,' said Sean softly, staring at his drink. 'Three states right in a row.'
'Apparently both the rain and drinking water down there has some pretty distinctive markers,' said Waters. 'And it's been mapped pretty comprehensively over the years. That's why the lab feels very confident about the findings.'
'Could they tell if it was well or city water?'
'Well,' said Waters. 'No commercial chlorine or other purifiers like that.'
'So that means rural?'
'Possibly, although there're certainly some subdivisions on well water down there. I used to live in one of them before I got assigned here.'
'And with diets high in unprocessed animal fat and veggies?' exclaimed Sean.
'Okay, quite possibly rural. But with all that, it's still a big area to focus on.'
'But those states don't square with the Koasati piece,' said Michelle. 'Texas or Louisiana.'
'But the Koasati are from Alabama originally,' pointed out Sean.
'Originally, yeah, but not now.'
'Can you still run down the Koasati angle?' he asked Waters.
Waters nodded. 'I'll have agents down there get started immediately on it.' He studied them both. 'So is that all you know?'
Sean finished his drink and rose. 'It's all we know that's worth sharing.'
They left Waters to his second beer and walked back to the SUV. Along the way Michelle's phone buzzed. She looked at the screen.
'Who is it?' asked Sean.
'My caller ID says a Tammy Fitzgerald.'
'Who's she?'
'Somebody I don't know.'
She put the phone away and said, 'You didn't mention the letter the First Lady received to our little FBI chum.'
'That's right, I didn't.'
'But why not?'
'Because I'm willing to let her come to her senses before I throw her to the Feds on an obstruction charge. That'll probably screw the election for the president too. And he's done a good job.'
'Are you kidding me? Who the hell cares what it does politically to the First Couple? What if it costs Willa her life? Isn't that what you care about, getting Willa back? Or was that a load of shit you were shoveling Waters back there?'
Sean stopped walking and turned on her. 'Michelle, I'm doing the best I can here, okay? It's complicated. It's damn complicated.'
'It's only complicated if you make it so. I like to keep things simple. Find Willa, any way I can.'
He was about to say something when he stopped and stared over her shoulder.
Michelle finally turned to see what he was looking at.
There were two men across the street dressed in Army cammies walking along.
'Damn.'
Michelle turned back to look at Sean. 'Damn what?'
'You said you thought the guy you saw with the MP5 was wearing military-level body armor?'
'That's right.'
'Yeah, that's right,' said Sean.
