In recent months they've fought-successfully-pitched battles against Guatemalan special forces troops to defend airstrips used for bringing in cocaine, and now Adn has word that there are over four hundred Zeta operatives in the country focusing on Guatemala City and the Peten, the province on the border with Mexico, and have advertised for ex-soldiers on pirate radio stations.

It's significant-70 percent of the cocaine that flows through Mexico comes in via Guatemala.

All the cartels have used Guatemala for years.

It goes back to the old "Mexican Trampoline" days of the '80s, because flights from Colombia needed a place to refuel before flying into Guadalajara. With the current war on drugs, Guatemala has become even more important, as a market, but also as a transshipment point. Cocaine flown into the Peten can simply be carried into Mexico and moved up to the border from there. Now the Zetas are forcing peasants from their land so they can use it as a string of bases.

The Guatemalan government has sent a thousand troops, with armored vehicles, helicopters, and surveillance equipment, into the Peten. The Peten has always been neutral territory-safe and quiescent-and now Ochoa, in making a move to control it, has brought government attention, not to mention the DEA.

It can't be allowed-Adn's cocaine imports depend on El Salvador and Guatemala, and he can't yield either to the Zetas.

Adn walks out of the kitchen onto the broad stretch of lawn and walks down toward a grove of fresno trees at the bottom of the slope. The morning is cool and quiet, with birdsong just starting as the sun comes up.

Barely aware of the sicarios that follow from a discreet distance, Adn walks into the grove. It's peaceful here, it feels so far away from the conflicts and strife that inhabit the rest of his life.

Eva is well, but Eva is also not pregnant.

Which seems to be the central fact of her life.

If sex with a beautiful twenty-year-old woman can be deemed a chore, that's what it's become, a chore-Eva running around with a thermometer in her mouth, checking calendars and clocks, summoning him to perform when the moment is ripe, suggesting new positions not for enjoyment but for the efficiency of physics.

Eva is frustrated and fearful-despite his assurances to the contrary-that he'll leave her.

And she's restless.

He understands.

Life on a remote finca is not exactly ideal for a vivacious girl her age. Adn understands that she feels like a prisoner here, even with the swimming pool, the home gym, the horses, the satellite dish, and Netflix. She goes on shopping trips to Badiraguato and Culiacn, but he knows that she wants to hit the clubs in Mazatln and Cabo. He tries to facilitate that, but it's difficult, and she doesn't appreciate the level of organization and planning even a quick trip off the finca requires.

She misses her friends, and he brings them in from time to time, but each visitor is a potential security risk, and with two wars going on and the FES rampaging through the narco ranks, he can't afford unnecessary risks.

As a sop, he's arranged for her to go to Mexico City every few weeks for a few days, and she's leaving later this morning, but he knows that it's a temporary respite at best.

The issue is that she's bored, has nothing to do with her time, and refuses to grow up. Some women let the vicissitudes of life make them hard and bitter, but Eva has gone in the other direction-willfully nave, consciously unaware, almost defiantly childlike. Always cheerful, perpetually, annoyingly "bubbly," still the virgin bride in bed-enthusiastic, energetic, unskillful.

The brutal fact is that Eva has failed in the one job that she was required to do-produce an heir.

"She has given you a child," Magda said during one of their assignations in Badiraguato. "Herself."

"Very funny."

"So, seriously, what are you going to do?"

"What are you suggesting?"

"Get a new wife." She let that sit for a second and then continued, "Oh, come on, you don't love her. You can't tell me that you love her."

"I've grown fond."

"I'm fond of my golden retriever," Magda said. "Eva's a child, and she gets younger every day. It's almost creepy. Seriously, I wonder about her mental health, don't you?"

"It's a hard life for a woman."

"Thank you for telling me. I didn't know," Magda said.

How would Nacho react, Adn wonders, if I do divorce his daughter? Would he accept it, or use it as a pretext to break the alliance? No, that's too direct for Nacho-he would pretend to accept it and then use the power base I gave him in Tijuana to move against me. He'd go back to his old allies in Jurez and start stirring up a rebellion, while denying it all the time.

Adn has the fleeting thought that he should kill him now. Easy enough to blame on the Zetas. Then after Nacho is in the ground and a suitable mourning period, send Eva packing, with enough money, of course, to live in the manner to which she's become accustomed.

He walks back up to the house.

Eva isn't up yet, and for some reason it annoys him. He'd like to wake her up on the pretext that she's going to miss her flight, but as they own two Learjets with crews standing by it wouldn't work.

He watches her sleep.

Magda's right, Adn thinks.

She's a child.

- Like any civil war, the conflict between the CDG and the Zetas has been extraordinarily vicious.

And it can only be called a war.

Whereas gangs of sicarios used to move covertly, now trucks with hundreds of armed men openly roll on the roads of northern Tamaulipas as machine-gun and grenade attacks erupt in Nuevo Laredo, Reynosa, and Matamoros, as well as the small border towns along La Frontera Chica between Matamoros and Laredo.

"The Little Border" is strategically important for three reasons.

One, it lies between the two strongholds of the CDG and the Zetas, Matamoros and Nuevo Laredo respectively.

Two, it lies along the lucrative drug-smuggling border into the U.S.

The third reason has nothing to do with drugs at all, but with that other precious commodity of the twenty-first century.

Energy.

La Frontera Chica contains the Burgo Basin, rich in natural gas. Mexico's national energy company, Pemex, has been exploring and drilling there for years, and there are almost 130 natural gas stations pumping now, with another 1,000 as yet to be exploited. American oil companies are eager to invest and start drilling. The cartels have long wanted to get into the energy business, and La Frontera Chica is the perfect place to do it.

So the little towns like Ciudad Mier, Camargo, and Miguel Alemn become battlefields.

It started in Mier, when fifteen pickup trucks marked with the CDG logo roared into town. Sicarios spilled out of the trucks and opened fire with machine guns on the town police station. Then the sicarios went in and hauled out six policemen, who were never seen again.

The CDG set up roadblocks, sealed off the town, and started the executions of Zeta loyalists, lining them up against a wall in the town square. The dead were decapitated, their heads set in a corner of the plaza. One young man, accused of being a Zeta lookout, screamed as his arm was sawed off before he was hanged from a tree.

The fighting went on for six days.

The Zetas struck back, and it became a battle of sniper versus sniper in Mier, Camargo, and Miguel Alemn. For all practical purposes, northern Tamaulipas could be Iraq, Gaza, or Lebanon as the rival factions fought in the streets, burned shops and houses, and evicted people from their homes.

Barricades went up.

Towns became ghost towns.

- Ochoa doesn't call.

Gordo Contreras does.

Adn says to Magda, "You owe me a hundred dollars."

"I would have sworn it would have been Ochoa."

"He's too arrogant."

"You know the CDG is going to lose," Magda says, "and you don't care. You'll give them just enough help to keep the war going until both sides bleed each other out. Then you'll step in and take Tamaulipas. Matamoros, Reynosa, Laredo-all of it."

Adn shrugs. As usual, she's read both him and the situation exactly.

"Have you thought about your price?" Magda asks. "Gordo will think that you'll settle for just having an ally against Ochoa, but I think we could get more. Free use of their ports. It would be an easier route to the European market."

"You're still on that?"

"You should be, too," Magda says.

- It only makes sense, Magda thinks. A kilo of cocaine sells for about $24,000 in the United States, in Europe, more than twice that. Even after cutting in European partners and paying the usual bribes, the profit margin is simply too good to ignore. If Adn doesn't want in on it, she's going to do it anyway, although his protective umbrella would be useful.

"You're talking 'Ndrangheta," Adn says, referring to the Italian Mafia that dominates the drug trade in most of Europe. "The CDG has them wrapped up."

"Because we haven't made the effort," Magda answers. "If I went there, I'm sure I could persuade them to work with us."

Not because of her undoubted sex appeal, but because it's to 'Ndrangheta's advantage to have more than one source of supply. And the European market, especially for cocaine, is rapidly expanding. Most of the heroin still comes in from Afghanistan and Pakistan via Turkey, the marijuana from North Africa via Morocco, but the CDG's cocaine monopoly could be pried open. And if she can buy at $5,500 and sell at $55,000, well, do the math.

Besides, she'd like to see Europe again, through her own eyes instead of as a rapt naf under Jorge's tutelage. She could mix in some museums and galleries, and maybe a little shopping, with business. The fact is, she could use a vacation-only now does she understand Adn's disciplined, busy days back at Puente Grande-the thousand and one details of running a multimillion-dollar enterprise.

La Reina Amante, indeed.

"But if you don't want in, I'll do it on my own. Just get the CDG out of my way. By the way, have you knocked up your queen yet?"

"Be nice."

"I am being nice," Magda says.

"Not yet."

"They say that the doggie position-"

"For God's sake, Magda."

"I don't remember this puritanical attitude in Puente Grande," Magda says. "Let's fuck-I'll give you your hundred dollars in trade."

"In her house?"

"There must be other beds, if you're squeamish," Magda says. "Oh, never mind, if you're going to be such a little househusband about it."

He grabs her.

That night, Gordo agrees that Adn will have free use of his ports in Matamoros and Reynosa, and introductions to his drug network in Europe.

Adn agrees to do what he was going to do anyway-continue to fight the Zetas.

- Eva lets herself into the condo in Bosques de las Lomas and flops down on the bed.

Her bodyguard Miguel brings in her bag. "Where do you want this?"

"On the bed," Eva says. "Where I want you."

Miguel smiles. He sets the bag at the foot of the bed and then lies down on top of Eva.

She unzips the fly of his tight blue jeans. "This is what I want, right here. Hurry. I thought the flight would never end."

Eva makes him hard with her hand, although it doesn't take much. She uses her other hand to unzip her own jeans and then she wriggles out of them. She's already wet and he slides into her easily.

"That's good," she says. "That's so good."

Miguel is twenty-five and strong and lithe and muscled and impatient for his own pleasure, but she likes that. She wants to be taken, and as she feels him near his climax and start to pull out, she grabs his shoulders and holds him inside her and says, "It's all right, you can come in me."

"You sure?"

"The pill."

After, she lies beside him and starts to laugh.

"What?" Miguel asks.

"Do you know what my husband would do to you," she says, "would do to that beautiful cock, if he knew where it had just been?"

"I don't want to think."

"But you're the one who's supposed to tell him these things," Eva said. "You're his spy, aren't you? Are you going to tell him?"

"No."

"Good," Eva says, "because I like this beautiful cock right where it is."

She rolls over and takes him in her mouth.

"Can you go again," she asks, sitting up. "Can you?"

"If you keep doing that."

Eva keeps doing that.
