“You were with my son when he died,” Irma says.

“Yes,” Keller says. “It was quick. He didn’t suffer at all.”

Irma takes his hand and closes her eyes.

“Your son was a brave man,” Keller says. “You should be very proud of him.”

“I am,” she says. She opens her eyes. “But tell me, was it worth it?”

Keller squeezes her hand.

He stays for a couple of hours, talking with Córdova’s family. A few of the cousins are there, and Orduña, and eventually they start talking about Angulo as a boy, and a teenager, and then the funny stories start, and the quiet laughter, and more tears. It’s twilight when Orduña gets up to leave for the long drive to the airport and the flight back to Mexico City.

Marisol looks at Keller and says, “I’m driving back.”

“To Valverde?” It’s a long drive. Hours on a dangerous road through dangerous country.

“Yes.”

“Alone?” Keller asks.

She thinks about it for a few seconds before saying, “I could use some company.”

Keller goes to Orduña to tell him that he won’t be driving back with him.

Orduña smiles. “La Médica Hermosa? I can’t say I blame you.”

“We’ve known each other for a while.”

“I know all about it, Arturo.”

“You have a problem with it?”

“Only envy,” Orduña says. “Go with God.”

When Keller and Marisol go to leave, Irma insists on getting up and seeing them to the door.

“Thank you for coming,” she says.

“It was my honor,” Keller answers.

She takes Keller’s hand again. “Arturo, you do not avenge a murder by killing—you avenge it by living.”

It’s ninety miles on Carretera 2 back to Valverde—every car and truck potentially full of narcos, potentially deadly, and army checkpoints that are just as dangerous. The soldiers at the checkpoints know Marisol and are prepared to give her a bad time but are confused by the gringo behind the wheel, especially when he shows them the DEA badge.

“They’re afraid of you,” Marisol says as they pull away from the checkpoint outside of Práxedis.

Keller shrugs.

“We don’t think much of the army here in the valley,” Marisol says.

She tells him the whole story—the land seizures, the arrests, the torture. If it weren’t Marisol telling him, he’d think it was an exaggeration, liberal paranoia. But Marisol he believes, even when she concludes, “The army isn’t fighting the cartels, the army is a cartel.”

Keller tries to take it all in.

Then Marisol aks, “What were you doing with the FES? I thought you were some kind of policy wonk.”

“No you didn’t,” Keller answers.

“No, I didn’t,” she says. “I only hoped.”

“I can’t do this with you, Marisol.”

“Do what?”

“Play the cop-who-can’t-talk-to-his-woman-about-what-he-does scene,” Keller answers. “Played it once already. It didn’t work.”

“Then talk to me,” she says. “Tell me.”

He knows it’s one of those moments. He either doesn’t answer, or comes up with some half-clever evasion that won’t fool her, and their relationship is over for good. Or he tells her, and their relationship is…what?

“I go after narcos,” Keller says. “I kill them.”

“I see.”

Cold.

“And I’m not going to stop until I get Barrera.”

“Why him so particularly?”

Keller starts to talk and then he can’t stop. He tells her everything—about his friendship with the young Adán Barrera, how Barrera tortured and killed his partner Ernie Hidalgo. He tells her about Barrera throwing two children off a bridge to their deaths. He tells her about Barrera ordering the slaughter of nineteen innocent men, women, and children to punish a nonexistent informer that Keller invented to protect the real one.

“So you blame yourself,” Marisol says.

“No, I blame him,” Keller answers. “I blame both of us.”

“And this is why you do what you do.”

“He killed people I loved,” Keller says. “He’s evil. I know that’s an old-fashioned concept, but I’m an old-fashioned guy. The truth of the matter is that he wants to kill me, too, and that’s why I can’t be with you.”

They sit silently until they get to Valverde. Keller is shocked by the look of the little town—houses and shops boarded up, bullet-riddled stucco, army patrols rolling down the street in green trucks with searchlights sweeping to the front and sides.

She directs him to her house, an old adobe at the edge of town, and he pulls into the gravel driveway. Gets out of the car, opens the door for her, and asks, “Where’s the hotel?”

“Do you prefer the Hilton or the Four Seasons?” she asks. “Another awkward joke. There’s no hotel…I thought that you’d stay with me.”

“I don’t want you to think I was expecting that,” Keller says.

“For God’s sake, Arturo, come in,” she says, “and if you mumble one word about sleeping on the couch I’ll strangle you.”

Keller follows her into the house and then into the bedroom, where Marisol starts to unbutton the black dress. “I’ve had enough of death today, I’m tired of death. Señora Córdova was right—you take revenge by living.”

She steps out of the black dress and hangs it up in the closet.

“I want you inside me,” Marisol says. “Let tomorrow worry about tomorrow.”

—

Later that night, Zeta gunmen smash into Córdova’s house.

His aunt, brother, and sister are asleep on the living room sofas and the Zetas shoot them first. Then they burst into the bedroom and blast Irma Córdova to death in her bed.

Before they leave, the Zetas take photos of the bodies and post them on the Internet with the message THIS WAS FOR DISRESPECTING OUR FRIEND DIEGO, YOU FES MOTHERFUCKERS. SINCERELY—THE Z COMPANY.

—

As they absorb the tragic news in the morning, Keller and Marisol come to a silent understanding, an acknowledgment that there is such a thing as evil, that the world holds horrors beyond their previous imagining.

There is an unspoken resolution between them now.

That they will face these horrors together.

And that they will live.

January 2010

Keller draws the cocaine up through the cotton into the hypodermic needle. He has three hundred of the small cocaine ampules, known as colmillos, ready to go.

He shows the needle to “Mikey-Mike” Wagner, a Zeta-affiliated meth dealer out of Horizon City, Texas, southeast of El Paso.

Mikey-Mike is terrified and he should be.

The day after the slaughter of the Córdova family, Orduña formed a new unit inside the FES, secret even from the navy, made up of the best of the best. Called “Matazetas,” the men would be clad in black.

Their sole mission reflects their name.
