They don't let me leave the library.
The four men—Basílio, Eustáquio, Leôncio, and Nemésio—form a perimeter around me like I'm a threat that needs containing. The party continues outside. Music. Laughter. The beautiful people pretending power doesn't have teeth.
"Your father didn't die in an accident," Leôncio says, settling into a leather chair like he's about to deliver a lecture. He pulls out a tablet, and screens light up with photographs. My father's car. The bridge. The Pinheiros River. "He was executed. Arranged to look like an accident. Engineered by a federal agent named Rafael Costanza Teixeira."
I stare at the photographs. I've seen them before—not these exact ones, but variations. News reports. Police documentation. The narrative I've believed for five years.
All a lie.
"Why would—" I start, but Eustáquio cuts me off.
"Because your father discovered something Rafael wanted hidden," he says. His Russian accent is thick when he speaks, rolling over the words like he's tasting them. "Money. Billions. Moving through shell companies. Moving through government accounts. Moving through channels that Rafael was controlling."
"My father was investigating you," I say to Basílio. "I have the evidence. I have documents showing—"
"You have fragments," Leôncio interrupts. "Pieces of a larger picture. Your father was mapping one thread of a web that spans twelve countries and involves hundreds of people. He found enough to be dangerous. Not enough to be unstoppable."
Nemésio sits down across from me. His expression is haunted in a way that suggests he knows something the others don't want me to know yet.
"Rafael had him killed," Nemésio says quietly. "And then he spent the next five years hunting anyone who might have your father's complete research. Which includes you."
"I don't have it," I say. "Whatever my father gathered, I don't have it."
"We know," Basílio says. He moves behind my chair, and his hands find my shoulders. The touch is possessive. "Which is the only reason you're still alive."
The implication hits me like a blade. If I had his research, they would have already destroyed me. If I had what Rafael was hunting, I'd be dead.
"How long have you known about me?" I ask.
"Three months," Nemésio says. "We were investigating Rafael's operations and discovered that he was hunting someone. A girl. A woman. Someone who had access to research that could destroy him. Nemésio realized that person was you. So we decided to get to you first."
"The invitation to the gala was from you."
"Yes," Basílio says. "We brought you here to keep you safe. To understand what you know. To figure out if you're an asset or a liability."
I stand up from the chair, and Basílio's hands release me. "This is manipulation."
"Yes," Leôncio agrees. "But it's also protection. Rafael was coming for you with or without our intervention. We simply moved faster."
"Why would you protect me? I'm investigating you."
"Because," Basílio says, "you have something we need. Information about your father's final days. Details about what he discovered. Knowledge about who he was connected to before he died."
"I don't know anything."
"Then you're useless to us," Eustáquio says flatly. "Which means we have no reason to keep you alive."
The threat is stated without inflection. Without anger. Just fact.
"Unless," Nemésio says, and there's something almost gentle in his voice, "you agree to work with us."
"Work with you how?"
"Help us understand what your father was building," Leôncio says. "Help us identify which government officials were complicit. Help us trace the money. Help us understand how Rafael consolidated power."
"And if I refuse?"
"You won't," Basílio says. He moves to the window and looks out at the party. "Because refusing means dying. Refusing means Rafael wins. Refusing means your father's death means nothing."
I look at the four of them—the enforcer, the strategist, the angel with secrets, the patriarch with scars. These are the men I came to expose. These are the criminals I infiltrated a party to investigate.
And they're offering me protection.
"I need to think about this," I say.
"You have ten minutes," Leôncio replies.
They leave me alone in the library. I pace the length of the room, my mind racing through possibilities and consequences. Every scenario ends the same way: if I refuse, I die. If I accept, I become complicit in crimes I haven't even investigated yet.
My phone buzzes in my clutch. A message from an unknown number:
Unknown: Don't trust them. They're using you. Call me. Rafael.
My hands go numb.
Rafael knows I'm here. Rafael knows I'm with them. Rafael is watching, waiting, hunting.
Another message appears:
Unknown: You don't have to run anymore. I can protect you. Just call.
I delete both messages and destroy my phone. Not literally—I smash it against the marble fireplace until the screen cracks, the circuits sparking. Destroying evidence. Destroying connection to the outside world.
When they return, Basílio finds me standing in the middle of the library, surrounded by the pieces of my phone.
"I'll do it," I say. "I'll work with you. But I have conditions."
"You're not in a position to negotiate," Eustáquio says.
"I am," I reply. "Because I'm the only one who understands my father's work well enough to decode it. I'm the only one who knows the connections he made. I'm the only one who can link everything together. Which makes me valuable. Which means you need me more than I need you."
Basílio smiles. It's not a happy smile. It's the smile of a predator recognizing another predator.
"What are your conditions?" he asks.
"I need access to everything you know about Rafael. Every transaction. Every connection. Every crime. I need to understand the complete picture before I start giving you information."
"Agreed," Leôncio says.
"I need protection. Real protection. Not just from Rafael, but from anyone else who might be hunting me."
"You'll have it," Eustáquio says.
"And I need to understand what this actually is," I say, looking at each of them. "Are you protecting me because you care about justice? Because you want revenge against Rafael? Because you want to build your own empire?"
"All of the above," Basílio says. "And also because you intrigue me. And also because I've decided you're going to belong to me."
The statement is made with such certainty that it doesn't sound like obsession. It sounds like inevitability.
"That's not happening," I say.
"We'll see," he replies.
Nemésio steps forward. "When we leave here, you're not going back to your apartment. You're not going back to your old life. You're coming with us to a secure location where we can keep you safe."
"For how long?"
"Until this is over," Leôncio says.
"And when will this be over?"
No one answers.
They take me out through the service entrance, avoiding the main ballroom. The valet brings around black SUVs with tinted windows. We drive through São Paulo at midnight, and I watch my old life disappear in the side mirror.
As we're pulling up to the building—a modernist tower in Jardins—Basílio leans over and speaks quietly in my ear.
"You made the right choice," he says.
"Did I?" I ask.
"We'll find out," he replies.
The penthouse is on the top floor. Floor-to-ceiling windows overlook the city like it belongs to someone else. The interior is minimalist—white, grey, steel. Beautiful and suffocating in equal measure.
"This is your space now," Basílio says, gesturing to a guest suite. "You have access to most of the apartment. But that east wing is off-limits."
"Why?"
"Because I said so," he replies, and there's no apology in his voice.
"My phone," I say. "I destroyed it. I need a new one."
Eustáquio produces a phone from his pocket and hands it to me. "It's clean. Encrypted. No outside contact."
"You're trapping me."
"We're protecting you," Basílio corrects.
I take the phone and feel the weight of it. It's a tether. A symbol. Proof that I've traded one cage for another.
Before I can say anything else, my new phone buzzes with a message:
Unknown: Welcome to the penthouse, Isolda. We need to talk about your father.
I show the message to Basílio. His expression doesn't change, but something shifts in his eyes.
"Who sent this?" I demand.
"Someone who shouldn't have access to this phone," he says quietly.
He takes the phone from my hand and makes a call. His voice is controlled when he speaks, but there's steel underneath. "We have a security breach. No. Now."
He hangs up and looks at me.
"It seems," he says, "that there's someone else in this city who's been waiting for you to surface."
"Who?"
"The person who's been running this entire game from the beginning," Nemésio says. His expression is haunted. "The person we've been trying to take down for five years. The person who's more powerful than any of us."
"Who?" I ask again, and my voice is smaller now.
Basílio doesn't answer. He just pulls up a video on the screens that line the penthouse walls. The footage is from this evening—from the gala. But it's not footage of me with Basílio.
It's footage from the library. From before they entered. From when I was alone with Basílio.
Except I wasn't alone.
In the corner of the frame, barely visible, is a man watching from the shadows. And when the video zooms in, I see his face.
I see him, and my entire world stops.
Because the man in the shadows is my father.
And he's smiling.
