The building is dark, and no one seems to be on duty. I go until the ceiling starts to get higher and the sound of my footsteps changes. Then I emerge into the main atrium, and I freeze, my mouth open.

The institute’s main lobby could be a museum in itself. The ceiling soars many stories above me, and in the vast space is suspended what I can only call an enormous art sculpture that resembles the electric pulses of a brain—except on a massive scale, extending all the way from the ceiling down to a few feet above the floor. Hundreds of lines of light connect colorful orbs, and as I watch, the lines flash and fade, glow and darken. It’s hypnotizing.

Other displays are encased behind glass boxes—human-like machines with metal limbs and legs, structures made of thousands of cylinders and circles all moving in a rhythmic pattern, curtains of light that look like a neon waterfall.

For a moment, I forget myself and wander from display to display, awed by the eerie beauty of it. I stop at a large timeline projected against the entirety of one wall. It shows the origins of the institute, old black-and-white photos progressing until the timeline ends on a modern-day image of the current building. Then everything shifts, the photos expanding so that they fill the wall, details printed over each image in white letters before scrolling to the next.

Headlines appear filled with praise for the institute—a center devoted to giving its clients cutting-edge technology, to conducting experiments decades ahead of their time, to the constant advancement of science.

The muffled sound of some distant sob cuts through my thoughts. I crouch against the wall on instinct, pushing myself deeper into the shadows. The cry has come from somewhere farther down one of the halls. Something about it seems familiar.

I wait. When I don’t hear anything else, I leave behind the main atrium and hurry down the hall closest to me.

It’s too dark in here to see the ceiling now, although the sound of my footsteps tells me how high the space is. Two thin purple neon lines highlight the edges of the floor. Several long minutes drag on, occasional sounds and voices ringing out. Somewhere ahead of me comes another muffled thud, then voices I don’t recognize.

The hall ends abruptly, leading into another enormous space—this time with several brightly lit rooms covered on all sides with thick glass walls.

Inside one room is Zero.

I frown. No, it’s not Zero—just something that looks like him, a black metal suit, tall and lean, its head and body completely encased in armor. A robot? Standing outside the glass room is Zero himself, deep in conversation with Taylor. She has several screens hovering in front of her, all of them only blank white, from my view. As Zero talks, she pushes her glasses up on her nose and types onto a screen in midair. Her shoulders look fragile in their hunched position.

Zero steps away from Taylor toward the glass. She nods at him. And, as I look on, he steps right through the glass wall and into the room with his armor.

I blink. He’s not here in person—he’s a virtual simulation. Then where is he?

Zero walks around the robot version of himself, inspecting it carefully. A loud beep sounds out from the glass room—and suddenly, the robot moves. Zero holds out his hand; the robot moves its limb in the exact same motion. Zero turns his head; the robot turns its head, too. Taylor pushes the door open and joins him in the room. She tosses a metal object at the robot, and Zero’s hand whips out. The robot does the exact same gesture, catching the object in a perfect grip.

I gape. Whatever this robot is for, it’s entirely hooked up to Zero’s mind, with a level of accuracy that frightens me.

The muffled sob I’d heard earlier now comes to me again. This time, I turn to see Jax emerge from the shadows of another hall at the other end of the space, shoving a figure forward until they’re both standing before the glass room. As Taylor and Zero step out, Jax forces the figure onto his knees.

In an instant, I forget all about the robot. I forget about Zero’s virtual self controlling the robot with his mind, and Taylor peering at her screens through her glasses. All that matters is the crouched, trembling figure, his skin washed white from the lights, his hair hanging in sweaty strings, his mouth gagged with a cloth.

Tremaine.

Jax’s words drift to me, her voice echoing in the space. “Found him messing with the security cams,” she says. “He tried making a run for the panic room when he realized I was on to him. Somehow, he knew the panic room’s system is off the main grid.”

Zero folds his hands behind his back and observes Tremaine’s bowed figure. “Sounds like someone has been studying the institute’s blueprints,” he replies.

“Sounds like someone was laying a path out for someone else,” Jax adds. “He’s not here alone.”

Tremaine shakes his head vigorously. His cheeks gleam wet under the light.

I can’t swallow. Any sound around me has now faded completely away behind the roar of blood in my ears, and the edges of my vision blur. No wonder Tremaine hadn’t responded to any of my messages tonight. He came here after all—and they’d known, maybe had even been waiting for him.

Taylor’s words rush back at me. And is that all you did tonight? I’m trying to warn you. I half expect her to step in and help him out, protect him from Jax and Zero. But she stays where she stands, screens still hovering around her.

They must have found out Tremaine was the one behind the hack into the institute’s files, that he had passed along the information—maybe even that he’d given it to me. How did they find out?

Through me. Maybe they were spying on our conversations; they’ve hacked into my accounts. Or they might have traced something Tremaine accidentally left behind.

Suddenly I feel a tidal wave of nausea—it’s the same feeling I have when I know danger is creeping forward, and all I want to do is push everyone else away from me so it can’t hook into any of them.

Tremaine has turned his face up to Zero now. Even in his terror, I can see the recognition registering on him—he’s never met Zero before, but he knows who he is. Jax leans down and removes Tremaine’s gag. Zero asks him something, but Tremaine’s lips don’t move to respond. All he does is stay silent. Jax’s shoulders shift as she sighs. Zero takes a step forward, but Jax shakes her head and holds a hand up.

Let me, she seems to be saying.

She takes her hands off Tremaine’s shoulder and stands back. The terror in me reaches a fever pitch. Everything around me seems to fade away as Jax pulls her gun from her holster and pulls it back with a click.

This should be the part when I scream something out, where one word from me makes everyone stop and look in my direction.

But instead, I can’t utter a sound. Jax points the gun straight down at Tremaine’s forehead. She fires a single shot.

Tremaine’s body jerks. He crumples to the floor.

My hands clamp over my mouth to keep me from letting out a cry. The shot rings in my ears.

The kill I’d once seen Jax make now comes back to me in a wave, and I double over, hunching against the wall as I try to brace myself against the onslaught of the memory.

We believe that there are too many people in the world who go unpunished for committing terrible crimes.

Those were Taylor’s words that had ultimately persuaded me to join the Blackcoats. She had told me they fought for causes they believed in. Their actions were justified because she—they all—feared what Hideo was capable of.

But in a single moment, every positive thing I ever thought about the Blackcoats, every word they’d plied me with, vanishes. Tremaine was alive just a second ago and now he’s dead, and it’s because of me.

Breathe.

Breathe.

But I can’t think straight. I can’t function in this moment except to crouch like some kind of coward, trembling uncontrollably against the wall. The glass room in front of me blurs and straightens. I think I see Taylor stepping back as two guards drag the body away, another lingers behind to clean up the floor. Zero leans toward Jax to speak in a low voice, while Taylor tucks something into the hands of the other guards. No one looks concerned. It suddenly occurs to me that the guards here were paid to wait around and bring Tremaine’s body outside, so that they could drive it off somewhere. They were prepared to execute him.

My panic is cutting my breath short. I feel faint. The edges of my view are darkening, fading out, and I fight against it, the logical part of my mind telling me that if I collapse now, here, they’ll find me. And if they know I’ve seen all this, they won’t hesitate to do the exact same thing to me that they just did to Tremaine.

Jax looks bored—exasperated with that person who took up her time—she hadn’t even looked back at Tremaine’s body, which she’d left on the floor. How many has she killed this way?

The Blackcoats are murderers. Tremaine had warned me to stay away from them from the start—he’d only been here because he was looking out for me. And I’d gone ahead anyway. Now he’s dead. What if the Blackcoats are already out looking for me, having learned the connection between Tremaine and my work?

What have I done?

I can’t do this. I can’t stay here. I close my eyes and count, forcing myself to focus on the train of numbers in my head until they’re all I see. Hideo needs to know this. But what do I tell him? I don’t even understand everything I just saw. What is that robot that Zero had been commanding? And if he’s not here in person, where is he?

Get up, Emi.

I whisper the words over and over, until finally I unfreeze myself. I push my body off from the wall, rise from my crouch, and stumble back the way I came. Feverishly, I pull up my menus and set my maps for the hotel. I make my way far enough so that I’ve left the horrible room behind me and have reentered the soaring main lobby of the complex.
