Mara reached the door first. Her palm went flat against the polished wood—warm, almost, like something living—and she wrapped her fingers around the brass handle and pulled. It didn't move. Not the give of a stiff latch, not the grind of old hardware. Nothing. The handle sat in her grip like it had been welded there.

"Come on," she muttered, and tried again, harder, dropping her shoulder into it. The door didn't rattle. Didn't flex. The polished wood took her weight and gave back none of it, and somewhere under her ribs the cop in her—the one who'd kicked in a hundred doors, who'd known the exact sound a lock makes when it surrenders—went very quiet and very still.

"It's locked," she said.

"Locked?" Elle was already moving, the heels of her boots clipping across the marble. "It can't be locked. He just walked out of it."

"He walked out of it," Mara agreed, "which means it locks from the outside." She stepped back and looked at the door properly for the first time—the full slab of it, taller than any door had a right to be, the seams so tight she couldn't have slid a fingernail between them. There was no keyhole on this side. No deadbolt. No keypad. Just wood and brass and the two of them standing in front of it like idiots.

"Okay," Elle said, and pushed her hair back with both hands, the way she did before she started dismantling a witness. "Okay. Frames. There's always a frame." She went sideways along the wall, fingers skimming the woodwork, nails catching on the screw heads of the hinges, following the trim up and around and over. Mara watched her do it and felt the first cold thread of something she didn't want to name slide down the back of her neck.

Because the hinges were on this side. Hinges on the inside meant the door opened inward, meant it was built to keep something in, and the screws were painted over. Not stripped. Painted. Deliberately, carefully, the way you'd paint over a thing you never intended anyone to touch again.

"Mara." Mila's voice, behind them, thin in a way it never was on camera. "Mara, do you have a signal?"

Mara pulled her phone out of her jacket without looking away from the door. No bars. The little icon sat there in the corner, empty, mocking. She'd had two bars on the private road. She'd watched them flicker down to one and then to nothing as they'd come through the gate, and she'd told herself it was the trees, the elevation, the usual dead zone you got out past the county line. She hadn't told herself anything about what it meant that the last signal died exactly at the gate.

"No," she said.

"Mine either. Elle?"

Elle stopped her hands on the trim. She didn't answer right away, and that—more than the locked door, more than the dead phone—was what made Mara's stomach turn over. Elle Shelby not answering was like a clock not ticking.

"Elle."

"No signal." Elle turned around. Her face was doing the thing it did right before she lost a case—all the color pulled back behind her eyes, everything locked down, nothing showing. "And no latch, no keypad, no intercom, no bell. This isn't a front door. This is the lid of a box."

The room was very quiet. The fire had burned down to the low blue flicker of coals, and the bread on the table had gone cold an hour ago, and somewhere deeper in the house a clock was ticking—she'd heard it the whole time they'd been sitting here and hadn't once thought about what it meant that a house this size had exactly one clock and it was loud enough to hear from three rooms away. Like a heartbeat. Like something counting.

"Okay," Mara said, and heard her own voice come out flat and level, the voice she used on scene. She turned her back on the door and looked at the room the way she should have looked at it forty minutes ago. Windows. There were windows—two of them, tall, dark, the rain sheeting down the glass in long silver threads. She crossed to the nearest one and put her hand on the frame, and it was the same story: no sash, no latch, no crank. Sealed. The glass was thick, thicker than any residential glazing she'd ever seen, and when she rapped it with her knuckle it made a sound like a knuckle on a bank vault.

And in the dark glass, over her own reflection—her ponytail, her jacket, the set of her jaw—she saw him.

Adrian. Standing out on the gravel, ten feet back from the window, arms loose at his sides, the rain coming down around him and not touching him, or touching him and him not caring, she couldn't tell which. He wasn't looking at the house. He was looking at her. At her specifically, at the exact pane of glass her palm was pressed against, and when their eyes met through the wet black glass he didn't move, didn't wave, didn't smile. Just watched. The way you watch a thing you've already decided about.

"Mara." Mila again, closer now, and when Mara turned, Mila was right behind her with her arms crossed tight over her chest and her teeth caught in her lower lip. "He's out there. He's just—standing there."

"I see him."

"Do we—should we knock? Should we—"

"No." Mara cut her off, and it came out harder than she meant, and she saw Mila flinch, and she made herself breathe. "Sorry. No. We don't knock. We don't wave. We don't do anything he can read." She stepped away from the window, and the skin of her palm was cold where the glass had been, and she rubbed it against her thigh without thinking. "He wants us to do something. That's the whole point of standing there. So we don't."

"He said he'd have the car brought up," Elle said. "He said his men were bringing the car up. We watched them go. We heard the truck."

"We heard a truck."

Elle's mouth closed. She looked at the window, at the shape still standing out there in the rain, and then she looked at Mara, and for one second—just one—the mask slipped and Mara saw it underneath, the thing Elle never let anyone see: not fear, exactly. Something worse. The look of a woman who had spent her whole life being the smartest person in the room and had just realized she didn't know what room she was in.

"He cut the tires," Elle said quietly. "Didn't he."

"I don't know that yet."

"You know."

"I know it doesn't matter right now." Mara turned in a slow circle, taking the room in again with the door at her back—the fire, the long table, the bread, the two glasses, the third glass Adrian had poured and never drunk. The chandelier overhead, twenty bulbs in a brass web, all of them lit, all of them steady. The vents in the ceiling, four of them, dark slits set flush into the plaster. The hall behind them, running off into the house, dark past the first doorway.

"There's a back door," she said. "There's always a back door. Kitchens have doors. Service entrances. This house has staff, staff have to come and go, there's a door somewhere that opens from the inside."

"And if there isn't?"

"Then we break a window."

Elle looked at the glass and said nothing, and Mara understood the silence perfectly, because she'd felt the same thing under her knuckle. That wasn't glass you broke. That was glass you'd need a car to break, and their car was allegedly being brought up, and the man who'd allegedly sent for it was standing in the rain watching them through it.

Mila made a small sound. Not a word. Mara turned and found her standing very still in the middle of the room with her head tilted, her eyes narrowed, her mouth slightly open, listening—and that was when Mara heard it too. A hum. Low, subsonic, coming from everywhere and nowhere, the sound a house makes when something in its walls is running.

"What is that," Mila said.

"Air handler," Mara said. "Furnace. Something in the basement."

"It wasn't doing that before."

Mara opened her mouth to say it was nothing, it was a big house, big houses made noise—and the chandelier flickered. Once. Twice. The twenty bulbs stuttered in their brass web and the shadows jumped up the walls and came back down, and in the half-second of dimness Mara saw the room as a stranger would see it: a locked box with a fire in it and three women standing in the middle, and a man in the rain outside who had never once stopped watching.

Then the lights came back.

"Okay," Mara said, and her voice was very steady, and she was already moving toward the hall. "Okay. We find the back door. Now. Elle, take Mila, check the windows on that side. I'll take the hall. We stay in sight of each other. We do not split up, we do not go upstairs, and if either of you sees anything that looks like a phone, a radio, a panic button, a servant's bell—you yell. Clear?"

"Clear," Elle said.

"Mila."

"Clear." Mila's voice wobbled but it held. She pulled her cardigan tighter around herself, the soft pink of it absurd in this room, and she nodded, once, fast, the way she nodded at the end of a forecast. "Clear."

Mara went into the hall.

It ran straight back into the house, thirty feet of dark marble, and the further she went the darker it got, the light from the sitting room fading behind her until the only thing she could see was the pale rectangle of a doorway at the far end, gray with reflected rain-light. She walked toward it with her hand skimming the wall—paper, then paneling, then something that gave under her fingers, a recess, a switch—and she stopped and felt for it and found it, a bank of them, four toggles in a brass plate, and she flipped the first one.

Nothing.

The second. Nothing. The third. Somewhere behind her, in the sitting room, one of the lamps went out with a soft click, and Mila said "hey—" and Mara froze with her fingers on the fourth toggle.

She flipped it back. The lamp came on. She flipped it again. Off.

"Okay," she said, out loud, to no one. "Okay." Someone had wired the switches wrong, or someone had wired them right, and either way it told her something she didn't like: that the lights in this house answered to a logic she didn't have, and that somewhere in this house was a room where the lights did what they were told.

She left the switches alone and kept walking.

The far doorway opened into a kitchen—she smelled it before she saw it, the cold clean smell of a room that got scrubbed every day and used maybe twice a month. Stainless steel, a long island, a rack of copper pans hanging over it that threw back what little light there was. And there, at the back of the kitchen, past the island, a door. A real one. Wooden, old, with a bar handle and a deadbolt and a little window in the top half, and the window was black with night and rain, and Mara's heart came up into her throat because it was the first thing in this house that had looked like a way out.

She crossed the kitchen fast. Her boots rang off the tile and she didn't care. She got her hand on the deadbolt and turned it—it moved, it moved, it slid back with a real mechanical chunk—and then she got her hand on the bar handle and pushed, and the door opened six inches into a rush of cold wet air and rain, and Mara closed her eyes for half a second in pure animal relief.

Then she opened them and looked properly.

The door opened onto a concrete stoop. Beyond the stoop, four feet of gravel, and beyond the gravel, a fence. Not a garden fence. A wall—twelve feet of it, concrete and steel, with a row of spikes along the top that caught the rain and turned it to silver, running off into the dark in both directions as far as she could see. The same wall she'd seen from the road. The same wall she'd thought was the property line.

It wasn't the property line. It was the fence around the yard, and the yard was the box, and the box had a lid, and she was standing in the kitchen of it with her hand on an open door.

Somewhere behind her, in the house, Mila screamed.

Mara was moving before she'd finished hearing it. She left the door open—left it wide, let the rain come in, let the cold come in, let the whole night come in—and ran back through the kitchen and down the dark hall with her boots sliding on the marble, and the sitting room swam up out of the dark ahead of her, and she saw Elle first, Elle with her arms out and her body between Mila and the window, and Mila behind her with both hands over her mouth, and the window—

The window was black. No rain-light, no gravel, no man. Just black, flat and total, like a shutter had come down over the glass from the outside, and as Mara watched, the black rippled, once, the way water ripples, and she understood that it wasn't a shutter and it wasn't black. It was a face. Adrian's face, pressed to the glass, watching them through it with his hands cupped around his eyes, and he was smiling.

Mila screamed again, muffled through her fingers.

"He's—he's right there, he's—"

"I see him." Mara got her hand on Mila's shoulder and pulled her back, put herself between the window and both of them, and she could feel Mila shaking through the cardigan, fine and fast, like a phone on vibrate. "Elle. The kitchen. There's a door, it opens, it's real. Go."

"What about—"

"Go. Take her. I'm right behind you."

Elle didn't argue. That was the thing about Elle—when it mattered she didn't argue, she moved, and she had Mila by the wrist and was hauling her toward the hall before Mara had finished the sentence. Mara turned back to the window.

Adrian hadn't moved. His face hung in the black glass like something pressed flat under ice, still smiling, and Mara walked up to it—close, close enough that her breath fogged the pane, close enough that if the glass hadn't been there she could have touched him—and she looked him dead in the eye through the wet black and she mouthed two words, slow and clear, so there'd be no mistaking them.

Fuck. You.

Adrian's smile didn't change. But his eyes did—something moved in them, something that wasn't anger and wasn't amusement, something hungrier than either—and he lifted one hand, slowly, and laid it flat against the glass on his side, palm to palm with where hers had been ten minutes ago.

The chandelier flickered.

Once. Twice. And then the whole house went black—not the brown-out flicker of a failing bulb but a total, absolute dark, the dark of a basement, the dark of a closed eye—and Mara's hand came up automatically, feeling for the wall, feeling for anything, and found nothing, and in the sudden blindness she heard it: a soft hiss, low and steady, coming down out of the dark above her. From the vents. All four of them, hissing at once, a sweet chemical smell threading into the room underneath it, something like burnt sugar and something like the dentist's office and something like nothing she'd ever smelled before.

Her knees went.

Not buckled. Went—the whole structure of her, hip to knee to ankle, dissolving out from under her like the floor had turned to water, and she caught the edge of the long table with one hand and the tablecloth came with her, the glasses, the bread, all of it, and she was on the floor before she understood she'd fallen, her cheek against the cold marble, her ponytail loose and wet across her face, and the hissing went on and on above her, patient, unhurried, like something that had all the time in the world.

Down the hall, she heard Elle's voice, thick and far away: "Mara—"

And then nothing.

Mara lay on the marble with the taste of burnt sugar on her tongue and the dark pressed against her eyes, and the last thing she thought, before the dark took the rest, was that the door to the kitchen was still open. She'd left it open. The rain was coming in. And somewhere out in that rain, on the other side of the glass, a man was standing with his palm pressed flat to the window, waiting for her to finish falling.
