Room Tone

"The air," said Ryder Okafor, "is mostly nothing."

He said it with a certain bleak pride, as a man might say it of the desert. We were in the sound room on the third floor, a narrow windowless closet that smelled of dust and warm electronics, with foam panels on the walls and a mixing desk the size of a billiard table. It had been built, I gathered, for the purpose of cleaning up recordings of wiretaps and 911 calls; there were shelves of cables labeled in a small cramped hand, a rack of equipment with a hundred tiny green lights, and a pair of enormous black speakers on stands, like the heads of two patient animals.

Ryder sat in the center of it all, with headphones round his neck, like a pilot.

"I took the voice out," he said. "As requested. It wasn't hard. He'd put it through a vocoder and a pitch-shifter, so the frequencies were all in a band I could cut cleanly. Most of what's left is just the noise floor." He pointed at the screen. "That's what you're hearing. The sound of the room with nobody in it. It's called room tone."

"Play it."

He did.

A hiss filled the room. It was soft, even, and a little rough, like rain on a distant roof. It rose and fell in tiny currents. Underneath it, very low, was a steady droning hum, as of a refrigerator in the next room. I listened for a full minute. Vera, who had come in behind us, listened too, with her arms folded and her head tilted a few degrees, like a woman at a concert she had not wished to attend.

"I don't hear anything," she said.

"That's right," said Ryder. "Because it's covered. Everything in the world's covered by that hum." He tapped the screen. "Sixty cycles a second. It's the mains. It's the electricity in the wall. You get it in every recording ever made in America. It's like a rug over a floor."

"Take the rug up," I said.

…

He took it up.

He did it with a delicacy that was a joy to watch. A twist of a knob. A sliding of a fader. On the screen a thin spike at the bottom of the display shrank, and shivered, and flattened, and was gone, and as it went the hum fell away from the sound like a veil. The hiss was still there. But it had changed. It had become spacious. I could hear that it was not a flat gray roar, but a thing with shape and depth, with edges, and I leaned forward without knowing it.

"Now the middle," I said. "Bring up the middle. As high as it will go."

"Four hundred percent?"

"If it will stand it."

He grinned. "It'll stand it for about a minute."

He pushed the fader up.

The noise bloomed. It swelled and sharpened, and little details began to stand out of it like islands from a falling tide. A scrape. A sigh. A small dry click like a mouse in a wall. And then, behind them all, a long thin steady whistling, rising and falling, with a pitch that wavered a little.

"Wind," said Leo.

He had come in so quietly that I had not noticed. He stood in the doorway with his hand on the frame and his face tilted toward the speakers.

"That's wind. That's a lot of wind. Coming through a gap."

"A crack, I'd say," said Ryder. "Or a louvered opening. It's got a flutter on it." He moved the fader a hair. "There's a draft going in and out, and it's pretty high up. I'd say forty or fifty feet. You wouldn't get a pitch that clean at ground level. There's too much stuff in the way."

"A tower?"

"Could be."

I held up my hand. "Quiet."

They were quiet.

It came very softly, at first. It was hardly a sound at all. A kind of tremor in the dark, a vibration so slight that it might have been a flaw in the speaker, or the beating of my own blood. It came again. A little louder. And then, with a deep, dull, swinging, ponderous rhythm that I could feel in the soles of my feet, it came a third time, and I heard it plainly.

A bell.

…

It was a low bell, and a big one, and it was not right.

I heard that at once. I could not have said how. There is a quality in a good bell, an ease, a roundness, as if the sound were being poured out of it from a pitcher. This sound did not pour. It struck, and it rang, and for a moment it was beautiful, a full dark golden tone that seemed to fill the room; and then, at the end, instead of dying away smoothly, it fractured. It broke into pieces. The tail of it splintered into a spray of harsh, thin, angry overtones, like a plate dropped on stone.

"Jesus," said Vera.

"Play it again."

Ryder played it again. We heard the wind, and the long dark swing, and the golden ring, and the dreadful shattering at its end.

"A temple bell?" said Leo. "One of those, uh, Buddhist things? Chinese? There's a place on Race Street with—"

"No," I said.

"How d'you know?"

"Because I have stood under a good many temple bells in my time, Captain, and they all sound the same." I closed my eyes. "They are cast in a mixture of bronze that is very rich in tin. The sound they make is long, and warm, and almost human. It hums for a full minute, and when it dies, it dies like a breath. That is a wonderful sound. This is not that sound."

"Then what?"

"Ryder, can you put it on a spectrum?"

He could. In a moment the screen was filled with a spray of vertical lines, red and yellow and green, rising like the pipes of an organ. He studied them for some time, frowning. He highlighted a band. He zoomed in. He muttered something under his breath about partials and minor thirds.

"It's Western," he said at last. "The structure's all wrong for Asian bronze. It's got a strong minor third in the overtones. That's typical for a cast church bell, like something from a European foundry. English, maybe. Or Dutch. And look at the decay." He pointed. "That's not natural. A good bell damps down in a nice smooth curve. This has a hard cutoff here, and then a spray of high stuff. That's a crack."

"A crack in the bell," I said.

"A big one. Probably running up from the lip." He turned. "It's been rung that way for years. The metal's rubbed along the break. It hasn't broken all the way through, or it wouldn't ring at all. But it's close."

"Like the Liberty Bell," said Leo, with a sour grin.

"The Liberty Bell was recast," said Ryder, without turning round. "Twice."

"Everyone's a critic."

…

"It isn't ringing," I said.

They both looked at me.

"Listen." I leaned toward the speaker. "It isn't being rung. Do you hear the interval? It's a single stroke, then a gap of forty seconds, then another. There's no rhythm. No hour. If it were a clock, it would strike regularly. If it were a sexton, he would toll for a purpose. No. It is being touched by the wind. The clapper is hanging loose, and the gusts are swinging it against the side, once in a long while, when the pressure rises." I opened my eyes. "That bell has not been used in years. It is in a tower that has no keeper. And it is in a place with a good deal of weather."

"An abandoned church," said Vera.

It was the first thing she had volunteered. I turned, and found that she had come round the desk and was standing at my shoulder, looking at the screen with a hungry, narrowed expression. Her thumb was not pressed against her finger.

"A Catholic one," she said. "Western bells. A cast bell with a crack in it. It's an old parish. The Archdiocese closed forty in the last twenty years. They stripped the pews and left the towers."

"Exactly."

"But that's—" She stopped. "That's hundreds of places."

"Not quite hundreds," I said. "Mr. Okafor, how many square feet would he need?"

"For what?"

"For the thing he was doing. For the equipment. He's a man who builds machines for killing people with their own minds. He needs a workshop. He needs a place to keep what he's made. He needs a place to send a message from, and he needs it to be safe from the network, and he needs to be able to run a good deal of electrical equipment without anyone noticing." I turned to the map. "So. A building with a tower. A tower with a bell. A building he can reach without being seen, with a power supply he can hide a load on. Not an active church; there'd be a sexton, a priest, a janitor. Not one in a built-up neighborhood, where a light in a window would draw attention. He wants somewhere large, empty, and forgotten."

"Which means," said Leo slowly, "a church with a scrap yard next door."

…

It took them three hours.

I sat in a corner of the briefing room, with a mug of cold tea and my feet on a chair, and watched Leo Maddox perform a kind of ancient and wonderful magic. He had a map of the city on the wall, a huge ugly municipal thing with red and green zones, and he stood in front of it with a marker and a phone, and made, in a voice like a man calling a card game, a series of cheerful demands.

"Give me every parish the Archdiocese closed since 'oh-five. Yeah. Give me the address and the year. Now cross it with the demolition schedule. Anything inside a clearance zone. Okay. Now the power. Anyone get a shutoff notice from the utility in the last two years? Anyone with a meter pulled? Good. Now the load. I want any of those that are still pulling more than five kilowatts."

The map began to fill.

Red dots appeared, one by one, like a rash. A cluster in Kensington. A string along the river. A handful in the west, and one lonely one on the far edge of the northeast. Each was an old bruise on the face of the city. Each was a place where a congregation had gone and a building had stayed.

Dots turned off as the filters bit. A church in South Philly had been under four feet of water since last Tuesday; Ryder had a photograph of the nave with a floating pew. Another, in the east, was a clapboard chapel without a belfry. A third had been sold to a developer and was half demolished.

At a quarter to one the screen showed three.

"The south one's flooded," said Leo. "Can't be. You couldn't run a toaster. The east one's wood. No tower. That leaves—"

"Here," said Vera.

She had put her finger on the map. At the top of the city, in the cold gray rim of the industrial north, beside a rust-colored sprawl labeled DELANCEY SALVAGE & SCRAP, sat the third red dot. It was almost invisible. It was a small, neat, dark square, with a little cross drawn in it.

"St. Aurelian's," she read. "Closed two years ago. Parish of eleven hundred. Fell apart when the pastor died." She tapped. "There's a scrap yard on the east side. It's still got a feeder from the old utility grid, a big commercial one. If you wanted a draw nobody'd notice—"

"You'd tap it," I said.

Nobody spoke.

Outside the window the rain had begun again. It came down slow and straight and gray, streaking the glass. Leo put down his marker. Ryder shut his laptop. Vera lowered her hand, and I saw that it was shaking very slightly.

"That's where he keeps his servers," I said.

I stood. I put on my coat. I buttoned my waistcoat, one button at a time, from the bottom to the top, and found that my fingers were quite steady.
