Thomas Reid had been awake for hours. It was past two in the morning, and the trailer smelled of stale tobacco and the sour, metallic tang of the Mississippi River coming through the cracked window. He sat in his recliner, the kind with the cup holder in the arm that had fallen off years ago, and listened to the static.

The radio sat on a crate beside him. It was an old thing, a Sony he'd pulled from a dumpster behind a hardware store in Quincy. He'd opened it up, cleaned the contacts, replaced three capacitors with parts from a TV he'd gutted. The casing was held together with duct tape and a zip tie. When he turned the dial, the display flickered between numbers like it was unsure of itself.

Thomas liked the static best. It was soft. It was the sound of nothing happening, which was the same as everything happening, if you thought about it long enough. He'd learned that over fifty-five years. Not that he thought about it much. He didn't have much time for that kind of thing anymore.

The signal came between stations. He couldn't have told you the frequencies. He barely understood frequencies. What he knew was that the static shifted, the way wind moves through dry corn, and underneath it was something else. A rhythm. Not mathematical. Not like the examples he'd seen as a kid in science books. Something more like tapping. Tap. Tap. Tap. Like someone standing on the other side of a door.

Thomas sat very still. He held his breath. The tapping came again. He pressed the side of his head with the earpiece and closed his eyes. It was faint. It was almost nothing. But it was there. He knew it was there because he'd spent thirty years listening to things that were almost nothing.

He took off the earpiece and set it on his knee. He looked out the window at the river. It was black and wide and moved slow, the way it always did, like it had somewhere to be but no reason to rush.

Thomas turned back to the radio. He turned the dial half a millimeter to the left. The tapping came back. Clearer this time. He could feel it in his teeth.

He sat there for another hour, maybe two. He didn't know. He didn't keep track of time the way other people did. When the tapping stopped, it just stopped, like someone had gone upstairs and closed a door. The static filled the space the way water fills a hole in the ground.

Thomas turned off the radio. He didn't want to lose the sound of it, but he also didn't want it to stop. He sat in the dark and listened to the house settle around him. The pipes groaned. The trailer shifted on its blocks. Outside, a dog barked once, then stopped.

Thomas Reid went to the kitchen and made coffee. He drank it standing up at the sink and looked at the river. It was still there.

---

He told nobody that first night. There was nobody to tell, mostly. His nearest neighbor was a mile down the road, a man named Dale who kept a flock of chickens and didn't talk to anyone. Thomas had talked to Dale once, about a fence line they both thought belonged to the other person. It hadn't gone well.

So Thomas sat in his trailer and drank coffee and listened to the static and tried to figure out what he'd heard. He wasn't a smart man. He'd never finished high school, not because he was stupid but because he'd gotten a job at a plant in East St. Louis when he was sixteen and the job had been good and the money had been good and then the plant had closed in '97 and the money had stopped.

He knew about radios. He'd fixed them his whole life. Not as a profession—he'd run a repair shop for a few years, out of a strip mall next to a nail salon. The shop had failed because nobody fixed anything anymore. They just bought new. That was the way of the world. If a refrigerator broke, you replaced it. If a marriage broke, you divorced. If a person broke, you pretended not to notice.

But he knew radios. And he knew that what he'd heard on that static was not interference. Not from a plane or a ship or a cell tower. It was too regular. Too deliberate. It had a shape to it, like a hand shaping itself around something invisible and holding it there.

For a week, he listened. He came back to the radio every night. He sat in his recliner with the earpiece pressed to his ear, sometimes asleep, sometimes wide awake, and he listened. The tapping came back every few nights, always between stations, always fading before he could be sure of anything.

Then he called his daughter.

He hadn't called her in two years. She lived in Chicago, or somewhere around there. She had a husband named Kevin, or maybe it was Ken. He wasn't sure. He had a grandchild he'd never seen. A boy, he thought. Or maybe a girl. He'd been at the hospital once, ten years ago, holding her when she was born. He'd held her for five minutes and then she'd taken her back and said, "You should go, Dad."

He called her from a payphone at a gas station off Route 66. He'd driven there because he didn't have a cell, and he hadn't bought a phone in twelve years. He dialed the number he'd written on a napkin and stood on the concrete island between pumps, listening to the ring.

She answered on the fourth try. Her voice was sharp. "Hello?"

"It's me," he said.

There was a pause. He could hear a television in the background. A news program, maybe, or a game show. Something bright and loud.

"Dad." She said his name like it was a thing she'd found on the floor and didn't want to touch.

"I need to tell you something."

"Is everything okay?"

"Yes. No. I mean—" He looked at the gas pump. It was counting dollars in three-dollar increments. "I heard something, Emily. On the radio. Last night."

"What did you hear?"

"A signal. It was— it was like someone calling. Not in words. Not exactly. But like someone on the other side of a wall, tapping to let you know they were there."

His daughter was quiet for a moment. He could hear her breathing. He could hear the television. He could hear a baby crying in the distance.

"Dad," she said. "What are you saying?"

"I'm saying I think it was— I'm saying someone was calling. From somewhere. And I think—"

"From where?"

"I don't know. That's the thing. I don't know where."

Another pause. Longer this time. He could hear her talking to someone. A whisper. Then back to the phone.

"Dad, I have to go. Kevin needs me with the kid."

"Emily, wait—"

"I'll call you sometime, okay? Take care of yourself."

The line went dead. He stood there with the receiver in his hand and watched the gas pump finish its cycle. A truck pulled in behind him. The driver got out and went to the store. Thomas put the phone back and walked to his truck without looking at it.

He drove home slow. The road was dark and straight, and the trees on either side were cottonwoods, mostly dead, their white bark peeling like old paint. He thought about his daughter. He thought about the sound of the line going dead, which was the same sound as every other time someone had stopped listening to him.

---

The next night he went to the bar. There was one in town, called the Riverbend, out past the motels that were all empty most of the year. The bartender was a guy named Rick. He'd been a bartender for as long as Thomas could remember. He had the same gray t-shirt and the same flat eyes and the same way of looking at you like you were a number on a piece of paper.

Thomas sat at the bar and ordered a beer. Rick put it in front of him without looking. Thomas drank half of it and then said, "Hey Rick."

Rick looked at him. "Thomas. What can I get you?"

"Nothing else. I just—I heard something the other night. On the radio."

"Good for you."

"It was a signal. Not from here. Not from this country, I mean. From— I don't know. From space, maybe."

Rick wiped the bar. He'd been wiping the same spot for a minute. "Space," he said.

"That's what I think."

Rick laughed. It was a short, dry sound. "Space, huh? Well, I guess that explains the price of beer."

Thomas smiled. He wasn't sure why. Rick was smiling too, but it wasn't a real smile. It was the kind of smile you give someone who's telling a joke you're supposed to find funny.

"You serious?" Rick asked.

"No," Thomas said. Then, after a moment: "Yes. I mean, I don't know. I heard something. It sounded like—"

"Like what?"

"Like someone asking for help."

Rick set down the rag. He looked at Thomas with something like pity, which was worse than the laughing. "Hey, Thomas. We all hear things, right? Static. You know how it is."

"It wasn't static."

"Could've been. You know how old radios are. They pick up everything. Planets. Stars. I don't know. The sun."

"The sun doesn't tap."

Rick shrugged. "Maybe it does. Who knows."

They were quiet for a while. Thomas drank his beer. Rick wiped the bar. A couple at the end of the counter were laughing at something on the TV mounted in the corner. It was a football game. Neither of them was watching it.

"Thanks, Rick," Thomas said when he stood up.

"Anytime, buddy."

He walked home under a sky that was full of stars and that he had never once thought of as a place where someone could be tapping on a radio, asking to come home.

He built the transmitter in his garage. Not really a garage—a shed out back, the roof sagging in the middle, the floor covered in sawdust and old motor oil. He had parts everywhere. Capacitors. Resistors. Wires stripped from old appliances. A car battery he'd borrowed from Dale and never returned.

He worked at night, after the sun went down and the trailer filled with shadows. He soldered connections with a gun he'd bought at a garage sale for fifty cents. He twisted wires together and wrapped them in electrical tape. He didn't know what he was doing, not really. He'd seen a diagram once, in a magazine, something about transmitting antennas and frequency matching. He'd cut the picture out and kept it in a drawer.

When he was done, the thing looked like a pile of junk on a workbench. It was bigger than the radio, maybe two feet tall, with an antenna made from a coat hanger and a copper wire he'd stolen from a hardware store. It hummed when he plugged it in, a low vibration that he felt in his hands.

He sat at the radio and pressed the transmit button. The static got louder. It was a different static, too. Sharper. More aggressive. Like it was talking back to him.

He pressed the button again. And again. He thought about the tapping. He thought about the rhythm. He tapped the button in the same pattern. Tap. Tap. Tap.

He did this for an hour. Maybe two. He didn't know. He sat in the shed, pressing a button, listening to the static, feeling the hum of the machine in his hands. He was thinking about his daughter. He was thinking about Rick. He was thinking about the river, moving slow and black and endless.

Then it came. The static shifted, the way wind moves through dry corn, and underneath it was the tapping. Tap. Tap. Tap.

Thomas stopped breathing. He pressed the button and said, into the microphone he'd wired in, "I hear you. I'm here."

The tapping changed. It slowed. It stopped. Then it started again, different, not the same pattern, something new, something that might have been a question.

Thomas pressed the button again. "I'm here," he said. "I hear you."

For a moment, the static cleared. Not completely. It never cleared completely. But underneath it was a sound he couldn't name. It wasn't a voice. It wasn't music. It was something else, something that made his chest ache the way a song can make your chest ache when you hear it in a car driving down a dark highway and you're alone and you don't care who knows it.

It lasted maybe ten seconds. Then it was gone. The static filled the space again, and the tapping stopped, and the transmitter hummed its low, steady note.

Thomas sat there for a long time. He held the button in his hand and didn't press it. He thought about the sound, whatever it was, and how it had felt like being heard for the first time in fifty-five years.

---

Morning came gray and thin. The kind of morning where the sun is there but it doesn't feel like much of anything. Thomas made coffee and stood at the sink and looked at the river. It was the same gray color as the sky. It was always the same gray color.

He walked back to the radio. It was still on, still humming, still picking up whatever it picked up. The static crackled softly in the dark of the shed. It sounded like nothing. It sounded like everything.

Thomas sat in his recliner and listened. He didn't turn the radio off.
