The rain in New York doesn't wash anything clean. It just makes the grime slicker, turns the sidewalks into mirrors that reflect the neon signs in long distorted streaks of red and blue and sickly yellow. Sammy Goldstein knew this. He had known it since he was a kid walking these streets, since the Army, since the restaurant on 47th Street that was supposed to be his fresh start and was instead just another place to serve coffee to people who didn't want to be found.

The restaurant was small, all chrome and red vinyl, with a jukebox in the corner that only played things Sammy didn't want to hear. It was past midnight on a Wednesday when the door opened and the man walked in, shaking rain from a coat that cost more than Sammy's car.

"Count Valenti," the man said, sitting at the counter without asking. "And I'll have black coffee. Black as the soul of a man who's seen too much."

Sammy poured the coffee. "You're from out of town."

"I'm from everywhere and nowhere," Valenti said, and took a sip. His eyes never left Sammy's face. "You were in the war. Pacific. You don't talk about it."

Sammy's hand froze on the pot. "What else don't I talk about?"

Valenti smiled. It was a warm smile, the kind that made you want to tell him everything. "That you came back because you couldn't come back. That the island you were stationed on still appears in your dreams. That you keep a rifle under your bed and check the lock on your door three times every night."

Sammy set the pot down hard. Coffee sloshed over the rim. "Who are you?"

"A friend," Valenti said. "And a messenger. There's someone in this city who would like to meet you. Someone important."

"Nobody important wants to meet me."

"Everyone is important to someone," Valenti said, and finished his coffee, and left a bill that was worth more than a week's tips, and disappeared into the rain.

He came back the next night. And the night after that. Each time, he knew something new about Sammy—where he had grown up, what his mother used to call him, the name of the friend who hadn't come home from the Pacific. Each time, he left more money. Each time, he mentioned the same name: The Family.

"They run this city," Valenti said on the seventh night, leaning close across the counter. "Not the politicians. Not the cops. Us. The ones who understand that power isn't about money. It's about knowledge. About knowing things before they happen. About knowing the things people try to forget."

Sammy should have thrown him out. Instead, he poured another coffee.

Weeks passed. Valenti became a fixture, and then a necessity, and then something Sammy couldn't imagine life without. He could predict the stock market, the weather, which customers would walk through the door and what they would order. He could make a broken radio play and a dead plant bloom. He was, Sammy began to understand, something other than human.

He didn't care. The city was cold and the restaurant was warm and Valenti made it feel like something, anything, other than what it was.

Then O'Malley walked in.

He was a big man with a face like a fist and a suit that had been fashionable in another decade. He sat at the counter, ordered black coffee, and looked at Sammy with eyes that had seen too many bodies and too many lies.

"You're hosting a夜族," O'Malley said.

Sammy didn't pretend to understand. "I host whoever walks in the door."

"Goldstein, I was born on this block. I know who Valenti is. Or what he is. His people call themselves the Nightborn. They've been around since before this city was a swamp. They feed on belief, Goldstein. On the faith people put in them. The more you believe in him, the stronger he gets. And the weaker you get."

Sammy laughed. It was a nervous laugh, the kind that sounds like glass breaking. "You're crazy."

"Maybe," O'Malley said. He pulled a folder from his coat and slid it across the counter. Inside were photographs—grainy, black and white, showing men who looked like Valenti in cities across the country, in different decades, always the same face, always the same coat. "I've been tracking his kind for thirty years. They move from town to town, build devotion, drain their hosts, and move on. When they're empty, the Nightborn leave and find someone new."

Sammy looked at the photographs and felt something cold settle in his stomach. "Why are you telling me this?"

"Because I'm old and tired and I can't do it anymore. And because tonight is the night he leaves. And I want you to be ready for what happens when he goes."

Sammy wanted to believe him. He wanted to throw O'Malley out and call Valenti and tell him a detective was spreading lies. But that night, when Valenti came in and sat down and smiled and said, "Sammy, I have something to show you," Sammy saw something in his eyes that he had missed before—a hunger, ancient and patient, that had nothing to do with coffee.

He showed Sammy things. Rooms beneath the city that shouldn't exist. Streets that led nowhere and everywhere. A place where time moved differently and the people who lived there were beautiful and terrible and utterly, completely alien.

Sammy believed him. He believed him with everything he had left.

And that was when The Curved One arrived.

He came in without opening the door. One moment the restaurant was empty except for Sammy and Valenti, and the next moment there was a third man sitting in the booth behind them, and Sammy hadn't heard a sound.

The Curved One was old, impossibly old, with a face that seemed to shift and fold like paper being creased and uncreased. He wore a dark suit and a hat, and his eyes were the colour of rain on asphalt.

"Julian," he said, and his voice was the sound of tires on wet pavement. "You have overstayed."

Valenti looked at him like a child caught stealing. "I was helping him."

"You were feeding him," The Curved One said. "There is a difference. And you are growing careless."

He turned to Sammy. "You will forget most of what you have seen. That is the way of things. But a piece will remain, like a stain that won't come out. That is also the way of things."

"Can he stay?" Sammy heard himself ask.

The Curved One looked at him for a long time. Then he smiled, and it was the saddest thing Sammy had ever seen. "No. But you can keep the coffee warm for him. That is all any of us can do."

They left together, into the rain, and Sammy stood in his empty restaurant and listened to the sound of their footsteps fading into the night.

On the counter, where Valenti had sat, there was a business card. Sammy picked it up and turned it over. It was blank on both sides. He put it in his pocket and poured himself a coffee that he would not drink, and sat in the dark and waited for morning that would not come clean.
