The flute player had been dead for two years when Henry first heard him sing.

It wasn't really singing, not at first. It was a sound, low and melodic, coming from somewhere outside Henry Walker's apartment window on North State Street. Henry was fifty-eight years old and had stopped caring what noises came through his windows sometime around 1920, when the world decided that everything bright and beautiful was somehow shameful and started hiding its light under a bushel of prohibition and moral panic.

He opened the window anyway. The night was warm for November, the kind of warm that makes you forget it's November and think you're still in September, still in that brief golden window when the city believes it's eternal. And there, on the fire escape below his window, sat a young man with a saxophone on his lap and his eyes closed and his mouth open and a sound coming out of him that made Henry's chest ache in a way he hadn't felt since—

Since what? Since Leo died? No. Since before Leo died, when Henry had still believed that words could mean something, that a sentence could carry truth the way a hand carries water, and that a story could change someone the way a storm changes a landscape.

The sound was beautiful. It was also wrong. It had the notes, yes—the right notes in the right order, the blues progression that ran through Chicago like a current under the street—but it had no soul. It was a perfect imitation of feeling, like a photograph of a face that isn't the face you remember.

Henry closed the window. He went back to his bottle. But he didn't sleep.

The young man came back the next night. And the next. Always on the fire escape, always at midnight, always playing the same progression with variations that suggested a mind working at the edges of understanding, grasping at something just beyond reach. Henry started leaving his window open. He told himself it was because the air was stuffy. It wasn't.

On the seventh night, the young man opened his eyes and looked up at Henry's window. He couldn't have seen Henry—Henry was in shadow, behind the curtain—but he looked right at him, and he nodded, and he played one more note, long and wavering and ending in a crack that was almost human.

Then he packed up his saxophone and disappeared down the fire escape.

His name, he told Henry the next afternoon when he came up the stairs and knocked on Henry's door, was Leo.

Henry stood in his doorway for a long time. The bottle was on the table behind him, half full, sweating in the warm room. He looked at the young man—Leo—standing on his threshold, and he saw his son's face. Not the face of the Leo who had died two years ago in a flu ward that smelled of carbolic and despair. This Leo was younger, fresher, the kind of face that hadn't yet learned what the world could do to it. But it was Leo's face. The same dark eyes, the same slight crook in the nose from when he'd fallen off his bike at seven, the same mouth that used to smile when Henry told bad jokes and pout when Henry told him to do his homework.

"Leo?" Henry said.

"Pop," the young man said. And his voice was Leo's voice, but different—deeper, rougher, like a record played a few too many times.

Henry let him in. He told himself it was because the apartment was too quiet. He told himself a lot of things.

Leo—because Henry decided, right then and there, that this was Leo, or close enough to Leo that the difference didn't matter—began to sing. Not on the fire escape anymore, but in the apartment, in the evenings, when the bottle was out and the curtains were drawn and the city outside was a wall of sound and light and motion that Henry had once loved and now tolerated.

His voice was extraordinary. It was the voice of a raven, Henry thought—not in the sense of being ugly or harsh, but in the sense of being ancient and knowing things that humans had forgotten. It had a quality that made people stop in the street. A quality that made Henry's old writer's mind race with possibilities, with sentences and paragraphs and chapters that might be saved from the ruin of everything he'd been working toward since 1910.

He didn't publish. Henry had stopped publishing in 1919, the year the world went mad and he went with it. But he listened. He listened to Leo sing and he heard, underneath the beauty, something that made his blood run cold.

Leo didn't understand what he was singing.

It wasn't that he couldn't feel it—Henry saw the way his eyes closed, the way his head tilted back, the way his fingers moved across the saxophone with a precision that bordered on the mechanical. He felt it, Henry realized. He felt it the way a machine feels heat, the way a camera feels light. He registered it. He reproduced it. But he didn't understand it.

Leo was a raven who had learned to sing like a man.

The realization came slowly, over weeks that bled into months. Leo got a job at a club on South State, a basement place with red walls and a stage that smelled of beer and sweat and desperation. He played on weekends, and the crowds grew, and he became popular, and Henry watched him from the back of the room, nursing his whiskey and feeling the familiar ache in his chest—the ache of a man who is watching something beautiful happen and knowing that he doesn't understand it and never will.

Leo's money appeared on the table every Monday. He didn't talk about the club. He didn't talk about anything, really. He ate what Henry put in front of him, slept in the chair by the window, and sang in the evenings. His voice got better. It got more polished, more professional, more empty.

Henry tried to tell him something once. It was 2 AM, and they were sitting at the kitchen table, and Henry had had enough whiskey to make him brave, and he said, "Leo, do you remember—the day you fell off your bike? You cried for an hour, and then you got up and fell off again, and you cried for another hour, and then your mother—God rest her—came out and sat on the porch and watched you fall and get up and fall and get up until you stopped crying and just kept going because falling became easier than crying."

Leo looked at him. His eyes were clear and bright and completely empty. "I remember," he said. And he did remember. He remembered every detail—the colour of his mother's dress, the exact angle of the sun, the taste of the pavement. But he didn't remember the feeling. He didn't remember why he had cried, or why he had stopped, or what it had meant to keep going.

He was a raven who had memorized the shape of a human life but never learned how to live it.

The end came on a Saturday night in March. The club was packed. Leo was playing his set, and the room was full of people who didn't know who he was and didn't care, people who just wanted something beautiful to happen to them for five minutes while the whiskey wore off and the music filled the space where their hearts used to be.

Henry sat in the back. He watched Leo play, and he watched the crowd, and he watched the way the light caught the sweat on Leo's forehead and made it look like gold, and he felt something inside him break. Not dramatically. Not like a storm. Like a thread, slowly, one strand at a time, until the whole thing just came apart.

After the set, Leo came home. He didn't go to the fire escape. He came straight to the apartment, and he stood in the doorway, and he looked at Henry, and he said, "I have to go."

"Go where?" Henry said.

"Back," Leo said. And he meant the river. He meant the reeds. He meant the place where he had been a bird and nothing else, before he had learned to wear a human voice the way a man wears a coat.

"Leo—" Henry began.

But Leo was already gone. He walked out the door, down the stairs, into the Chicago night, and he didn't come back.

Henry found the feather on the kitchen table the next morning. Black, glossy, perfect. He picked it up and held it in his hand and felt nothing. Not grief. Not relief. Nothing. The space where his son had been was still empty, and now it was emptier than before, because for a few months, it hadn't been empty, and now it was, and the difference was a wound that couldn't be closed.

He put the feather in a drawer. He went back to his bottle. And outside, Chicago went on being Chicago, beautiful and terrible and indifferent, a city built on the graves of people who had believed, for a moment, that something real had happened to them.
