I.

The mirror caught the moonlight at eleven minutes past ten, and Jack Calloway stood in the field upstate and watched a beam of silver cut across the dark like a blade drawn from its sheath.

He had built it himself, with hands that still remembered how to weld aircraft aluminum and a mind that had never learned how to stop doing impossible things. Three hundred feet across, parabolic curve polished to a smoothness that made the night sky look like it was lying on water. The frame was steel beams salvaged from a demolished Manhattan bridge, and the reflecting surface was sheet silver, hammered flat by a craftsman in Yonkers who charged Jack three weeks of back rent for the job and told him, without irony, that he was either a genius or a madman, possibly both.

Diana watched the beam from the road, standing beside her car with a notebook she had not opened. She had driven up from the Village at seven, after spending the afternoon at her father's house watching him entertain people he did not like about things he did not understand, and she had not slept because sleep had become something that happened to other people.

The beam stretched across the valley toward Cat Mountain, twelve miles away, and disappeared into the darkness with a precision that made Diana feel, for no reason she could name, that she was watching someone throw a rope across an abyss and hoping something on the other side would catch it.

"It's beautiful," she said, and the word felt inadequate, the way words always felt inadequate in the presence of Jack's particular brand of devotion.

"It has to be," Jack said. He was standing by the control panel—a collection of dials and switches and a clock he had built from a discarded ship's chronometer—adjusting the mirror's angle with a crank that made his shoulders move in the way that made Diana want to look away and couldn't. "If the angle is off by even a degree, the beam scatters. It has to be a line, not a light."

"You've done this before," Diana said. It was not a question.

"Three test fires," Jack said. "All successful. The beam reaches Cat Mountain every time. The question is whether anyone is there to see it."

Diana did not ask who "anyone" was. She had learned, in the three weeks she had been spending up here, that some of Jack's questions did not have answers and that the not-knowing was the point.

II.

They had met at a party in the Village, at a apartment that belonged to a painter named Harold who threw parties for people who pretended not to care about money while spending money they clearly did not have. Diana had gone because her friend Polly had asked her to, and because staying at her father's house on a Wednesday was worse than going to a party she did not want to attend.

Jack was standing on a chair in Harold's living room, holding a glass of something amber, telling a story about flying over the Channel in 1918 in a plane that was more wood and fabric than machine, in weather that was more hostility than atmosphere, and about a woman—her name was Claire, she flew Spads, she had a laugh that could be heard over any engine—who had vanished into gray cloud and never come back.

"I don't believe she's dead," Jack said, and his voice did not change level, which was what made Diana listen. "I know everyone believes it. I know the War Department believes it. I know that if I asked ten people on the street whether Claire Sterling—no, Claire Monroe—lives or dies, nine of them would say dead and the tenth would say dead with sympathy. But I saw her plane when it went down. I saw it turn, just for a second, into sunlight. And dead things don't turn into sunlight."

People were smiling the way people smile at veterans' delusions—with the careful tenderness of someone handling a wounded animal. Diana found herself smiling too, but for a different reason: she recognized the shape of what Jack was doing. He was building something out of loss, the way some people build cathedrals or write symphonies or start companies. He was taking the raw material of something terrible and arranging it into a form that could be looked at without looking away.

She went up to him after the party, when the music had stopped and the guests had thinned to the people who stayed because they didn't want to go home. She stood in front of him on the chair and said, "What are you building?"

"A mirror," he said.

"To do what?"

"Reflect moonlight. On a clear night, I can focus it onto a signal tower on Cat Mountain. Twelve miles. A beam of light, precise as a laser, bright enough to be seen from anywhere in the world if anyone's looking."

"Why?"

Jack looked at her in a way that she would remember for the rest of her life: with an openness that was either the bravest thing or the most foolish thing he had ever done. "Because if she's alive, and if she looks up at the moon on a clear night, and if she sees the light change—just a flicker, a moment of brightness where there was darkness before—she'll know. She'll know that someone is thinking of her."

Diana, who had spent twenty-six years surrounded by people who told her what she wanted to hear in order to get what they wanted from her, heard in Jack's words something she had never encountered: a request that asked for nothing in return.

"I'll help you," she said.

III.

The mirror took six weeks to complete. Diana managed the finances, which meant she wrote checks to people she didn't understand for work she couldn't visualize, and she tried not to think about the amount that was appearing on her father's quarterly statements under the heading "Diana—Personal."

Jack worked from dawn until the light failed, his hands covered in silver dust, his shirt permanently stained with oil and sweat and the red clay of the upstate soil. He ate standing up, usually from a tin that Diana had brought from the city, and he talked to himself in a low murmur that Diana assumed was either concentration or madness, and she couldn't tell which.

Professor Finch, Jack's mentor, came up on weekends. Finch was a retired schoolteacher who had built three telescopes in his basement and published nothing in any journal that mattered. He stood beside the mirror on its second night and looked at the polished surface and nodded slowly and said, "Ezekiel Cheyenne would have approved."

"Who's Ezekiel Cheyenne?" Diana asked.

"An amateur astronomer," Finch said. "Built a mirror in 1892. Twelve feet across. The largest privately constructed reflecting surface in the Western Hemisphere at the time. He used it to search for a comet that he believed was real and that no one else could see. He died believing he had seen it. The scientific community decided he had seen nothing but a cloud."

Jack didn't look up from what he was doing. "I'm not looking for a comet."

"No," Finch said, looking at Jack in a way that suggested he understood, better than Jack probably understood himself, what Jack was looking for. "You're looking for a person."

On the third week, Diana and Jack sat on the steps of the barn one evening after the work was done, drinking lemonade that had gone warm because neither of them had put it in the icebox. The mirror stood behind them, catching the last light of day and holding it, glowing faintly like something alive.

"Do you think it's absurd?" Jack asked.

"Yes," Diana said. She had been expecting him to ask this, and she had been expecting herself to answer honestly. "I think it's profoundly absurd. I think you are spending a considerable amount of money on a mechanism whose sole purpose is to send a signal into darkness with no expectation of receiving anything back. I think, by every rational standard, you have lost your mind."

Jack was quiet for a moment. "And by irrational standards?"

"By irrational standards," Diana said, "it's the most reasonable thing I've ever heard."

She didn't expect him to understand why she said it. She wasn't sure she understood it herself. But the words were there, and they were true, and they hung in the warm air between them like the mirror's faint glow.

IV.

The full moon rose on a night so clear that the stars looked close enough to touch. Diana drove up to the field at six in the evening and found Jack already in position, standing by the control panel in a clean shirt that she had ironed for him that morning, looking like a man about to conduct an orchestra that consisted of a single instrument and an audience of zero.

They waited. The moon climbed. The field turned silver.

At eleven minutes past ten, Jack turned the crank. The mirror shifted, caught the moon, and sent the beam across the valley toward Cat Mountain, where the signal tower—a rusted structure left over from a failed radio company in the 1920s—stood against the sky like a question mark.

The beam was perfect. Diana could see it: a solid column of light, sharp as a drawn line, disappearing into the darkness and striking the tower with visible force, as though the tower were made of glass and the light were heavy enough to break it.

They waited.

Ten minutes. Twenty. An hour.

Nothing returned. No flash from the tower, no signal, no sign that the beam had been seen by anyone or anything.

Jack stood in front of the mirror for a long time after the moon had moved past the optimal angle and the beam had faded to nothing. He was still, in the way that people are still when the thing they have been preparing for their entire lives has arrived and turned out to be exactly what they expected and therefore was not enough.

Finally he turned to Diana. "I suppose she's not out there."

Diana opened her mouth. The lie was there, ready and simple: she had seen a light flash back from the mountain. All she had to do was say it. It would cost her nothing. It would give Jack everything.

But Diana Sterling had spent her life surrounded by people who lied because lying was the currency of her world, and she was tired of speaking a language that meant nothing.

"I didn't see anything," she said.

Jack nodded. He didn't look disappointed. He looked relieved, in a way that surprised her—relieved that the question had been answered, even by an answer that answered nothing.

They drove back to New York in silence. The city was bright and loud and full of people pretending that everything was fine, and Diana watched the dark fields pass by and thought about the mirror standing alone in the field, catching moonlight and sending it into a darkness that had not answered.

She got out of the car at her family's mansion. The doorman opened the door. The house was full of light and noise and people who would ask her tomorrow how it went and she would tell them it went well and they would believe her and she would let them believe it.

Jack drove north.

Diana went to her room and stood at her window and looked up at the moon, which was bright and indifferent and beautiful, and she thought: somewhere out there, a mirror is catching your light and throwing it back at a darkness that may never answer, and that is a thing that has been done, and that is something.
