What the Photograph Said

He did not take the photograph down. He did not know why. It seemed wrong to touch it, the way it seems wrong to touch a gravestone with a stranger's name.

He took the lamp and went along the row again, slowly, reading every date. There were more than he had thought. Diana Chen at a bench, in goggles, with a soldering iron. Diana Chen asleep in a chair with a book on her chest. Diana Chen holding up a small bright thing on a chain, grinning like a girl who has won a prize, while a younger Luca pretended to bow. Under that one, in the neat hand, the border read: Prototype key, final assembly. "For the day we need to come home." D.C.

Archie leaned closer.

The thing in her fingers was a pendant. It was a teardrop of pale metal, no bigger than a thumbnail, with a hairline seam down the middle and a tiny stone set in the top. He had seen it a hundred times in the past month, rising and falling on a collarbone, humming against a girl's skin in the dark.

The Master Key.

Luca said the key was lost, he thought. Luca said nobody knew where it was.

Luca didn't know it was hanging round her neck.

He stood a long time in the red light.

Then, behind him, a floorboard creaked.

…

"Archie?"

It was Zoe.

She stood in the doorway of the darkroom with the lamp from the pod bay in her hand, and her hair was damp with sweat, and her face was bright with news. "I found the east wing. There are twelve beds in it, Archie, and every single one has a name card on the foot, and one of them says—"

She stopped.

She had seen the wall.

He watched it happen. He would remember it afterward with a clarity that frightened him. First her eyes went across the row of photographs, politely, as eyes go over any wall. Then they reached the end of it. They stopped. The lamp in her hand did not shake. It did not seem to move at all. But all the color went out of her face at once, like water out of a basin, and she took one slow step into the room, and then another.

"That's," she said.

"Zoe."

"That's my mother."

"I know."

"That's Mama." She was standing under the silver frame now, with her head tipped back. "That's her white coat. She wore it to my birthday once. She forgot to take it off." A laugh came out of her, strange and small. "She had that haircut for years. She said it saved time."

"Zoe, did you know—"

"No."

It came out hard and fast. She turned to him with her eyes enormous.

"No. I didn't. She said she worked in medical research. That's all she ever said. She said it was boring, that it was grant applications and paperwork, and I stopped asking when I was twelve." She pressed the back of her hand to her mouth. "She never said Luca. She never said Ferrara. She never once said Gate."

"Her name's on the plate. Co-researcher."

"I can see what it says."

"I'm not—" He stopped. "I'm sorry. I'm just telling you what's here."

"I know." She breathed. "I know. I'm sorry. It's just. It's her."

She reached up and touched the glass, over the laughing mouth, with one fingertip. The pendant against her breastbone gave a soft low pulse, like a heartbeat answering another one.

Archie saw it. He saw her feel it. He saw her hand go, without thought, to the chain.

"She gave me this," said Zoe, very quietly. "The week before I left. She put it round my neck at the kitchen table. Her hands were shaking so badly she couldn't do the clasp, and I had to do it for her." Her voice cracked. "She said, Wear it for me. It's an old thing. It's for luck."

"She said it was for luck."

"She said—" Zoe turned, slowly, and looked at him. "Archie. What am I looking at?"

…

He told her.

He did not decide to. It would be truer to say that he found, standing there with the lamp, that there was nothing else to do. He told her about the ledger in the basement, and the fourth chair, and the note signed D.C. He told her about the photograph of the prototype, and the border that read For the day we need to come home. He watched her face while he said it and did not look away.

When he had finished she sat down on the darkroom floor. She sat with her back against the bench and her knees drawn up, quite small, and she held the pendant in her closed fist and stared at the wall.

"She gave it to me," she said, "so I could come back."

"Maybe."

"She knew. She knew where I was going. She knew what I'd find." Zoe's mouth twisted. "She sat at the table and watched me sign the papers. She drove me to the airport. She never said a word."

"Maybe she couldn't."

"Maybe she was afraid."

"Maybe both."

"She's got Parkinson's, Archie, she's got nurses, she's, she's dying and she gave me, she put this on me—" She broke off, and put her forehead down on her knees, and for some time said nothing.

He sat down beside her. He did not touch her. He had learned, over the month, which silences wanted a hand and which wanted only company.

At last she lifted her head and wiped her face with her palm. "What do we do?"

"We go and find Jin," said Archie. "And Venn. We tell them what's here. We open the ledger."

"All of it?"

"All of it."

"Even the part about the key?"

He hesitated.

It was a very small hesitation. It lasted perhaps a second. But in that second a thought went through him, cold and thin and quite unwelcome, like a draft under a door. It had Jin's voice, and Jin's dry reasonableness, and it said:

Who else knows this girl came here with a key round her neck, and a mother who built it?

He pushed it away at once. He was ashamed of it. He looked at her tear-streaked face and her torn coverall and the spear lying across her knees, and he thought, That is Zoe.

But the thought did not entirely go. It sat at the edge of the room.

"Archie?" said Zoe.

"Yes. All of it."

…

They found the others on the second floor.

Jin was standing at a long bank of dead monitors with a sheaf of papers in each hand. Venn was lounging against the wall with his hammer over his shoulder, looking bored and rather pale. They both turned as Archie and Zoe came in, and their faces changed at once.

"What happened?" said Jin.

Archie told it again, shorter this time. He found it came out flat and orderly, like an architect's report: ledger, entry, fourth chair, photograph, plate. Zoe stood a little behind him and said nothing at all. Venn's mouth fell slowly open. Jin's did not. He listened with his head bent and his lips pressed together and a line appearing, and deepening, between his brows.

"Show me the pendant," he said, when it was done.

Zoe took it off.

She did it without a word. She lifted the chain over her head and held it out on her open palm, the pale teardrop turning gently on its seam, and Jin took it with the tips of two fingers and turned it to the light.

"It's warm," he said.

"It hums."

"I noticed." He frowned at it. "I noticed on the first day, actually. I thought it was a medical device." He glanced up. "Zoe. I'm going to ask you something, and I'd like you to understand I'm asking because it's my job to ask."

"Go on."

"When you signed up for the trial. How did you hear of it?"

"A flyer. In my oncologist's office."

"Whose office?"

"Dr. Okafor's. In Manhattan."

"Was she the one who recommended you?"

"She, no. I just saw it." Zoe's voice had thinned. "I was waiting for a scan. It was on the corkboard. It said Experimental protocol, terminal diagnoses, contact FDRI." She looked from one face to the next. "Why?"

"Because FDRI doesn't advertise," said Jin quietly. "Luca told me himself. The four of us were selected from a list of two hundred. Referrals only." He turned the pendant over. "Someone put that flyer on that corkboard."

Nobody spoke.

"Jin," said Venn. "That's. Come on. That's a stretch."

"Is it?"

"She's Zoe."

"I know who she is." Jin looked up. His face was not unkind. It was the face of a man trying with all his strength to be fair. "I'm not accusing anyone. But one of us has a mother who built this place, and a key that opens the door at the center of it, and a convenient flyer. And I'd be a fool not to ask what that adds up to."

"It adds up to nothing," said Zoe, fiercely. "I didn't know."

"You may not have."

"But you think I did."

"I think," said Jin, "that someone should."

Silence settled over the room, brittle and humming.

And Archie saw, with a lurch, that all three of them were looking at him.

It was the oddest thing. He had not asked to lead. He had never in his life wanted to be the one who decided. But it was the nature of the group, he saw, and always had been: Venn made them laugh, and Jin made them careful, and Zoe made them brave. And he was the one who held the blueprint. He was the one whom, in the end, they would follow through whichever door he opened.

Zoe's hand was held out, palm up, for the pendant. She was not looking at Jin now. She was looking at Archie. Her eyes were red and fierce and frightened, and in them was a question.

Do you?

Do you believe me?

Somewhere below, in the dark of the basement, the bulb was still swinging. Somewhere outside, a boy was waiting at a bridge. And in a lit room in another world, a man named William Cross had marked a date on his calendar, and was counting.

Archie looked at the girl with the outstretched hand. He looked at the thin pale teardrop in Jin's fingers. He thought of a ledger that said I could not turn her away. He thought of a mother who had put a key round her daughter's neck and said nothing.

Either she knew, he thought, or she didn't.

And I have to decide which, right now, without anything but my own heart to go on.
