June turned. “The theater closed anyway.”

Walter lowered his head. “I know.”

“Benji spent years afraid of moving doors. My brother stopped speaking to me. I spent twenty years measuring a room that couldn’t explain itself because two men decided I couldn’t survive the truth.”

Nobody tried to comfort her. She picked up a miniature painted cottage and set it back down, carefully, so the tiny chimney would not break.

“What do you want from me now?” she asked.

“Nothing,” Walter said. “I want to stop Arthur from making another unsafe room.”

June looked at Lily. “What do you want?”

“I want the next child who sees those walls to be able to walk away safely. And I want to know why my father never told us.”

“He came to see me once,” June said. “A year after the accident. He asked whether I had found out who moved the stop. I told him no. He said he was sorry. I didn’t understand why.”

“He felt responsible?”

“He was the one who had insisted we build a model so the children would understand the room. He believed adults should understand it even better.”

June went to a cupboard and returned with a little painted paper star. “He gave me this after the theater closed. He said you had taken it from the set, and he wanted me to keep it until you were old enough to decide whether you wanted it back.”

Lily held the star. Its corners were bent, and a strip of tape clung to the back. She remembered carrying it home, though she could not remember giving it away.

“I don’t need you to forgive me,” Walter said.

“Good,” June answered. “Because tonight I don’t. Tomorrow we have work to do.”

13. THE DEMONSTRATION

By morning the parking structure’s heritage corner had acquired a temporary stage, a row of chairs, and a banner announcing a preview for investors and city representatives. Arthur had moved the schedule forward. The demonstration would take place at noon, before the theater’s final clearing.

June arrived with Walter, Daniel, Lily, and Nessa. A security guard refused to let them enter the work zone. Arthur appeared behind him, furious.

“You have no business here,” he told June.

“Neither does a moving wall without a proper stop,” she replied.

Arthur glanced at Walter. “You told her.”

“I should have told her twenty years ago,” Walter said.

“And now you’ll ruin another project to feel better?”

“I’m here because the project is dangerous.”

Arthur laughed. “The display is four feet high. Nobody can stand inside it.”

“A four-foot wall can still crush a child’s hand,” Lily said.

“Who are you to tell me how my machinery works?”
