The council members exchanged uneasy glances. Julian spread his hands.

“An archival attraction. Nothing dangerous. We’re simply reproducing a beloved local spectacle.”

“Then uncover it.”

He watched her for a moment. His smile remained, but it changed temperature.

“Of course.”

Two crew members pulled away the tarp, revealing a platform nearly twenty feet square. Its surface was divided into dozens of narrow wooden squares. Beneath it ran a forest of cams, belts, and vertical rods. A central brass wheel sat on a reinforced axle. The piece was ancient, complex, and strangely beautiful.

Mara knelt to examine the nearest square. The mechanism could lift it three inches, making a subtle wave pass across the floor. Or it could open a gap wide enough to catch an ankle.

“Who rebuilt this?” she asked.

“Specialists.”

“Names?”

“Certified specialists.”

“Certification for what?”

Councilwoman Ada Flores cleared her throat. “Julian, surely she can have the documentation.”

“Absolutely. A complete technical packet is coming.”

Mara touched the brass wheel. A shallow scratch ran around its rim, ending in four tiny notches. She had seen those marks before, in a childhood memory of Evelyn using a broken biscuit tin as a makeshift gear gauge.

“Is Evelyn involved?” she asked.

Julian’s expression didn’t move. “We invited her. She declined.”

“Did she approve this?”

“Evelyn hasn’t held an active entertainment certification in more than a decade. Her approval isn’t required.”

“Her design is being used.”

“Inspired by local history,” he said smoothly. “Very different proposition.”

Mara asked the crew to activate one section. Nothing happened. Julian said the control console was still being wired. She checked the platform’s underside with her flashlight and found fresh motor brackets attached to old framing. The actuator housings were new, but several pivot pins appeared hand-machined from a softer metal than she would have chosen.

“Do not let anyone stand on this,” she said.

Julian laughed lightly. “You make it sound like a death trap.”

“I haven’t tested it. That’s enough reason.”

After an uncomfortable beat, Councilwoman Flores agreed. Julian promised to leave it disconnected.

Mara took measurements and photographed the mechanism rather than trusting the company’s diagrams. At the far end of the gym, Leon pretended to sort lantern poles while watching her. As she passed, he murmured, “Ellis powered it up last night. I heard the gears through the wall.”

“Did it work?”

“For a while. Then one corner jumped.”

“Jumped?”

“Like the whole floor tried to kick something off it.”

Mara looked back at the polished platform. Under the overhead lights, the brass wheel seemed innocent, almost festive.

“Keep everyone away from it,” she told him.

As she went out the side door, Julian called after her.

“By the way, I heard about your camera. Terrible business. Must be unsettling to realize someone can walk straight up to your house.”

Mara turned. “Word does travel.”

“Small town.”

His yellow jacket disappeared back into the gym.

Gabriel Bellamy was waiting in Mara’s kitchen when she returned. He had made tea and failed to drink it. On the table sat a battered photograph showing eight teenagers, two adults, and a moving stage shaped like a crooked street of miniature houses.

Mara recognized Evelyn immediately. She was younger and grinning, with welding goggles pushed into her hair. Next to her stood Gabriel, one hand resting on the shoulder of a tall man with his sleeves rolled up.

“Who’s that?” Mara asked, pointing.

“Peter Vale. Evelyn’s mechanical partner. He built the first moving floor.”

“I thought she built everything.”

“She invented the illusions. Peter made them move.”

Gabriel turned the photograph over. A note read: ALICIA’S LAST NIGHT, OCTOBER 19.

Mara frowned. “Alicia?”

“Peter’s daughter. She was twelve. Loved the parade more than anyone.”

“Where is she now?”

“Lives in Portland, last I heard. She was hurt on the final night. Not badly enough to make headlines, but badly enough that Peter shut the machinery down.”

Mara examined the picture again. “Why would a platform hurt someone?”

“It shouldn’t have. That’s what nobody could understand.”

“Did Peter know?”

“He thought he did. Then he died the following winter, before he finished taking it apart.”

Mara laid the blue fob beside the photograph.

Gabriel flinched.

“Number four,” he said quietly.

“Tell me what it opens.”

“Peter kept four demonstration keys for the moving floor. They weren’t normal locks. Each key told a different portion of the mechanism how to move.”

“A key as a program selector?”

“Simple electrical contacts, really. Number four was the emergency rehearsal route. It was supposed to send every panel to a safe resting position.”

“Supposed to?”

Gabriel rubbed his forehead. “On the last night, the emergency route did the opposite. The platform pitched up under Alicia. She fell into the scenery and broke her collarbone.”

“Were there injuries beyond that?”

“Everyone got off. Peter tore apart the control unit and swore he’d never let it run again.”

“Where was the control unit?”

“Warehouse on Mercer Street. The building was sold. Most of the pieces vanished.”

Mara glanced at the silver USB. “And this?”

Gabriel took it between two fingers. “After the accident Peter was designing a replacement controller, one that wouldn’t depend on the old keys. He stored trials on these little drives. Evelyn found one and gave it to me, asked me to keep it away from the workshop until Peter had a chance to clear his head.”

“Did he?”

“No. Then there was the funeral, the sale, all of it. I put the box away.”

“You said you thought it was emptied.”

“I thought Evelyn had taken the blue key back. She came to collect some things a year later.”

Mara’s phone lit up. A message from Julian: FOUND YOUR MISSING CAMERA PROBLEM INTERESTING. LET ME KNOW IF YOU NEED SECURITY HELP.

She showed it to Gabriel. His face darkened.

“Why was Evelyn painting the camera?” he asked.

“That’s what we’re going to find out.”

“Don’t confront Julian alone.”

“Why?”

Gabriel tapped Peter’s picture. “Because that man knows considerably more about the old parade than he told the council.”

Evelyn’s garage was lit when Mara arrived just before sunset. Through the glass panes she could see ribbons of wood hanging from hooks, a stripped-down bicycle frame, and a hundred shallow drawers labeled in Evelyn’s neat handwriting. The garage door was open a foot. Mara knocked on the side entrance.

“Go away,” Evelyn called.

“I brought your ladder.”

A pause. “Leave it outside.”

“And I brought the blue key.”

Metal clattered inside. Evelyn opened the door just far enough to look out.

“Are you alone?”

“Yes.”

“Come in.”

Inside, the air smelled of sawdust and hot glue. Every surface carried half-finished objects: a tiny crescent moon hinged like a jaw, a paper heron with a folding neck, a wooden lantern frame. In the middle of the room stood a set of mechanical jaws clamped around a bundle of white feathers.

“You’re still making things,” Mara said.

“People still need things fixed.”

“These are new.”

“People still need beautiful things, too.”

Evelyn shut the door and turned the lock. “Show me the drive.”

Mara set it on the bench beside the blue fob.

Evelyn stared. Her expression changed from dread to disbelief. She pulled off a glove and touched the silver casing with one fingertip.

“Peter said he’d destroyed this copy.”

“Dad said you gave it to him.”

“Not that one. I gave him the testing copy. This is the final one.”

“How do you know?”

“Blue thread,” Evelyn whispered. “Alicia tied it there. She said no one could tell the drives apart.”

Mara explained what she’d seen in the school gym. At the mention of the new motors, Evelyn went still. At the mention of the four brass notches, she sat down hard on a stool.

“Did they put the floor together?”

“Yes.”

“The complete floor?”

“As far as I could see.”

“And Julian intends to run it in the street?”

“He says it’s a display.”

“He’s lying.”

“Why did you attack my camera?”

Evelyn looked toward the garage door. “Your camera records the sidewalk where the moving floor is being assembled. Brightline’s vans have passed your house every morning. I told them if they moved the machine again, I’d tell the neighborhood. Julian said he’d use your recordings to prove I’d interfered with the work.”

“That doesn’t explain the spray paint.”

“He told me he needed a clear recording of me approaching his van. That he could have me barred from the event if I even went near it. I thought if your camera was blinded, I could get to the van and remove the part that shouldn’t be there.”

“You were going to sabotage a vehicle?”

“Not the vehicle. A mechanical coupling. I made it thirty years ago. I know how to separate it safely.”

“Then why didn’t you ask me to turn off the camera?”

Evelyn gave her a look of exhausted impatience. “I sent you three notes.”

“I never got notes.”

“I put them through your letter slot.”
