Part 3: Show Us the Send
The sentence at the end of Leah’s challenge hung in the basement longer than the rig’s cooldown clicks. She had said, “Open the rig. Set the same window. I’ll show you exactly how she did it,” and for a second nobody in the public workspace moved except the fan blades inside the bay housing.
Eli looked at Nora because she was the one being accused, but she was still watching Leah and the machine, not the crowd. Her hands were empty now. The safety goggles sat in a crooked stack on the folding table where the family had left them.
Professor Rusk said, “There is no same window. The board is visible. The room is visible. That claim has already failed once.”
Leah turned one shoulder toward the crowd, not enough to stop facing the bay. “Then run a live one. If this basement can move information, move this. Let everyone see the method instead of protecting her.”
A student by the stair door said, “Yeah, if it’s fake that should prove it.” Another voice answered, “Or prove she did it.”
The room was doing the same thing it had been doing since Leah came in: trying to keep the first ugly story alive by demanding one more performance.
Professor Rusk did not raise her voice. “A demonstration pulse is not a trial,” she said. “But a paper send has physical requirements. If we do anything, it happens under handling rules, in view, and with the object we already have.”
Nora spoke before Leah could answer. “Ask to see the lower edge first.”
Leah’s head snapped toward her. “Why?”
“Because paper sent through this cradle picks up guide dust and clamp dents,” Nora said. “Every time. The felt strips in bay two leave amber drag on the bottom edge. It’s ordinary. Eli knows that.”
Eli did know it. He said so because the line of visitors nearest him had already turned his way. “The demo postcards by the stair rack get it if we run them as examples. Two shallow bites from the clamp, near the corners.”
Professor Rusk held out her hand. Leah did not want to give the postcard back, but she did. The professor tilted it under the task lamp, then passed it to Eli. He looked at the lower edge. There was the postal smear, the soft paper, the bent corner, and nothing else. No amber trace. No paired dents.
He said exactly that.
Leah answered too quickly. “Then the marks wore off.”
Nora shook her head once. “Not from coated stock. Not before the mail cancellation stays visible.”
The family with the two kids had not left after all. The older kid whispered, “So it didn’t go through?” His mother put a hand on his shoulder, but she did not hush him this time.
Professor Rusk looked toward the bay clock, then at the console beyond the shield partition. “There is one calibration pulse in eleven minutes,” she said. “Receive and send alignment only. If this object is run, nobody touches the controls except on my instruction. Leah, if you insist on proving your claim, you handle the postcard yourself in open view.”
Leah lifted her chin. “Good.”
“And if the object picks up first-transfer marks now,” Professor Rusk said, “your story changes in front of the same people who heard it.”
No one answered that. Even the whispering near the corridor dropped.
They moved as a group without quite meaning to. Professor Rusk opened the waist-high gate to the rig bay. Eli stayed at the threshold with the visitors because that was where she pointed him. Nora did not crowd forward. She stopped near the lanyard rail again, blue tags hanging still beside her shoulder.
Inside the bay, the ordinary details of the room got louder than the people. Fans. Relay clicks. The squeak of Professor Rusk’s shoe on the sealed floor. The rustle of a paper sleeve taken from the send drawer. She held it up for the room to see.
“Standard paper cradle,” she said. “Everyone watch the edge before insertion.”
Leah stepped in beside the machine. One hand kept flattening the postcard against her palm. The bent corner lifted and dropped each time.
Eli noticed one more thing when she turned it over under the bay light. On the picture side, the campus bookstore logo sat in the same place as the souvenir postcards in the wire spinner by the stair door. There were still three of those left in the rack, same boardwalk image, same glossy coating.
Nora noticed it too. “That image is sold upstairs in the student store,” she said. “It isn’t custom stock.”
Leah did not look at her. “Plenty of people buy postcards.”
Professor Rusk pointed to the cradle. “Insert it. Bottom edge first. If your accusation depends on the rig, the rig gets the object now.”
Leah took one step closer. For the first time since she came down the stairs, she hesitated long enough for everyone to see it. Then she slid the postcard into the cradle with her own hand.
The amber alignment lights came on, and the clamp arms started to close.
