He asked Robert to place the reprinted cancellation beside the live reservation log. The cancellation bore a customer-approval timestamp of 9:10. Claire had torn the original at 9:11. The back-end had recorded consent before the passenger could possibly have given it.

“Somebody decided the conclusion before the argument was over,” Daniel said.

Robert stared at the time stamps. “And the printer delivered it because the desk had been told to finalize the denial.”

“Preserve the entire spool,” Daniel replied. “If the system printed a lie for me, it may have printed the same lie for other passengers.”

Robert opened a list of recent privileged actions. Three customer complaints had been archived. A maintenance alert was marked resolved. An instruction had been issued to stop preserving CCTV at one camera bank.

“That's illegal,” Claire said.

“It's certainly evidence of a serious compromise,” Daniel answered. “We don't know the whole story yet.”

Robert reached for the security phone. Daniel stopped him, gently, before he could dial the general alert line.

“We preserve the logs first. Then we notify the cyber-response team through an independently verified channel. Don't trust any contact number that pops up on this terminal.”

Robert looked at him in surprise. “You think the internal directory has been changed?”

“I think we shouldn't guess what has or hasn't been changed.”

The office door opened. A young ground agent named Mei Santos stood there with her face pale.

“Mr. Kline? I'm sorry. Someone sent a message to the counter terminals.”

“What message?”

Mei handed Robert a printed strip from the receipt machine. Across the top, in block capitals, the system had written: DO NOT ESCALATE INCIDENT 17.

Underneath was a single line: THE DIRECTOR'S FATHER WOULD HAVE UNDERSTOOD.

Daniel took the strip and read it silently. Robert turned toward him. “Your father worked here, didn't he?”

“Sixteen years ago.”

“I knew him.” Robert said the words reluctantly. “Not well.”

“Then you know he died in a maintenance accident.”

Robert's jaw tightened. “That's what the report said.”

Claire saw the significance of the answer before Daniel did. Not yes. Not he did. Only that's what the report said.

The security terminal chimed. It had rejected an attempted command to alter flight manifests. The request bore Daniel's electronic signature.

“Which flight?” Daniel asked.

Robert opened the blocked transaction.

FLIGHT 608 — DENVER.

REQUEST: RELEASE INCOMPLETE WEIGHT RECONCILIATION.

Daniel knew Flight 608: a regional passenger departure due to leave in fifty-three minutes. An unreconciled load report was not something any director should remotely waive for convenience.

“Call the safety desk on a known landline,” he said. “Tell them to keep that aircraft parked until the crew and an independent inspector complete normal checks. And Robert—”

“Yes, sir?”

“No one tells a captain to depart because my name appears on a screen.”

A printer below the monitor started again. This time it produced a single, perfectly legible line.

HELLO, DANIEL. WE KNOW WHAT THOMAS LEFT YOU.

CHAPTER 03 — WHAT CLAIRE DID NOT READ

Claire Donovan had worked twelve hours the previous day and slept for four. Her nine-year-old son, Noah, had a school concert that evening, and she had promised she would be there. During the first hour of her shift she had checked the clock twenty-six times, which was twenty-six more times than she had checked whether the passengers she dismissed had found another solution.

She knew that now. The thought gave her no comfort.

Claire remembered seeing the narrow strip and pushing it out of sight. She hadn't known it was evidence. That was the comforting explanation she wanted to give herself, but it wasn't complete. She had ignored it because any explanation requiring extra steps could count against her processing score. She had treated the machine as an authority even when it contradicted the person standing in front of her.

She was going to have to tell Daniel that she had never read the cancellation. She could almost hear him ask why, and her answer sounded pathetic even in her own mind: she had been afraid of falling behind in the morning rankings. There were better reasons to make a mistake. None of them belonged to her. She would tell him the truth anyway.

Daniel asked her to sit across from him in the staff interview room. Robert remained by the door. The independent shift lead had notified airport security, which was preserving recordings while the cyber-response team examined the second Omega session. Daniel placed his notebook on the table, open to the blank space beneath 9:11.

“I'd like your account before anyone has a chance to tell you what to remember,” he said.

“Am I suspended?”

“Your manager will decide your immediate work assignment under policy. I can tell you that you won't be serving passengers while the incident is reviewed.”

She swallowed. “I know it looks bad.”

“It was bad.”

Claire flinched at the simplicity.

“I've never torn a ticket before.”

“I hope not. Tell me what you saw on the screen.”

“Pending status. A red mark next to the record.”

“What did the mark mean?”

“I thought it meant payment rejected.”

“Thought, or knew?”

She stared at her shoes. “Thought.”

“Could you have opened the reason code?”
