“Not independently. A carrier approves each transaction.”

“Who approves it?”

“A properly credentialed operator.”

“Can the vendor create a request that looks like an airline instruction?”

“That would violate the contract.”

“That's not what I asked.”

Adrian's smile cooled. “I would need to speak with our engineers.”

A dozen screens separated the conference suite from the public terminal, but the tension reached Daniel anyway. For months, departments had sent one another carefully qualified assurances while an apparently ordinary service program quietly encouraged employees to trust false outcomes.

During a break, Priya joined him. “He didn't deny the system can present an overlay,” she said. “He denied it would be allowed.”

“Do we know who approved the altered training guide?”

“Not yet. We have signatures. We're checking whether the people themselves signed.”

Daniel studied a chart showing the program's monthly revenue. PremiereFlow made money when corporate clients obtained preferred treatment, but it also charged a 'service recovery fee' whenever an ordinary passenger's booking became disputed. Some disputes were genuine. Others appeared to have been created by the program's own instructions.

“It's collecting from both ends,” Daniel said.

On the screen the financial model resembled a pleasant chart of increasing customer satisfaction. Blue bars showed faster transaction times. Green bars showed fewer unresolved cases. No red bar indicated a passenger forced to buy a new ticket or a parent spending an additional night in an airport hotel. Those costs lived somewhere else: in personal bank statements, missed wages, and conversations between tired people who had nobody to call.

“Who decided these are the measurements of success?” Daniel asked.

Priya enlarged the proposal's signature page. Senior airport management had accepted the benchmarks, but the wording of the performance targets originated in Northstar's commercial contract. The line between supplier and customer had blurred. Elena's department reported the numbers that determined whether the vendor earned a bonus, using labels defined by the same vendor. There were legitimate reasons to let a software provider calculate service statistics; there was no good reason to let it be the only witness to its own performance.

Daniel wrote a note in the margin: **Who can dispute the number?** It was a simple question that no slide in Adrian's glossy presentation had answered.

“That is one possible explanation,” Priya answered. “We'll need accounts, not speculation.”

In another building, Elena Voss called Daniel from a private number. Her voice was quieter than during the morning meeting.

“I know you're looking at Adrian Mercer.”

“Why?”

“Because Thomas warned me about this kind of contract. I ignored him once.”

“Tell me what you know.”

“Not by phone. Meet me where the old staff cafeteria used to be. Bring Robert. And don't put the meeting on a shared calendar.”

He heard a door close on her end. Then the call ended.

Robert listened to the message and rubbed a hand over his face. “Elena never asks for witnesses unless she wants protection from her own words.”

“Then we'll go with independent security nearby,” Daniel said. “But not alone.”

The old cafeteria sat below the east concourse, a windowless room currently used for overflow storage. Elena was waiting beside a stack of chairs, holding a folder of payment schedules. She had left her phone in her office.

“Thomas was asked to certify an upgraded passenger-allocation system in 2009,” she began. “The system was sold as a way to reduce delays. In practice, its scoring rules treated certain travelers as less costly to displace.”

“Based on what?” Robert asked.

“Ticket price, history of complaints, willingness to challenge fees. It was dressed up as predictions about service needs.”

Daniel felt sick. “And Thomas refused?”

“He said the system would punish anyone least equipped to argue. He demanded a complete audit trail. Management called it an obstacle to modernization.”

“Who was management?”

“Some have retired. Some have died. One became the founder of Northstar Passenger Systems.”

“Adrian Mercer?”

“His father, Walter Mercer.”

Robert sat down hard on one of the stored chairs. Elena continued, staring at the floor.

“Thomas kept a physical copy of his objections. I helped him file it. When he died, I was told every copy had been destroyed in an electrical fire. I believed it for years. Then Adrian came back with PremiereFlow. I recognized the language.”

“Why didn't you tell me?” Daniel asked.

Elena's answer came without self-defense. “Because telling you would mean admitting I helped make the original report disappear. Not by deleting it. By accepting a summary I knew was incomplete.”

The air-conditioning clicked on overhead. Daniel wanted to shout. It would have been easy. Instead he asked for the folder and arranged for an investigator to log it.

Elena placed it on the table. “I kept copies of the payments the vendor received for 'incident optimization.' I didn't know what they meant then.”

Daniel opened the first page. Beneath the invoice references, a description had been highlighted in yellow: **EXCEPTION REDUCTION — PASSENGER DISPUTE RECLASSIFICATION.**

The payment recipient was not Northstar.

It was an account held by a subsidiary whose registered director had a familiar name: Robert Kline.

CHAPTER 09

Robert'S Signature

Robert Kline stared at the company registration as if the ink might disappear under sufficient scrutiny. The company, Kline Aviation Services, was incorporated in 2011 and held an account that had received consultancy payments from a Northstar subsidiary. He did not deny the name was his. He denied knowing that the company still existed.
