The Passenger Who Never Boarded

The original records of Flight 731 were stored on an old server outside the airline's regular system. Adrián managed to access them with the help of a computer specialist who worked for the police.

The file revealed a different passenger list from the one currently stored in the system.

There were three additional names.

All belonged to people who had been reported missing during the previous six years.

Gabriel Montes was one of them.

The second name belonged to a businessman who had disappeared after exposing a corruption scheme. The third belonged to a woman who had left her home without taking her documents, money, or luggage.

All three cases had been closed without a convincing explanation.

Adrián opened the corresponding police reports. Every file carried the same signature: that of the commissioner in charge of the criminal investigation division.

The same man who had supervised Laura's case.

The computer specialist interrupted him.

“Inspector, there's something else. The original records have been altered several times. Someone deleted the names, changed the seat assignments, and replaced the surveillance footage.”

“Can you recover the previous files?”

“Some of them. But there's something strange. The changes were authorized using your credentials.”

Adrián felt his stomach tighten.

“That's impossible.”

“The system shows that the access came from your terminal six years ago.”

He said nothing. He stared at the screen as though he were reading someone else's life story.

That night, he received another message from Laura. It contained only an address and a time.

An abandoned warehouse on the outskirts of Madrid.

Adrián went there without informing his colleagues. He found the door slightly open and a dim light inside. Photographs, documents, and several false identification cards lay scattered across the floor.

At the far end of the warehouse, Gabriel Montes sat at a table.

He looked older than he had in the photograph, with a tired face and a scar near his eyebrow.

“Finally,” Gabriel said. “I thought you'd never come.”

Adrián pointed his gun at him.

“I want answers. Who are you? Why does my name appear in these documents?”

Gabriel made no attempt to escape.

“Six years ago, your team received a tip about a network that created false identities for people who needed to disappear. Some were criminals. Others were witnesses someone wanted silenced. The network controlled flight bookings, boarding records, and surveillance footage. It could make it look as though someone had traveled to another country when, in reality, they had never left the place where they were hiding.”

“And Laura?”

“Your sister?” Gabriel asked.

“No. Laura Montes.”

Gabriel lowered his eyes.

“Laura worked in cybersecurity. She discovered the network and realized that people inside the police were protecting it. When she tried to expose the operation, she was hunted down. The car accident was staged to make everyone believe she was dead.”

“And me? What do I have to do with this?”

Gabriel opened a folder and pulled out a report.

On the last page was Adrián's signature.

The document authorized an operation carried out on the night Laura disappeared.

“You were involved in the investigation,” Gabriel explained. “You discovered who was controlling the network. But before you could hand over the evidence, something went wrong. After that, the records were altered, and your memories of the operation began to disappear.”

“Are you saying someone erased my memory?”

“I'm saying you can't remember everything that happened. And someone made sure of that.”

Adrián felt a sharp pain in his head. Vague images surfaced in his mind: a dark corridor, a siren, a woman screaming his name.

And an airplane.

Flight 731.

“Why was your passport on the plane?” he asked.

Gabriel moved closer to the table.

“Because someone needed to believe I had boarded. While everyone was searching for a missing passenger, no one was looking for the man who had never reached the airport.”

“And Laura? Where is she?”

A voice answered from behind him.

“I'm here.”

Laura appeared at the entrance to the warehouse. She had the same face Adrián had seen in the recordings, although her hair was shorter and a faint scar marked her chin.

Adrián slowly lowered his gun.

“Why didn't you go to the police?”

“Because the police weren't safe,” she replied. “And because you were the only person who could prove what happened. But I didn't know if you could still remember.”

Laura handed him a small USB drive containing the recovered files. Among them were recordings, bank transfers, and messages linking the commissioner to the network of false identities.

“Is this enough to arrest him?” Adrián asked.

“If the files are published before they disappear, yes.”

At that moment, they heard engines outside.

Gabriel switched off the light.

“They've found us,” he whispered.

Laura pulled Adrián toward a side exit. The two of them ran to the road and boarded a train just minutes before the agents arrived.

During the journey, Adrián began recovering fragments of his memory. He remembered helping Laura escape that night. He also remembered the commissioner giving him a choice: forget the case or face charges of treason.

He didn't know how they had managed to erase parts of his memory, or who had helped him survive inside the police force itself. But now he had enough evidence to begin dismantling the network.

The following morning, a journalist received an anonymous envelope. Inside were the Flight 731 files, documents linking the commissioner to the three disappearances, and a photograph of an empty airplane seat.

On the back of the photograph, someone had written:

“The next passenger has already boarded.”

Beneath the sentence was a name.

The commissioner's.

Three days later, the man disappeared without a trace. His car was found near Madrid Airport. Inside lay a plane ticket to a destination that did not exist in the airline's system.

The passenger's assigned seat was 14A.

The same seat where everything had begun.

Adrián never saw Gabriel again. Laura disappeared as well, leaving behind only a message:

“Some truths survive only as long as no one knows where to look for them.”

Months later, an airport employee discovered another passport beneath seat 14A on a plane that had just landed.

This time, the name on the document was Adrián Vega.

But the inspector was alive, at home, thousands of miles away.

Or at least, that was what he believed.
