Eventually, I stopped imagining anything at all.

I had learned to live with a question that had no answer.

Now his handwriting was in front of me.

I read the next lines silently.

If this reaches you, then something has happened that I could not prevent. I need you to know that leaving you was never what I wanted. Whatever people tell you about that last mission, please remember that there are things you may never be told.

The letter ended abruptly.

There was no signature.

No explanation.

No promise that he would return.

Just one final sentence.

Trust the man who brings you this letter, but ask him what his father did after I disappeared.

I looked up so quickly that Daniel stepped back.

“What did your father do?”

His face changed.

For the first time, he looked less like a man delivering a message and more like someone who had spent years dreading the moment a particular question would finally be asked.

“I don't know everything,” he said. “But I believe my father helped someone after the mission. Someone who was never officially accounted for.”

“Was it Thomas?”

“I think it might have been.”

The words struck me with such force that I had to sit down.

Fifty-five years.

Fifty-five birthdays without him. Fifty-five anniversaries of a disappearance that had divided my life into before and after. Fifty-five visits to a memorial where I had left white roses beside his name.

And now someone was suggesting that the story I had accepted for half a century might not be complete.

“Why didn't your father tell the authorities?” I asked.

Daniel looked toward the windows.

“He was afraid. I don't know whether he was afraid of making a mistake, exposing someone, or revealing something that could put others in danger. He never explained it fully.”

“That isn't enough.”

“No,” he agreed. “It isn't.”

For the first time since he had stepped out of the cockpit, I believed him—not because I knew his story was true, but because he was not pretending to have every answer.

He had questions of his own.

And perhaps that was why he had found me.

I folded the letter carefully and returned it to the envelope.

“Where are these documents now?”

“At my home. There are notebooks, copies of correspondence, and a small metal case my father kept locked. I haven't been able to establish what everything means.”

“Then we need to see them.”

Daniel nodded.

“I hoped you would say that.”

The flight attendant returned to tell us the ground crew was waiting to complete the arrival procedures. I stood slowly, holding the envelope with both hands.

Before leaving the aircraft, I turned toward Daniel.

“One more question.”

“Of course.”

“Did your father ever say whether Thomas was alive after the mission?”

Daniel hesitated.

Then he reached into his pocket and produced a small photograph I had not seen before.

It was badly faded, with a crease running through the center. The image showed a man standing outside a modest building, his face turned slightly away from the camera.
