A Name with a Boundary

Mercy had been moving east for less than an hour when Oliver stopped the engine beside a stretch of rail that had begun to lift from the ledge.

The track was still level beneath the wheels. Ahead, one iron bracket had torn loose, and the rail floated a handspan above the stone. Beyond it, the old line narrowed toward a pale gap. Nothing there showed how far the next solid support lay.

Nadia stood beside the open cab door, watching the rail shift in the windless air. “We can walk the ledge and see whether the bracket is the only break.”

“We can,” Oliver said. “Mercy stays here until we know what the line can bear.”

He checked the stabilizer gauge, then shut off the engine’s forward pressure. The needle settled. The train remained steady on the section of route it already held, but Oliver didn’t ask it to carry them toward the uncertain span.

He had the small notebook from the far signal house in his coat. Seris’s note was folded inside, its edges softened from being opened and closed. He left it there. The answer from behind the gauge plate belonged in a different place.

Nadia came back into the cab. “You’re writing it down?”

“If it stays in my head, I’ll keep turning it into a question.”

Oliver set a clean page on the console. The pressure gauge plate remained closed. He had no intention of making the presence repeat itself for the sake of a better record.

Nadia leaned against the wall, arms folded. “You have one question left?”

“I have plenty. I’m deciding whether any of them are fair.”

She looked at the rail through the cab window. “You could ask what it wanted Seris to understand.”

“That asks it to explain its reason.”

“I know.” Nadia’s hand went to the place beneath her ribs where the core rested. She withdrew it before her fingers touched the fabric. “I still want to know.”

Oliver waited. She had helped him keep the questions narrow before. This time, he would let her set the measure.

“Ask something it can refuse without having to defend itself,” she said. “Ask what the name asks of the train.”

Oliver looked at the closed plate. He had established a signal: one knock for yes, two for no. A signal wasn’t a summons. It did not make the next answer owed.

“If you want no more questions,” he said, speaking toward the gauge, “you can give no answer.”

He waited long enough for the cab’s ordinary sounds to return: metal ticking as it cooled, the faint tremor of the gauge needle, the far-off complaint of the lifted track.
