The cast-iron turnstile at the elevator gate clicked with the sound of a cocked shotgun.
A heavy brass scanner housing, mounted directly onto the right-hand post of the scissor-gate, hummed at sixty hertz. Two crimson optical lenses glowed behind thick quartz glass, casting twin red crosshairs onto the ribbed threshold plate. Above the lenses, a mechanical departure drum flipped three times, showing black legal linotype on white porcelain:
[DEPARTMENTAL AUDIT CONVEYANCE]
[PRESENT CREDENTIALS FOR JURISDICTIONAL ENTRY]
“Single file,” Julian said, stepping up to the yellow line painted along the edge of the pit. “One at a time. Let the scanner register your serial numbers before you step onto the cage floor.”
Beside him, the cold mist off the flooded shaft swirled around their knees. The subterranean press on Sub-Level 6 hammered through the bedrock, its two-point-seven-seven-hertz pulse rattling the steel plates beneath their soles.
Julian looked down at his own right hand. He held his Starlight Mart Number 04 cash-drawer key -- Key Number 1-A. The brass was worn smooth at the edges from thousands of shifts, the notches bright from daily friction against the lock cylinder.
He pressed the flat blade of the key against the turnstile’s brass contact plate.
