The linoleum floor tiles beneath Register 1 hummed with a heavy, rhythmic shudder.
Thud-chug. Thud-chug.
It was a deep, bone-grating vibration of exactly two point seven seven hertz. Down below the asphalt, through miles of abandoned limestone bedrock, the subterranean Master Printing Press of the Bureau of Shift Standards was grinding through its midnight cycle.
Julian Vance knelt on the black rubber mat, his sleeves rolled to his forearms.
Around him on the floor, three dozen brittle manila folders lay open like drying wings. Lin Mei sat cross-legged near the cigarette rack, her ink-stained fingers sorting through property survey manifests, while Dr. Beatrice Hahn rested her silver-framed bifocals on the bridge of her nose.
“Look at the foundation plate under the counter frame, Julian,” Dr. Hahn said, pointing her pencil toward the rear anchor bolt of Register 1. “Thomas didn’t file deeds in filing cabinets. He knew municipal inspectors would search cabinets during audits.”
Julian looked down at the iron stanchions. “He filed them directly into the structure.”
“Exactly,” Dr. Hahn said, kneeling beside him. “In nineteen-ninety-six, before the district was quarantined, Thomas had full access to the municipal engineering vault. When he installed Register One’s grounding loop, he embedded the primary easement covenants into the steel housing itself.”
