Chapter 10 - THE SUBTERRANEAN DOOR

RUMBLE.
The floor beneath us groaned. A deep, mechanical grinding sound echoed from the rear utility corridor behind the manager's office, vibrating through the thick concrete foundation of the building.
Mr. Harrison gasped, clutching his chest as he stared toward the back hallway. "The old storm shelter... they're opening the old storm shelter."
"It was never a storm shelter," Unit Seven corrected coldly, slipping the communicator back into his pocket. "It was the primary pneumatic transfer link constructed during the Cold War. It connects directly to the subterranean freight rail network beneath the city."
The heavy fire door at the end of the corridor blew inward with a sharp pneumatic hiss, billowing a cloud of cool, dust-laden air into the red-tinted lobby.
Two tall figures stepped out from the shadows of the utility tunnel. They wore matte-black tactical gear, their faces hidden behind seamless, featureless visors that absorbed the pulsing red emergency lights. They carried no visible weapons, but the tactical rigging across their chests bristled with high-tech data-tether modules.
They didn't look at me. They didn't look at the sobbing robber. They walked in synchronized unison straight toward Unit Seven, flanked him instantly, and turned to face the room.
"Auditor Seven," the lead operative spoke, his voice modulated through an internal speaker. "Extraction corridor is clear. Bring the package."
Unit Seven turned his cold, ancient gaze one last time toward me.
"Thank you for your cooperation, Detective Miller," the boy said formally, offering a stiff, military-style nod. "You handled the amateur element efficiently."
Before I could lunge forward to block their path, the boy turned and walked briskly toward the dark open maw of the subterranean tunnel, flanked by the two silent operatives. Mr. Harrison scrambled up from the floor, weeping hysterically, and was gently but firmly guided into the tunnel behind them.

The heavy pneumatic door began to close automatically, sliding shut with a heavy, final seal.
I stood alone in the pulsing red glow of the lobby, the amateur robber sobbing loudly behind me against the checkered tiles, realizing that the ghost of Westbridge had just walked back into the dark—and I was left holding the pieces of a mystery that the federal government had tried to bury ten years ago.
