Chapter 17 - The boots on the iron stairs
Arthur Vance stepped through the doorway, holding a heavy chrome fire extinguisher like an iron club, his knuckles white with fury. Beside him stood two Calloway security veterans, their tasers drawn and leveled directly at Ethan's chest. "Step away from Miss Calloway, Mr. Mercer," Arthur said, his dignified butler's tone replaced by the hardened steel of a man who had fought beside Frank Calloway in union strikes forty years ago. Ethan gasped in shock, using Clara as a human shield for half a second before shoving her violently into Arthur's arms and bolting down the stairwell toward the basement levels.
"Arthur! He has the detonator for the southern foundation valves!" Clara cried out, clutching Arthur's sleeve as she regained her footing. Arthur immediately pressed his lapel microphone, his voice cutting through the building's emergency radio frequency. "Mr. Calloway, intruder is descending via Stairwell B toward Level Zero. He is armed with an electronic bypass trigger. Alert municipal response immediately." Over the speaker, Frank’s deep voice answered without a trace of panic. "Cancel the municipal call, Arthur. The police cannot navigate the historic sub-levels without the analog schematic. Lock all exterior fire doors from the lobby, secure Clara in the security bunker, and meet me at the freight hoist."
Down in the deepest sublevels of Calloway House, the temperature dropped rapidly. Ethan ran through the subterranean concrete tunnels, past roaring ventilation fans and industrial cooling towers that rattled behind wire cages. His shoes splashed through stagnant puddles of maintenance runoff. Ahead of him, a reinforced steel hatch marked with faded yellow warning paint stood ajar. The heavy padlock on the chain had been sheared off cleanly with high-grade industrial bolt cutters. Julian Sterling's hired demolition specialists were already inside. Ethan let out a ragged laugh of triumph as he wiped sweat from his eyes and plunged into the pitch-black corridor of Level Zero.
