Through the narrow wire-reinforced window of the diagnostic holding room at the far end of the hall, the man in the khaki service uniform was sitting upright against the wall. His jacket was torn, his right arm pinned awkwardly against his ribs by two plastic zip-ties, but his head was up. He wasn't looking at the ceiling or praying. He was watching Ward through the double-paned observation glass, tapping his left foot against the baseboard in a steady, deliberate rhythm. Three short taps, three long taps, three short taps.
An old naval distress sequence.
He wasn't an auditor who had walked in blind. He had deliberately allowed Calder to drag him past the perimeter cameras because the physical master logs were kept inside the sub-floor server room—a room only Harlan Ward’s private keycard could unlock from the inside.
Ward stepped into the vault, pulling the heavy steel fire barrier halfway shut behind him to begin cycling the drive arrays. On the wall beside me, the auxiliary circuit breaker box hummed as the primary storage banks began their manual purge cycle. If Ward initiated the complete wipe from inside the server room, every patient log from the last eighteen months would vanish into an unrecoverable parity loop within six minutes.
My employee badge hung from a blue nylon lanyard around my neck. It didn't have clearance for the executive servers. But it had maintenance clearance for the master sprinkler isolation valves mounted inside the utility chase directly above the vault ceiling.
I looked at the empty front doors, where rain was beginning to pool on the concrete drop-off lane. I could walk out into the dark, get into my ten-year-old sedan, and drive home to my kitchen table, leaving Riverside Regional to drown in whatever lies Ward had bought with hospital money. Or I could take the key dangling from my belt, pull the emergency fire override in the utility shaft, and lock Harlan Ward inside his own server vault before the first hard drive completed its wipe.
I didn't turn toward the exit. I stepped over the shattered glass, unclipped my brass master utility key, and pushed through the swinging doors into the triage corridor.
CHAPTER 2 CONTINUED
Across from the server racks, visible through the interior security pane, sat the diagnostic holding cell. The auditor in the torn khaki command uniform remained upright against the cinder blocks, his head tilted back against the wall, watching Ward’s reflection in the glass. His hands stayed bound by the plastic zip-ties across his stomach. He was not shouting, kicking the reinforced door, or fighting the nylon loops. He had stopped tapping his shoe. His eyes were locked on the master pre-action isolation valve four feet over Ward’s head, mounted on the very line running beside my hands.
The auditor understood the facility layout. He had not walked into the lobby blind; he had pulled the municipal blueprints from when Ward renovated the data core three years ago.
Directly beside my shoulder rested the yellow wheel of the primary pre-action sprinkler valve. Under state administrative code, healthcare facilities could not install chemical suppression above server rooms if adjacent perimeter rooms held patients; Riverside had settled on a pressurized pre-action line fed by the city main. If the emergency release arm tripped, forty pounds of compressed air would vent in three seconds, instantly opening the main clapper and flooding the server vault with high-pressure municipal water.
Every drive enclosure was rated water-resistant, but the sudden ground fault would drop the server chassis offline, aborting the active wipe and freezing the uncommitted sectors under a hardware fail-safe.
Ward’s phone chimed on the console. He tapped speaker without looking away from the purge monitor.
"Ward," he said.
Ray Calder’s rough voice came over the speaker, metallic and hollowed out by the concrete stairwell. "The front lobby is empty, Harlan. Her purse is still in her desk cubby, but she never clocked out at the turnstile. Her sedan is sitting in stall fourteen."
Ward’s fingers stopped over the trackpad. "Where is she, Ray?"
"Her security card didn't register at the employee exit," Calder answered. "The magnetic perimeter is active. She has to be somewhere inside the diagnostic corridor. Do you want me to search the rooms?"
"Check her station again," Ward said, his tone dropping into that flat, icy register he used before terminating nursing supervisors at sunrise. "Look under the linoleum. Sterling didn't have the green folio on him when you dragged him across the counter."
There was a short silence. Then Calder cursed under his breath. "The brass lock popped when he fought me. The binder slid under the desk."
