Chapter 2 - THE SECRETS OF THE SEVENTH FLOORThe emergency hatch slammed shut behind them as Sarah and Callum scrambled up through the dusty, grease-slicked cables of the elevator shaft.

Sarah’s muscles screamed in protest. Sixteen hours on her feet, a missed lunch, and now she was scaling vertical service ladders like an urban combat operative, her navy scrubs tearing on a sharp bolt. Callum moved with lethal grace above her, his broad shoulders shielding her from falling debris, his hand reaching down to haul her weight upward whenever her footing slipped.
"Left cable," Sarah gasped, clinging to a metal rung. "If we trip the sensor here, the secondary fire doors on seven will seal shut."
"They won't," Callum said, his fingers flying across the burner phone she had handed back to him. Three keystrokes later, a muted click echoed through the shaft. "The building’s master grid is currently rerouting through a server farm in Bucharest. Harwick’s IT department thinks they’re experiencing a routine solar flare."
Sarah stared at him in disbelief. "You hacked the hospital's infrastructure from an elevator?"
"I invest heavily in green energy and digital architecture," Callum said flatly, pulling her up onto the seventh-floor maintenance catwalk. "Sometimes infrastructure requires maintenance."
The catwalk led directly to the utility vent of Room 714. Through the reinforced wire-mesh glass, the room looked like a sterile fortress.
Inside, little Leo Thorne lay motionless in a motorized hospital bed, hooked up to a rhythmic, beeping heart monitor. The boy looked impossibly small beneath the white sheets, his skin the color of old parchment, dark circles bruised beneath his closed eyes. A solitary IV drip hung from a metal pole, pumping a pale amber liquid into his thin arm.
And standing right beside the bed, looking at his watch, was Captain Vance of the Chicago Police Department's federal task force.
"Vance," Callum murmured, his voice dropping into a register so cold it made the air around them feel like ice. "He wasn't supposed to be on rotation tonight."
"He's running the sting," Sarah whispered, pressing her face close to the vent. "He’s waiting for you to walk through the front door so his sniper team can light up the hallway."
"Then we won't use the door." Callum unzipped his jacket, revealing a matte-black tactical harness strapped across his chest. From a specialized pouch, he pulled a small, circular glass-cutter fitted with a diamond-tipped diamond blade. "Sarah. When I drop this glass, Vance will draw his weapon within two seconds. The boy’s IV line is currently running a saline drip, but look at the pump—it's been modified."
Sarah squinted through the mesh. Her nurse's instincts flared instantly.
The digital display on the IV pump wasn't showing a standard saline rate. It was blinking a rapid warning code in red text: OVERRIDE - DOSAGE ALTERED.
"They spiked it," Sarah whispered, horror drenching her spine. "They didn't just want to trap you, Callum. They knew you were coming for a medical extraction. They rigged the infusion pump with a potassium chloride additive. The moment you walk in and pull him out, the monitor will register a sudden flatline, and Vance will claim you accidentally killed your own son during the struggle."
Callum stopped. The diamond cutter trembled in his hand—not from fear, but from a terrifying, volcanic rage that threatened to consume him whole.

"If I go in there now," Callum said, his voice dangerously low, "Vance kills my son, blames me, and walks out of this hospital a hero."
"Unless," Sarah said, her eyes catching the service tunnel latch beneath them, "we don't go through the glass."
