The threat hung in the stale, dust-moted air of the study like a drawn blade. Vanessa’s fingers pinched Noah’s jaw so tightly that his teeth scraped against the soft inner lining of his cheek.

"Hold your breath!" Noah screamed, grabbing Lily and pulling his denim jacket over both their heads.

The white gas billowed down from the ceiling vents in thick, heavy clouds, rapidly filling the narrow concrete hallway. It wasn't the lethal nitrogen Eleanor had warned about—Julian still retained enough twisted, pathetic affection for his children not to murder them outright—but a high-potency gaseous anesthetic designed to knock out large animals in seconds.

Noah felt his head swim almost instantly. His knees buckled, a sudden, overwhelming weight pressing down on his eyelids.

"Noah..." Lily gasped under the jacket, her eyes rolling back as she sagged into his arms.

"No... no!" Noah forced his eyes open, fighting the creeping paralysis with every ounce of willpower in his body.

He looked at the glass room where his mother was frantically hitting the reinforced window with her IV pole. He looked up at the gallery window, where his father stood watching with a glass of scotch in his hand, his face unmoving.

The ledger, Noah thought through the fog in his brain. The ledger!

He reached into his pocket and pulled out his mother’s old silver fountain pen—a heavy, steel-tipped instrument she had given him for his twelfth birthday, before the fire.

With a desperate, roaring cry, Noah hurled himself forward toward the security control panel mounted on the wall next to Eleanor’s door. He jammed the sharp steel nib of the fountain pen directly into the exposed wiring loom running into the automated lock box.

Sparks exploded in a brilliant shower of blue and orange fire.

The electrical short-circuit triggered an emergency safety override built into the facility’s fire-suppression protocol.

With a deafening klaxon alarm ringing out—WOO-AAH! WOO-AAH!—the white gas vents automatically shut off, heavy overhead sprinklers activated, drenching the hallway in ice-cold water, and the pneumatic locks on Eleanor’s glass room popped open with a loud metallic release!

Julian gasped in the gallery, dropping his glass of scotch, which shattered on the floor. "What?!"

Eleanor didn't hesitate. Weakened, malnourished, and terrified, the maternal instinct inside her erupted with ferocious strength. She threw open the heavy glass door, rushed into the drenching water of the corridor, and scooped Lily’s limp body into her arms.

"Noah! Get up!" Eleanor screamed over the wailing alarms, grabbing Noah by his collar and dragging him toward the rear service exit of the lab.

Noah, coughing violently from the gas he had inhaled, forced his legs to move. "Mom... the ledger..."

"I have it!" Eleanor gasped, showing him the black leather book she had snatched off the floor where Noah had dropped it.

Above them, the gallery door burst open.

Julian came running down the metal spiral stairs into the lab, his suit soaked by the fire sprinklers, his face twisted in desperate panic.

"Eleanor! Stop!" Julian screamed, drawing a small chrome handgun from his coat. "Don't do this! If you leave this building with that book, there is no coming back! The syndicate will destroy us all!"

Eleanor stopped at the reinforced metal rear exit door. She turned around slowly, holding her unconscious eight-year-old daughter against her chest, rain-like water streaming down her face.

She looked at the man she had married, the man she had built a life with, and saw only a stranger wearing his skin.

"You destroyed us two years ago, Julian," Eleanor said, her voice piercing through the roaring klaxons with absolute, terrifying clarity. "We are just the ghosts coming back to collect the debt."
