Chapter 1 - The Silver Key and the Broken OathThe cold in the hallway did not come from the open window at the end of the landing; it came from Mr. Doyle.

For three years, the landlord had been a fixture of the building—a man who smelled faintly of stale tobacco and floor wax, someone who knocked twice, mumbled about late fees, and shuffled away. But tonight, Mr. Doyle’s shoulders were squared. His chin was tilted up in a way that erased the stoop of his age. Most disturbingly, his left hand—the one braced against the doorframe—was bare, revealing an intricate, sprawling tattoo across the back of his wrist: a coiled adder biting its own tail, identical in style, though newer, to the tarnished silver wolf’s head hanging against Cookie’s chest.
"You're late with the water surcharge, Mia," Doyle said. His voice wasn't his own. It was flatter, dropped an octave, carrying the precise, clipped cadence of a man used to giving orders in rooms where people didn't survive hesitation.
Mia’s hand tightened around the door handle. "Mr. Doyle? What are you... how did you get this key?"
"A spare," Doyle said smoothly, stepping forward into the warm, stale air of the apartment. "One always keeps spares for the properties one manages. Or owns." He didn't look at Mia. His small, watery eyes slid past her shoulder, fixing entirely on the dark corner by the radiator where Cookie stood.
The dog was no longer shaking. Every muscle in his massive frame was drawn taut, stretched like bowstring iron. The gash above his eye, still pink and healing from Mia’s careful stitching, seemed to pulse with a faint, silvery luminescence under the flickering hallway bulb.
"Don't," Mia whispered, stepping into Doyle's path. "Whatever you're doing, get out. I'm calling the police."
"The police, little bird?" Doyle let out a short, dry chuckle that held no humor. "The police in this district answer to the same ledger I do. Or rather, they used to, before the house fell into disarray eight months ago." He took another step inward, his gaze never leaving the dog. "Magnificent, isn't it? They said the curse would rot him from the inside out. They said a true beast of the syndicate would die whimpering in an alley, stripped of his shape, his voice, and his throne."
Cookie stepped forward.

It wasn't the clumsy gait of a stray. It was slow, deliberate, and impossibly heavy. With every inch the dog moved, the air in the tiny room seemed to drop ten degrees. The floorboards didn't creak; they groaned under a weight that shouldn't have belonged to a creature of flesh and blood.
"Eight months, Viktor," Doyle murmured, his voice dropping to a harsh whisper as he reached slowly into his coat pocket. "The council sends its regards."
