Marcus was two miles away when the sound reached him — not the scream itself, but something older and more animal, a certainty that lived beneath thought. He had been sitting in a car outside a building where no meeting was scheduled, growing more uneasy by the minute, when his phone buzzed with a single text from an unknown number: a photograph of Elena's white robe, folded neatly beside the pool. He didn't remember the drive home. He remembered only the moment his tires screamed onto the gravel of his own driveway, the car barely stopped before he was out of it, sprinting across the lawn in the grey suit he'd worn to a meeting that had been a lie from the start. "Elena!" He saw her at the pool's edge — no, in the water, chained, her dark hair fanned out around her face as she struggled to keep her chin above the surface, the weight beneath her pulling steadily, patiently, the way something built to win always could afford to be patient. Marcus didn't slow down. He hit the water in a full dive, suit and shoes and all, the splash swallowing the last of the evening's silence. "I'm coming for you!" The words tore out of him half-formed, more prayer than sentence. But above them both, gears that had been engineered for safety were beginning to turn against them. The motorized pool cover — Marcus's own gift, his own precaution, twisted now into something else entirely — shuddered to life along its track, grey and heavy, beginning its slow, mechanical slide across the water's surface. Marcus reached Elena in seconds, his hands finding her shoulders, her face, the chain biting into her wrist. "I've got you, I've got you, where's the key—" "Victor," she gasped, water in her mouth, in her throat. "He dropped it — the drain — " Marcus's head snapped toward the patio's edge, toward the small brass grate glinting under the security lights, and understood in one cold instant that his brother had not just tried to kill his wife. He had designed her death to look like an accident that Marcus himself had built. Above them, the cover continued its slide, inch by inch, sealing the night sky away.
