Meanwhile, deep within the Shadow Dealers compound

  Operator 47’s footsteps echoed through the empty hallways of the facility, each fluorescent light flickering out as he passed. Behind him, he could hear something else—not footsteps, but a wet, slithering sound, as if the walls themselves were becoming organic, pulsing with alien life. The corridors were turning into jello as she strode through the dark passages.

  Why is this still happening?

  Operator 47 checked his head to make sure that he still wasn’t wearing any of the VR gear that caused his brain to shift into stasis. No, this was a new kind of madness, a waking nightmare where he would be judged for his past actions. As he rounded a corner that now barely resembled a hallway, he spotted a door.

  Run… Run Roger Run, Operator 47 thought.

  He was going to reach that door even if it was the last thing he’d do.

  He lunged forward, his shoes slipping on the gelatinous floor that rippled beneath his weight. The door seemed to retreat with each step, stretching away like taffy in the warped space. His breath came in ragged gasps, fogging in the air that had grown suddenly cold despite the organic warmth emanating from the walls.

  You’re losing it, old boy!

  The slithering sound intensified, now accompanied by a rhythmic pulsing—like a massive heartbeat reverberating through the transformed structure. Operator 47 risked a glance over his shoulder and immediately wished he hadn’t. The corridor behind him was collapsing inward, not with debris and dust, but folding like flesh, the walls pressing together with wet, sucking sounds.

  Time to get the hell out of here!

  His fingers finally found the door handle, slick with some viscous substance he didn’t want to identify. He yanked it open and tumbled through, slamming it shut behind him. For a moment, blessed silence. Then he heard it—a voice, soft and melodious, coming from somewhere in the darkness ahead.

  “Roger... I’ve been waiting for you.”

  The voice sent ice through his veins. It couldn’t be. The person the voice belonged to had been dead for fifteen years. He’d seen her body, attended her funeral, and watched them lower the casket to the ground. But there was no mistaking that voice—Sarah’s voice, the same lilting tone that had once whispered promises in the dark.

  “You’re not real,” he rasped, pressing his back against the door. Something wet seeped through his tactical vest, and he could feel the door beginning to soften, to give way like rotting fruit.

  A figure crept toward him, casting shadows at strange angles, creating a menacing presence. But, there was something graceful about its movements. It wore Sarah’s face, but the eyes were wrong—too wide, too bright, reflecting light that didn’t exist in this suffocating darkness.

  “Real enough to remind you what you did,” the thing wearing Sarah’s face said, tilting its head at an angle that made Operator 47’s stomach lurch. “Real enough to collect what you owe.”

  The floor beneath him began to undulate. He stumbled forward, away from the dissolving door, deeper into whatever fresh hell awaited him. The Sarah-thing glided backward, maintaining the same distance, her feet never quite touching the ground.

  The story has been illicitly taken; should you find it on Amazon, report the infringement.

  "You know why I'm here," she continued, her voice carrying harmonics that shouldn't exist in a human throat. "You know what you took from me that night in Prague."

  Operator 47's mind raced, searching for the memory. Prague. The mission had been simple—eliminate the creator of the device. The same damned device that nearly got him killed many times over. But Sarah... Sarah had never been to Prague. She'd died in London, in their flat, from an aneurysm while he was halfway around the world chasing ghosts.

  "I was never in Prague with you," he managed, his voice steadier than his trembling hands. The walls around them pulsed faster now, synchronized with his accelerating heartbeat.

  The Sarah-thing laughed, a sound like breaking glass wrapped in silk. "Not that Prague, Roger. The other one. The one you've been trying so hard to forget."

  The floor suddenly gave way beneath his feet, but instead of falling, he found himself standing in a different room. Clinical white tiles, surgical instruments gleaming under harsh lights. The smell of antiseptic couldn't quite mask something else—copper and fear.

  "This is where you made your choice," the Sarah-thing whispered, now standing beside an operating table draped in plastic sheeting. "Where you decided that some secrets were worth more than love."

  Operator 47's throat constricted. The room spun, memories flooding back in fractured pieces—Sarah's voice, pleading.

  I’m so sorry my love.

  Surgical lights began to flicker, casting the room in alternating moments of blinding white and darkness. In the spaces between light and shadow, Operator 47 could see other figures moving—shapeless things that writhed and twisted at the edges of his vision.

  “You let him experiment on me,” Sarah said.

  The words hit him like a physical blow. Roger—Operator 47—staggered backward, his tactical training useless against the weight of buried memory.

  "No," he whispered, but even as the denial left his lips, images cascaded through his mind. The classified briefing. Malcolm Whitmore's name circled in red ink. The tech that needed to be acquired at any cost. And Sarah—brilliant, beautiful Sarah—who'd taken that research position at that facility without knowing what lurked in the sub-basements.

  Surgical instruments on a nearby tray began to rattle, then rise into the air, spinning lazily like metallic satellites. One scalpel caught the flickering light, its blade reflecting not steel but something organic, pulsing.

  "You knew what he was doing down there," the Sarah-thing continued, its form beginning to shift and blur at the edges. "You knew, and you still gave the order. Contain the breach. No witnesses."

  The surgical instruments on the nearby tray began to rattle, then rise into the air, spinning lazily like metallic satellites. One scalpel caught the flickering light, its blade reflecting not steel but something organic, pulsing.

  "I tried to get you out," Roger said, his voice breaking. "I sent the abort code. I tried—"

  "Tried?" The Sarah-thing's laughter turned shrill, inhuman. "You tried after Malcolm had already begun. After he'd injected me with his latest creation. After my cells had already started to... change."

  The room tilted, and Roger found himself on his knees, the white tiles cold and slick beneath his palms. The flickering lights revealed more tables now, dozens of them, each draped figure twitching in synchronization.

  "But you miscalculated, didn't you?" All the Sarah-things spoke in unison now.

  "The portal that opened contained a virus and it didn't die with me. It learned. It evolved. And it found its way back to him—to Malcolm."

  Roger's hands trembled against the cold tiles. The synchronous twitching of the draped figures intensified, creating a grotesque rhythm that matched his racing pulse. He forced himself to look up at the primary Sarah-thing, its features now flowing like wax under heat.

  "That's why the compound is changing," he breathed, understanding flooding through him like ice water. "Malcolm didn't create a new bioweapon. He's been infected this whole time,” Operator 47 said.

  The Sarah-thing's smile stretched impossibly wide. "Infected? Oh, Roger. He's not infected. He's become the perfect host. Fifteen years of slow integration, cell by cell, thought by thought. The man you've been hunting doesn't exist anymore."

  The surgical lights exploded in a shower of sparks, plunging the room into darkness. In the black, Roger could hear wet sounds—tearing, restructuring, growing. When a pale bioluminescence began to emanate from the walls themselves, he saw that the operating room had transformed into something else entirely. The tiles had become scales, the ceiling a ribbed cavity that expanded and contracted with each labored breath. He was inside something living.
