Camp Verity had been shut for nineteen years. The cabins smelled like wet paper and the dock sagged under your feet. Mara set the recorder on a tree stump while Devon clipped on the mics and Priya filmed the dead waterfront of Signal Lake. "Episode one," Mara said. "Why does a whole town pretend this place never existed?" Then they noticed something weird. When Priya yelled across the water, the lake gave back no echo at all.

Mara decided to test the echo thing properly. She clapped, shouted, and banged a paddle on the dock. Nothing came back. "That's not normal," Devon said, checking his audio levels. The waveform showed their voices, then flat silence where the bounce should be. "Something here is eating sound," he whispered.

Priya backed away from the dock and tripped over a rusted speaker bolted to a post. Wires ran from it into the ground, toward the lake. "It's a sound system," she said. "The whole shoreline is wired." Someone, long ago, had set this place up to kill every echo on purpose.

Priya traced the wires to a locked shed. The door was old and the lock snapped easily. Inside sat a dusty mixing board and a reel of tape labeled SESSION SIX. "Somebody recorded what happened," she said. "And buried the proof out here so no one would ever hear it."
