They Had to Find Something
Christopher couldn't tell whether minutes or hours had passed since the police went into the mine, but it had grown dark, and he'd begun to shiver. Finally, he saw the beacon of their flashlights against the trees. The officers exited the mine in a row, all looking worse for wear; one was clutching her head.
Toxic Mine
To Christopher's dismay, the police had found the metal chains, but there was no door, and most certainly no dead body. According to the police, Christopher had hallucinated his experience as a result of the noxious gases inside of the mine, which had been undisturbed for years. They warned him to stay away from the mine and seek medical attention immediately.
