Book excerpt: Beneath the Neon: Life and Death in the Tunnels of Las Vegas chronicles O’Brien’s adventures in subterranean Las Vegas. He follows the footsteps of a psycho killer. He braces against a raging flood. He parties with naked crackheads. He learns how to make meth, that art is most beautiful where it’s least expected, that in many ways, he prefers underground Las Vegas to aboveground Las Vegas, and that there are no pots of gold under the neon rainbow.
