Michael Connelly said this quote

The Strip was still lit by a million neon lights, though the crowds on the sidewalk had greatly decreased by this hour. Still, Bosch was awed by the spectacle of light. In every imaginable color and configuration, it was a megawatt funnel of enticement to greed that burned twenty-four hours a day. Bosch felt the same attraction that all the other grinders felt tug at them. Las Vegas was like one of the hookers on Sunset Boulevard in Hollywood. Even happily married men at least glanced their way, if only for a second, just to get an idea what was out there, maybe give them something to think about. Las Vegas was like that. There was a visceral attraction here. The bold promise of money and sex. But the first was a broken promise, a mirage, and the second was fraught with danger, expense, physical and mental risk. It was where the real gambling took place in this town.
