"My uncle's in maintenance," Nogales said with a little pride. "He lets me use his key to come up here." He opened a key and stepped onto the roof of Circus Circus's west tower. While the others followed, he set up a telescope.

"Oh!" said Little Rock. "Do you look at the stars?"

"No, too bright," he said. "I watch the city." He pointed at a column of light to the south. "That's my reference point- Luxor. It's practically next door to the airport. When the Enfermedad hit, that whole end of the Strip was wiped out. Not just fires, but gas explosions, plane crashes, even bombs... but somehow, at the end of it, Luxor was still standing, and the light's still running."

He shifted the telescope to a closer point, a building at least 60 stories high a few blocks off the Boulevard. "That is Trump Tower. It's the second tallest building in Vegas that's still standing and complete. The only one taller is Stratosphere, and that's strictly an observation tower."

Little Rock peered through the telescope. "So, what's special about it?"

"Because," he said, adjusting the telescope, "there's lights on."

"Huh," she said, then shrugged. "But what does that mean? Lights go on and off all the time."

"But that's a light in a suite. And it's on every night."

Columbus motioned Little Rock aside. Looking closely, he said, "Curtains are drawn... and there's no movement... and no lights in the other rooms. It's almost certainly just a light on a timer."

"Maybe so," Nogales said. "But some people are sure they have seen shadows on the curtain. Even if there's nobody living in there, somebody had to set the light to go on, for a reason. Maybe it's to lead people to the room. And what's inside?" Columbus nodded thoughtfully, then looked to Tal.

"Has anyone tried to search the hotel?"

Tal laughed. "Hunting parties go through there all the time, but no one's gone above the third floor. That building is next door to the biggest mall in Vegas. One light fifty floors up is the least of their concerns."

"Yeah, still, it could be a survivor."

"That's what most of us think," Nogales interjected excitedly. "A lot of people say it could be Donald Trump. There have been sightings, in the day... He could be going out by day disguised as a zombie, then hiding in the tower at night... But who knows if he stayed sane? He might be like that guy, you know, Leo DiCaprio played... Hughes! Or in that story about the vampires, that they made that lousy Will Smith movie about, hiding by night, and hunting by day... Only, maybe he doesn't just hunt zombies..." Little Rock's eyes widened. Wichita smiled.

"So... Is there anything else?" the girl said.

"Oh, yeah," said Nogales, now in high storytelling gear. "Have you ever heard of... Mothman?"

Little Rock's expression went from curious to quizzical. Wichita sputtered and then burst into open laughter. "Mothman? What's that? And what would he do, fly into the Luxor lamp?"

"Hey," said Columbus, "I think Mothman's scary!" His wife leaned against the wall and continued to laugh. The others soon joined in the mirth. Nogales looked upset, but Columbus turned his head. In the murk of too-bright, too-few lights to the east, he heard a low hum, and for a moment he thought he glimpsed a shape flit among the buildings.
