Around 2:00 a.m., Ludlam decided to call it a night. He began retracing his steps, heading back to where he’d come down. The sewer was cold, and mist swirled in the beam from his flashlight. Something brushed against his foot, swimming through the fetid water. So far, he’d been lucky—nothing had bit him yet.
It was crazy to be down here—Ludlam knew that. But he couldn’t give up. Hell, he’d patiently sifted through sand and gravel for years. Was this really that different?
The smell hit him again. Funny how he could ignore it for hours at a time, then suddenly be overpowered by it. He reached up with his left hand, pinched his nostrils shut, and began breathing through his mouth.
Ludlam walked on, keeping his flashlight trained on the ground just a few feet in front of him. As he got closer to his starting point, he tilted the beam up and scanned the area ahead.
His heart skipped a beat.
A dark figure was blocking his way.
“What the hell are you doing down here?” said the man blocking Ludlam’s way. He was wearing a stained Sanitation Department jacket.
“I’m Dr. David Ludlam,” said Ludlam. “I’ve got permission.” He reached into his raincoat’s pocket and pulled out the letter he always carried with him.
The sanitation worker took it and used his own flashlight to read it over. “‘Garbologist,’” he said with a snort. “Never heard of it.”
“They give a course in it at Columbia,” said Ludlam. That much was true, but Ludlam wasn’t a garbologist. When he’d first approached the City government, he’d used a fake business card— amazing what you could do these days with a laser printer.
“Well, be careful,” said the man. “The sewers are dangerous. A guy I know got a hunk taken out of him by an alligator.”
“Oh, come on,” said Ludlam, perfectly serious. “There aren’t any gators down here.”
