Zeke turned up the lantern’s wick to give himself as much light as possible.

He crossed the threshold, forcing himself past the line between mere night and someplace darker. His lantern filled the interior of the brick-lined, man-made cave with a wash of gold.

He’d meant to leave earlier, in the morning after his mother had gone to the Waterworks. But it’d taken all day to get his supplies together, and Rector had been difficult about the details.

So now it was almost dark outside, and perfectly dark inside.

The lantern cast a bubbled halo that carried him forward, into the unknown. He navigated the crumbled spots where the ceiling had dropped itself in pieces and piles; and he dodged the hanging tendrils of moss that was thicker than seaweed; and he ducked beneath the spiderwebs that dangled, waving, from brick to brick.

Here and there he saw signs of prior passage, but he didn’t know if he felt reassured that he was not the first to come this way. On the walls he saw black scuff marks where matches had been struck or cigarettes stubbed out; and he spied tiny, shapeless wads of wax that were too small to work as candles any longer. The initials W.L. were rubbed onto one cluster of bricks. Shards of broken glass glittered between weather-widened cracks.

All he could hear was the rhythmic tap of his footsteps, his muffled breaths, and the rusty hinge of the swinging lantern as it bounced back and forth.

And then there was another sound, one that made him think he was being followed.

He swung the lantern around, but saw no one. And there was no place for anyone to hide — it was a straight shot from the bricks where he stood to the beach. Forward, the way was less clear. As far as he could see, at the very edges of the lantern’s reach, nothing but more emptiness waited.

The grade rose. He was going up, very slightly. The open places above him where the bricks had come away did not show any sky because they were covered by earth. The echoes of the small sounds in the tunnel became more smothered and close. Zeke had expected it, but it made him more uncomfortable than he would’ve thought. He knew that the geography jerked up away from the coast, and that the exposed tunnel wormed a path underneath the city proper.

If Rector was right, at the end of the main pathway the route would split four ways. The leftmost one would lead up to the basement of a bakery. The roof of that building would be a semisafe place to get a handle on his surroundings.

Underground and in the dark, the way seemed to curve left, and then right. Zeke didn’t think he’d made a full circle, but he was definitely disoriented. He hoped that he’d still be able to pin down Denny Hill when he broke the surface.

After what felt like miles — but was surely only a fraction of that — the way widened and fractured as Rector had promised. Zeke took the hole on the far left and followed it another hundred feet before it terminated in a total dead end — or so he thought, until he backtracked slightly and found the secondary passage. This new corridor did not appear crafted, but dug. It did not look reinforced or secure. It looked temporary, spontaneous, and ready to fall.

He took it anyway.

The walls were more mud than stone or brick, and they were filthy wet. So was the floor, which was mostly a mash of decomposing sawdust, soil, and plant roots. It bit down on his boots and tried to hold him, but he slogged forward and finally, at the end of another twist and on the other side of another turn, he found a ladder.

With a skip and a jump he extricated himself from the gummy muck and seized the ladder hard. He lifted himself out and up, and into a basement so thickly dusted that even the mice and roaches left tracks on every surface. And there were footprints, too — quite a number of them.

At a rough glance he counted maybe ten sets of feet that had passed this way. He told himself that it was good, that he was glad to see that other people had survived the trip without trouble, but in truth it made him queasy. He’d hoped, and partly plotted, to find an empty city filled with mindless perils. Everybody knew about the rotters. Rector had told Zeke about the quiet societies that kept underground and out of sight, but mostly Zeke hoped to avoid them.

And, footprints… well…

Footprints implied he might run into other people at some point.

As he surveyed the room and determined that it held nothing of value, he resolved to be on his most careful behavior. While he climbed the stairs in the corner, he vowed to stick to the shadows and keep his head down, and his gun ready.

Really, he liked the thought of it. He enjoyed the prospect of being one boy against the universe, on a grand and dangerous adventure — even if it was only going to last a few hours. He would move like a thief in the night. He would be as invisible as a ghost.

On the first floor, all the windows were boarded and covered, reinforced and braced from corner to corner. A counter with a splintered glass cover rotted along the wall, and a set of old striped awnings lay forgotten in a pile. Stacks of rusting pans cluttered a broken-down sink, and a dilapidated cash box was scattered in pieces across the floor.

He found a ladder propped in an empty pantry. At the top of the ladder a trapdoor had been left unlocked. He pushed against it with his hand, his head, and his shoulder, and it opened away from him. In a moment, he was on the roof.

And then there was something cold and hard pressed against the back of his neck.

He froze, one foot still on the ladder’s top step.

“Hi there.”

Zeke replied, without turning around, “Hello yourself.” He tried to keep it low and growly, but he was scared and it came out at a higher pitch than he’d hoped for. In front of him he saw nothing but the corners of an empty rooftop; as far as the visor and his own peripheral vision could tell him, he was alone except for whomever was behind him with the very cold-barreled gun.

He set the lantern down with all the precision and caution he could muster.

“What are you doing up here, boy?”

He said, “Same as you, I reckon.”

“And what exactly do you think I’m doing?” his interrogator asked.

“Nothing you’d like to get caught at. Look, let me alone, will you? I don’t got any money or anything.” Zeke slowly stepped out of the hole, balancing carefully, with his hands held uselessly aloft.

The cold, circular chill of something hard and dangerous didn’t leave the exposed patch at the base of his skull.

“No money, eh?”

“Not a penny. Can I turn around? I feel stupid standing here like this. You can shoot me just as easy if I’m facing you. I’m not armed or nothing. Come on, let me loose. I didn’t do nothing to you.”

“Let me see your bag.”

Zeke said, “No.”

The pressure came harder against his neck. “Yes.”

“It’s just papers. Maps. Nothing worth anything. But I can show you something neat if you’ll let me.”

“Something neat?”

“Look,” Zeke said, trying to wriggle himself away by inches and not succeeding very well. “Look,” he said again, trying to buy time. “I’m a peace-abiding man, myself,” he exaggerated. “I keep Maynard’s peace. I keep it, and I don’t want any trouble.”

“You know a bit about Maynard, do you?”

“Well, I ought to,” he grumbled. “He was my granddad.”

“Get out,” said the voice behind him, and it sounded more honestly impressed than dubious. “No, you ain’t. I’d have heard about you, if you were.”

“No, it’s true. I can prove it. My mom, she was—”

The interrogator interrupted, “The Widow Blue? Now, come to think of it, she did have a boy, didn’t she?” He fell silent.

“Yeah. She had me.”

Zeke felt the cold circle against his neck slide, so he took a chance and stepped away — still keeping his hands in the air. He turned around slowly, and then dropped his hands with an exasperated yelp. “You were going to shoot me with a bottle?”
