Reliquary

Snow looked up. Between the blackened girders of the bridge, he could see the burnt facades of buildings. A thousand dirty windows stared down at the dead river. Too bad, he thought, the messenger had to throw it into the Humboldt Kill, aka Cloaca Maxima, named after the great central sewer of ancient Rome. The Cloaca was so called because of its centuries-old accumulation of shit, toxic sludge, dead animals, and PCBs. A subway lumbered by above, shuddering and screeching. Beneath his feet the boat quivered, and the surface of the glistening thick water seemed to jiggle slightly, like gelatin that had begun to set.

“Okay, men,” he heard the Sergeant say. “Let’s get wet.”

Snow busied himself with his suit. He knew he was a first-rate diver. Growing up in Portsmouth, practically living in the Piscataqua River, he’d saved a couple of lives over the years. Later, in the Sea of Cortez, he’d hunted shark, done technical diving below two hundred feet. Even so, he wasn’t looking forward to this particular dip.

Though Snow had never been near it before, the team talked about the Cloaca often enough back at the base. Of all the foul places to dive in New York City, the Cloaca was the worst: worse than the Arthur Kill, Hell Gate, even the Gowanus Canal. Once, he’d heard, it had been a sizeable tributary of the Hudson, cutting through Manhattan just south of Harlem’s Sugar Hill. But centuries of sewage, commercial construction, and neglect had turned it into a stagnant, unmoving ribbon of filth: a liquid trash can for everything imaginable.

Snow waited his turn to retrieve his oxygen tanks from the stainless-steel rack, then stepped toward the stern, shrugging them over his shoulders. He still was not used to the heavy, constricting feel of the dry suit. Out of the corner of his eye, he could see the Sergeant approaching.

“All set?” came the quiet baritone.

“I think so, sir,” Snow said. “What about the headlamps?”

The Sergeant stared at him blankly.

“These buildings cut out all the sunlight. We’ll need lamps if we’re going to see anything, right?”

The Sergeant gri

He looked at Snow appraisingly, hesitating a moment. “Listen,” he said in a low voice. “This won’t be like those practice dives in the Hudson. I only brought you along because Cooney and Schultz are still in the hospital.”

Snow nodded. The two divers each had gotten a case of the “blastos”—blastomycosis, a fungal infection that attacked the solid organs—while searching for a bullet-ridden body in a limo at the bottom of the North River the week before. Even with mandatory weekly blood work to screen for parasites, bizarre diseases ruined the health of divers every year.

“If you’d rather sit this one out, it’s okay,” the Sergeant continued. “You can stay here on deck, help with the guide ropes.”

Snow looked over at the other divers as they strapped on their weight belts, snugged the zippers of their dry suits tight, let the lines over the sides. He remembered the first rule of the Scuba team: Every man dives. Fernandez, making a line fast to a cleat, looked back toward them and smirked knowingly.

“I’m diving, sir,” Snow said.

The Sergeant stared at him for another long moment. “Remember basic training. Pace yourself. First time down in that muck, divers have a tendency to hold their breath. Don’t do it; that’s the fastest way to an embolism. Don’t overinflate your suit. And, for Christ’s sake, don’t let go of the rope. In the mud, you forget which way is up. Lose the rope, and the next body we come looking for will be yours.”

He pointed to the sternmost guide rope. “That’ll be you.”

Snow waited, slowing his breathing, while the mask was slipped over his head and the lines attached. Then, after a final check, he went over the side.

Even through the stifling, constrictive dry suit, the water felt strange. Viscous and syrupy, it didn’t rush past his ears or eddy between his fingers. Pushing against it was an effort, like swimming in crankcase oil.

Tightening his grip on the guide rope, he allowed himself to sink a few feet below the surface. Already the keel of the launch was invisible overhead, swallowed by a miasma of tiny particles that filled the fluid around him. He looked around through the feeble, greenish light. Immediately in front of his face, he could see his gloved hand gripping the rope. At a greater distance, he could make out his other hand, outstretched, probing the water. An infinity of motes hung in the space between. He could not see below his feet: there was only blackness. Twenty feet down into that blackness, he knew, lay the ceiling of a different world: a world of thick, encasing mud.

For the first time in his life, Snow realized just how much he had depended on sunlight and clean water for his sense of security. Even at fifty meters down, the waters in the Sea of Cortez had been clear; light from his torch had given a sense of ope

Suddenly, at the outermost reaches of his vision, he saw or thought he saw through the dim currents a solid haze beneath him, an undulating, veined surface. It was the layer of silt. He sank toward it slowly, feeling a knot of apprehension grow in his stomach. The Sergeant had said that divers often imagined they saw odd things in the thick waters. It was sometimes hard to tell what was real and what was not.

His foot touched the strange floating surface—passed through it—and instantaneously a cloud roiled out, folding around him, shutting out all sight. Snow panicked for an instant, scrabbling at the guide rope. Steadying himself with the thought of sniggering Fernandez, he descended. Each movement sent a new storm of black liquid eddying against his visor. He found himself instinctively holding his breath against it, and he forced himself to breathe long, regular breaths. This is bullshit, he thought. My first real dive on the force, and I’m practically a basket case. He stopped for a moment, controlling his breathing, forcing it back into a steady rhythm.

He let himself down the rope a few feet at a time, moving sparingly, trying to relax. With some surprise, he realized that it no longer mattered whether his eyes were open or shut. His mind kept returning to the thick mantle of mud that waited beneath him. Things were in that mud, encased, like insects in amber…

Suddenly, his boots seemed to touch bottom. But it was unlike any seabed Snow had felt before. This bottom seemed to be decomposing; it yielded beneath his weight with a disgusting kind of rubbery resistance, sneaking up his ankles, then his knees, then his chest, like sinking into clammy quicksand. In a moment it was over his head, and he was beneath it and still descending, slower now, encased wholly in an ooze that could not be seen but only felt, pushing close against the neoprene of his dry suit. He could hear the bubbles of his own exhalations working their way upwards around him; not with the quick abandon he was used to, but instead with a slow flatulent rolling. The mud seemed to offer more resistance as he descended. How far down was he supposed to go in this shit?

He swung his free hand about as he had been taught, sweeping it through the muck. It bumped into things. In the blackness with his thick gloves it was hard to tell what they were: limbs of trees, crankshafts, nasty snarls of wire, the collected waste of centuries trapped in this graveyard of mud.
