“Cost a fortune to build. And not all of it came from the pockets of the oil barons. They called in favors from City Hall.” Diamond tapped the side of his nose. “That kind of construction you don’t document.”
“Why were they abandoned?”
“Impossible to maintain. Beneath most of the sewer and storm drains like they were, you could never keep them dry. Then there was methane buildup, carbon monoxide buildup, you name it.”
Pendergast nodded. “Heavy gases, seeking the lowest level.”
“They spent millions on those damn tunnels. Never finished the line. They were only open for two years before the flood of ninety-eight overwhelmed the pumps and half-filled everything with sewage. So they bricked everything up. Didn’t even pull out the machinery or nothing.”
Diamond fell silent, and the chamber filled once again with the roar of the vent stack.
“Are there any maps of these tunnels?” Pendergast asked after a moment.
Diamond rolled his eyes. “Maps? I looked for maps for twenty years. Those maps don’t exist. I learned what I learned by talking to a few old-timers.”
“Have you been down there?” Pendergast asked.
Diamond twitched noticeably. Then, after a long moment, he nodded silently.
“Could you diagram them for me?”
Diamond was silent.
Pendergast moved closer. “Any little thing you could do would be appreciated.” His hand seemed merely to smooth the lapel of his jacket, but suddenly a hundred-dollar bill flared between two of the slender fingers, arching in the engineer’s direction.
Diamond stared at the bill, as if deliberating. Finally, he took it, rolled it into a ball, and crammed it into a pocket. Then, turning to the drafting table, he began sketching deftly on a piece of yellow graph paper. An intricate system of tunnels began to take shape.
“Best I can do,” he said, straightening up after a few minutes. “That’s the approach I used to get inside. A lot of the stuff south of the Park has been filled with concrete, and the tunnels to the north collapsed years ago. You’ll have to find your way down to the Bottleneck first. Take Feeder Tunnel 18 down from where it intersects the old ’Twenty-four water main.”
“The Bottleneck?” Pendergast asked.
Diamond nodded, scratching his nose with a dirty finger. “There’s a vein of granite running through the bedrock deep beneath the Park. Super hard stuff. To save time and dynamite, the old pipe jockeys just blasted one massive hole in it and funneled everything through. The Astor Tunnels are directly below. As far as I know, that’s the only way to get inside them from the south—unless you got a wet suit, of course.”
Pendergast accepted the paper, looking it over carefully. “Thank you, Mr. Diamond. Is there any chance you’d be willing to return and make a more careful survey of the Devil’s Attic? For adequate remuneration, of course.”
Diamond took a long drink from the flask. “All the money in the world wouldn’t get me down there again.”
Pendergast inclined his head.
“Another thing,” Diamond said. “Don’t call it the Devil’s Attic, all right? That’s mole talk. They’re the Astor Tunnels.”
“Astor Tunnels?”
“Yeah. They were Mrs. Astor’s idea. The story goes that she got her husband to build the first private station beneath her Fifth Avenue mansion. That’s how it all got started.”
“Where did the name ‘Devil’s Attic’ come from?” Pendergast asked.
Diamond grinned mirthlessly. “I don’t know. But think about it. Imagine tunnels thirty stories underground. Walls tiled in big murals. Imagine waiting rooms, stuffed to the gills with mirrors, sofas, fancy stained glass. Imagine hydraulic elevators with parquet flooring and velvet curtains. Now think of what all that would look like after being doused in raw sewage, then sealed up for a century.” He sat back and stared at Pendergast. “I don’t know about you. But to me, it would look like the attic of Hell itself.”
THE WEST SIDE railyard lay in a wide depression on the westernmost reaches of Manhattan, out of sight and practically invisible to the millions of New Yorkers who lived and worked nearby, its seventy-four acres the largest piece of undeveloped land on the island outside Central Park. Once a bustling hub of turn-of-the-century commerce, the railyard now lay fallow: rusted tracks sunken among burdock and ailanthus trees, ancient sidings rotting and forgotten, abandoned warehouses sagging and covered with graffiti.
For twenty years the piece of ground had been the subject of development plans, lawsuits, political manipulations, and bankruptcies. The tenants of the warehouses had gradually abandoned their leases and left, to be replaced by vandals, arsonists, and the homeless. In one corner of the railyard lay a small, bedraggled shantytown of plywood, cardboard, and tin. Alongside were a few pathetic kitchen gardens of straggly peas and squash run riot.
Margo stood amidst a plot of fire-scorched piles of rubble, sandwiched between two abandoned railyard buildings. The warehouse occupying the plot had burned four months earlier, and it had burned hotly and thoroughly. The structure had been reduced to a blackened I-beam framework and some low cinder-block stem walls. Beneath her feet, the cement pad was hip deep in rubble and burned shingles. The remains of several long metal tables stood in one corner of the lot, covered with smashed equipment and melted glass. She looked around, peering through the late afternoon shadows that knitted themselves across the sunken ground. There were several hulks that had once been large machines, housed in metal cabinets; the cabinets had melted and the inner workings lay exposed, masses of twisted wire and ruined circuit boards. The acrid stench of burned plastic and tar clung stubbornly to everything.
