Reliquary

The struggle seemed to have exhausted Smithback, and he sagged forward. “What are you doing here?” he asked at last.

“I might ask you the same question,” Pendergast replied. “Mephisto is leading us to the Astor Tunnels—the Devil’s Attic. There was a plan to drain the Reservoir and flood the creatures out.”

“Captain Waxie’s plan,” D’Agosta added.

“But the Reservoir is full of the Mbwun lily. That’s where the creatures were growing it. And we can’t allow the plants to reach the open ocean. It’s too late to stop the water dump, so a SEAL team was sent in from the river to seal the lowest spillway tunnels below. We’re going to seal off the spaces above the Astor Tunnels to prevent any spillages. We’ll bottle up the flow, keep it from escaping down into the river. If we succeed, it will back up to the Bottleneck here, but nowhere else.”

Smithback remained unspeaking, his head bowed.

“We’re well armed, and fully prepared for whatever’s down there. We have maps. You’ll be safer with us. Do you understand, William?”

Margo watched as Pendergast’s mellifluous delivery worked its calming effect. Smithback’s breathing seemed to slow, and finally he nodded almost imperceptibly.

“So what were you up to, anyway?” D’Agosta asked.

Pendergast made a restraining motion with one hand, but Smithback looked in the direction of the Lieutenant. “I followed Captain Waxie and a group of policemen underneath the Reservoir,” he said quietly. “They were trying to shut off some valves. But they’d been sabotaged, or something. Then—” He stopped abruptly. “Then they came.”

“Bill, don’t,” Margo interjected.

“I ran away,” Smithback said, swallowing hard. “Duffy and I ran away. But they caught him in the gauging station. They—”

“That’s enough,” said Pendergast quietly. There was a silence. “Sabotage, did you say?”

Smithback nodded. “I heard Duffy say that somebody had been messing with the valves.”

“That is troublesome. Troublesome indeed.” There was a look on Pendergast’s face that Margo had not seen before. “We’d better continue,” he said, shouldering the flamethrower again. “This Bottleneck is a perfect place for an ambush.” He glanced around the dark tunnel. “Mephisto?”he whispered.

There was a stirring in the darkness, then Mephisto came forward, arms folded across his chest, a wide smirk on his whiskered lips.

“I was just enjoying this touching reunion,” he said, in his silky hiss. “Now the merry band of adventurers is complete. Ho, scriblerian! I see you’ve descended farther than you dared venture on our first meeting. Grows on you, doesn’t it?”

“Not especially,” Smithback replied in a low voice.

“How nice, at least, to have one’s own Boswell at hand.” In the artificial light of the goggles, it seemed to Margo that Mephisto’s eyes glittered gold and crimson as they surveyed the group. “Will you compose an epic poem on the event? The Mephistiad. In heroic couplets, please. That’s assuming you live to tell the tale. I wonder which of us will survive, and which will leave their whitened bones to lie here, forever, in the tunnels beneath Manhattan?”

“Let’s move on,” Pendergast said.

“I see. Whitey here feels there has been enough talk. Perhaps he fears it will be his bones left to the rats.”

“We need to set several series of charges directly below the Bottleneck,” Pendergast said smoothly. “If we stand here listening to your empty posturing, we won’t have time to exit before the Reservoir dumps. Then it will be your bones, as well as mine, that are left for the rats.”

“Very well, very well!” Mephisto said. “Don’t chafe.” He turned and began clambering down a large, dark tube.

“No,” Smithback said.

D’Agosta took a step toward the journalist. “Come on. I’ll take your hand.”

The vertical tube ended in a high-ceilinged tunnel, and they waited in the darkness while Pendergast set several sets of charges, then motioned them on. A few hundred yards down the tunnel, they arrived at a walkway that crossed a few feet above the level of the water. Margo felt grateful; the ankle-deep stream had been cold and foul.

“Well!” whispered Mephisto, climbing on the walkway. “Perhaps the Mayor of Grant’s Tomb can finally dry out his wingtips.”

“Perhaps the Hobo King can finally shut up,” D’Agosta growled.

A delighted hiss came from Mephisto. “Hobo King. Charming. Perhaps I should go hunting track rabbits and leave you to do your own spelunking.”

D’Agosta stiffened but held his tongue, and Mephisto led the way across the walkway into a crawl space beyond. Margo heard the roar of falling water in the distance, and soon the passage ended at a narrow waterfall. A narrow iron ladder, almost concealed by the ordure of many decades, descended into a vertical tunnel at the base of the falls.

They passed through the tunnel one at a time, dropping to an irregular bedrock floor beneath the confluence of two seventy-two-inch mains. The narrow boreholes of explosive drills lined the walls like the work of disorderly termites.

“Nous sommes arrives,” said Mephisto, and for the first time Margo thought she could detect nervousness behind the bluster. “The Devil’s Attic is directly beneath us.”
