They stared down and said nothing for probably half a minute.
The pit had to be six hundred feet deep. Maybe deeper. Mercury lights every thirty feet or so lit up the descent. The stairs wound down in a squared spiral, following the shaft walls and leaving a wide-open drop in the middle. Seen from up here, that open space shrank to a tiny square by the time it reached the bottom. There was no way to discern the structure of what was down there—to know whether the shaft accessed a horizontal run, or did something else altogether.
The only visible detail was a soft red glow that shone onto the lowest flights of stairs, its source apparently somewhere off to the side. Its brightness waxed and waned in random patterns, and even its color seemed to vary within a narrow range: deep red for the most part, but for fleeting instants it seemed closer to neon pink.
Travis looked at the stair treads just beneath him. He followed them down and around through half a dozen flights. Each step had a layer of dust covering its ends, left and right, but was clear in the middle. They’d seen regular use.
“These stairs weren’t part of the mine’s original architecture,” Travis said. “Workers weren’t lugging tons of ore up sixty flights back in the day. The stairs were built later on, for Raines’s use. Power consumption and maintenance probably ruled out a lift, but a person could go up and down these all the time, with the right pacing. Take it slow, don’t kill yourself.” He paused. “Whatever Raines was doing to keep the Stargazer in check, it required him to go down there and deal with it directly.”
He didn’t need to finish the point aloud: the three of them would have to deal with it directly too.
“When we see it,” Paige said, “do you think it’ll be obvious what we’re supposed to do? Do you think we’ll just know?”
“Only one way to find out,” Bethany said.
But they didn’t go that minute. They did three things first, none of them difficult.
They searched the chamber for any kind of paperwork that might help. Maybe, by a long shot, the cheat sheet would turn up.
It didn’t. They checked the kitchen cabinets, the desk drawers, the space beneath the mattress, the vanity, even the couch cushions. Nothing.
Next they switched on the computer and Bethany scoured Raines’s files. There were hundreds of songs and audiobooks and movies and television shows that’d been downloaded from iTunes. The web browser’s history showed lots of visits to mainstream news sites, YouTube, and a scattering of blogs. There were very few document files on the computer—just instructions for various programs that’d probably come with the system. There was nothing about Tangent or Scalar or the Stargazer. Nothing useful at all.
The third thing they tried came to Travis as Bethany was reaching to shut off the computer.
“Hold up,” he said.
He followed the data cable with his eyes, up to where it punched through the ceiling.
“How does the system get online?” he said. “Cell transceiver, right?”
Bethany nodded. “It must be hidden up in the trees, like the surveillance cameras.”
Travis took his phone from his pocket and switched it on. As expected, there was no signal at all.
“Jeannie called me right before we came in off the slope,” he said. “She must’ve found out who lived downstairs in 1978.” He indicated the data line. “Is there any way to plug that into my phone? She might’ve left a voicemail.”
Bethany thought about it. She slid the computer’s case out from under the desk, pulled two thumb tabs and removed its side panel. She leaned close and scrutinized a card attached to the motherboard.
“No problem,” she said.
While she rigged the connection, Travis gazed at the wall of monitors. The contractors were still gathered near the squared tunnel that led into the hillside. Still pissed. One of them was on a phone, yelling at someone.
Travis noticed a few angles he’d overlooked before. They were interior shots of the tunnel right outside the green door, just resolvable through the gas cloud from the canisters. Other images showed an identical door that must be built into the second access—it was clear of gas, and no one stood outside it yet. Now as he watched, two men in ventilator masks made their way to the first door. Each had something in his hand, but through the haze the objects were impossible to identify at first. Then the men used them. The first held a tape measure. He pressed its tab into the gap on the hinged side, and walked the tape sideways until it stretched across the width of the door. The second man turned out to have a hammer, a standard-sized claw type. He rested an ear against the door and used the hammer to tap very lightly on the steel. Travis heard the tapping on this side, but only faintly. A few seconds later both men retreated back toward the stairs.
“We’re in business,” Bethany said.
