Three hours later, we came upon the sign between two stone posts. It was metal, in the shape of an arrow, lying rusted on the ground beneath a cracked wood beam.
Big Country Secret Cavern, it read, in Jet Age 1950s script.
It was Joe Walke’s idea. If he wasn’t convinced by my story, he knew we were in danger when he spotted the man with the gun riding on the outside of the helicopter.
There was no way to drive out of the area without being spotted from the air, so Joe insisted we bail while he drew Haber and his men off in another direction. A former coal miner and also the son of a coal miner, he’d spent his whole life in the area and could navigate the woods blindfolded. Rosalind, too, knew a special way out on foot.
“This place was big a long time ago, but it’s been closed for years. Even the road is gone,” Rosalind said as we stepped past the sign, Roxie at our heels.
In the low moonlight, I saw that there was an indentation in the hill we’d been skirting. It was just rock face along this side, ten stories of it going straight up.
Twenty feet later, we saw the cave opening. It was triangular, like a church roof, and it was on the other side of a huge black pond.
“How are we going to get through? Swim? It’s filled with water.”
“No, this way,” Rosalind said, going left around the oblong pond. “They used to send you through in paddle boats, Tunnel of Love–style, Grandpa said, but there’s a walkway. C’mon.”
As we stepped in under the cathedral-like ceiling, Roxie started barking.
“Stop your fidgeting, Roxie. I like it as much as you do.”
I turned on one of the flashlights Joe Walke had given us. We also had some water bottles, and the shotguns—they held about twenty rounds, most of them number 7 birdshot, but there were a few shells of double-ought buck.
What wasn’t in our favor was that the shotguns were over-and-under break-open style, so they could only hold two rounds at a time. If we got into a firefight with these professional military folks, it was going to be over very quickly.
The beam of the flashlight revealed some beer bottles and graffiti on the rough rock wall, but they looked old and faded. I pointed the flashlight down the cement lip of the path beside the canal-like waterway. The path continued for at least a football field and then seemed to disappear to the right.
“You sure the other side isn’t blocked or anything?” I asked.
“No way. The other side is even more open than this one. It would take an earthquake,” Rosalind said.
We walked deeper into the eerie, dead-silent cave. The rough rock walls had a lunar quality, seeming to shift as the light moved over them. Some sections had weird patterns and folds. Embedded minerals in other areas glittered and threw back the light in disco-ball constellations.
Even on a day when I’d had a gun to my head, in this claustrophobic space my nerves ached to turn around. It was like we’d just walked in through the gates of hell.
“Marshall, Will, and Holly, on a routine expedition,” I sang, as I pointed the light up at cone-shaped rock stalagmites—or were they stalactites? It had been a while since I’d been underground, in the middle of nowhere, in the middle of the night.
“What’s that?” Rosalind asked.
“From a show I used to watch when I was your age called Land of the Lost. Ever hear of it?” I asked.
“No,” she said, leading onward into the dark. “We don’t have a TV. Grandpa says TV makes people stupid.”
“He may be onto something there,” I said. What a brave and capable little girl.
We finally reached the opening. When we stepped into the glorious open air from the long and nightmarish tunnel, I saw that the canal led into a huge lake. We were on the other side of the hill now. We’d walked straight through the mountain.
I looked back. The roof of the tunnel was an almost perfectly rectangular slab of rock about ten feet thick. It looked like a knocked-over monolith, like the roof of Stonehenge half-buried in the earth.
“People actually paid to do that?” I said.
“So I’m told,” Rosalind said, shaking her head.
“How long is it to this town? What’s it called?”
“Chapman. About eight miles around the other side of this lake.”
“Wait! Get down!” I said. “I see something.”
About a mile away, along the left shore of the lake, there was a light. A flashlight. Somebody walking, coming toward us. Worse than that, I thought I heard a short bark.
“You gotta be kidding me,” I mumbled. What are we going to do now?
I looked back at the mouth of the cavern, then toward the slope of the hill above it. It was steep, filled with trees, but manageable.
“But that heads right back up the hill to their camp,” Rosalind whispered. “Don’t we want to go away from there?”
“We have no choice. C’mon,” I whispered, and slung the shotgun over my shoulder.
