“Everyone cover your ears,” he said, and brought his assault rifle to his shoulder. The crack of the shot was especially brutal in the tight confines.
The bullet had knocked free a splinter of the ceiling. He retrieved it, looked at it for only a moment, and tossed it to Mark Murphy.
“Completely solidified,” he commented. “When the cave below the pit collapsed it left them hanging.”
“Of course,” Alana said, examining the material.
“Little help for the nonscience types.” Linda didn’t bother looking at the rock sample. Her only exposure to geology was a “rocks for jocks” class back in college.
“Above us is the bottom of a tar pit,” Eric answered, “like La Brea in L.A., only smaller and obviously dormant.”
“It’s actually asphaltic sand,” Alana corrected.
“During the summer months, it warmed enough to get sticky and entrap the animals. My guess is, the people were thrown in as a form of execution. Then, at some point over the past two hundred years, the bottom of the pit collapsed—that’s all this rubble on the floor—and exposed the victims at the very deepest part of the pit.”
“There was something I was told by St. Julian Perlmutter a couple of days after our initial meeting,” Alana said, suddenly remembering. “He’d come across one additional scrap of information. It comes from a local belief about Al-Jama’s tomb. It is said he was buried beneath the ‘black that burns.’ That’s why they had us digging in an abandoned coal mine. The terrorists thought the black was coal, but it was this.”
Eric took the shard of hardened tar from her and held the flame of a disposable lighter to the thumb-sized lump. In seconds, it caught fire, and he dropped it to the ground. The four of them watched it burn silently.
Linda snuffed it out with her foot. “I would say we’re getting close.”
But another hour of exploration still hadn’t revealed the hidden tomb.
Eric and Mark had separated from the women at yet another juncture. They approached the dead end of a particularly straight and easy section of tunnel deep under the river’s original water level. Eric paused to take a sip from his canteen before they retreated to the rendezvous. The end of the tunnel sloped up in a perfectly flat ramp that met the ceiling. Something about it intrigued him, and he climbed up the incline until his face was inches from where it joined the roof.
Rather than solid rock, he saw a jagged line, a crack barely a millimeter wide, that ran the full width of the tunnel. He fumbled in his pocket for the disposable lighter, and called over his shoulder, “Kill your light.”
“What? Why?”
“Just do it already.”
He thumbed the lighter and held the flame close to the crack. There wasn’t much of a flicker, but it was enough to convince him that there was an open space on the other side of the ramp and a slight breeze was getting through. He turned on his light again, examining every square inch of the incline. It was a neatly fitted piece of work. The cracks along the walls were almost invisible.
“This is man-made,” he announced. “I think it’s like a giant teeter-totter. Give me a hand.”
They stood, stooped, as far up the ramp as they could go, with their backs braced against the ceiling.
“On three,” Eric said. “One . . . two . . . three.”
They pushed with everything they had. At first, nothing happened, and the sounds of their straining bodies filled the tunnel. Then, imperceptibly, the floor under them gave way slightly, pushed down by their combined strength. When they relaxed, it snapped back into position.
“Again. Harder.”
Their second attempt pushed the big stone lever down about an inch, enough for Eric to see there was a large chamber beyond. He jammed the lighter into the crack just before they let go, but the weight of stone was too great and the plastic case was crushed.
“Good idea, though. I think the four of us should be able to do it. There’s enough room to stand side by side.”
They found Linda and Alana a few minutes later, sitting with their backs against a wall sharing a protein bar.
“Not to keep repeating myself,” Linda said around a monstrous bite, “but we hit another dead end.”
“Eric and I think we found something.”
Moments later, Eric explained how the rock incline was a pivoting device, balanced in the middle, halfway up the ten-foot-high slope. The four got into position at the top of the ramp, standing side by side, their upper shoulders pressed to the ceiling.
“And go,” Linda ordered.
Their combined strength made stone grate against stone, and the incline began to flatten out. What had been a tiny crack yawned into the entrance of another chamber, one they could see was partially lined with mud bricks. Harder they pushed, groaning at the effort. The lever dipped on its fulcrum, so the ramp became perfectly flat.
“You know once we’re through, there’s no going back,” Linda grunted, fresh perspiration flushing her pixie face.
“I know,” Mark replied. “Push.”
The rock platform began to slope down into the bricked chamber beyond the tunnel, and they were able to shuffle back so they stood at its very lip, muscles quivering. They were only a couple feet above the sand-covered floor.
Linda judged they had enough clearance. “Ready? Go!”
