“Hold on a second,” the man replied. He stepped over and opened the thick door to the ancient safe. He rummaged around a wooden bin inside, then turned and tossed something to Pitt. It was a tiny smooth stone, silvery white in color.

“Black Kobluna?” he asked.

“A sample on the house, so that you know what we’ve been talking about.”

Pitt reached across the counter and shook hands with the geologist, thanking him for his time.

“One more thing,” the old man said, as Pitt strolled toward the door. “You run into that Booth fellow, you be sure and tell him I’m coming after him with a pickax if I ever see him again.”

The afternoon had turned colder under the cast of an approaching front, and Pitt waited anxiously for the car heater to warm up as he exited the Co-op’s parking lot. Grabbing a quick lunch at a café in Blind River, he drove back through the winding mountain road toward the airport, contemplating the Inuit ruthenium tale. The ore had to have come from the Arctic, presumably near the Inuit camp at Adelaide. How had the Inuit, with primitive technology, mined the ruthenium? Were there still significant reserves in place? And who was John Booth and why was he interested in the Inuit ore?

The questions brought no answers as he wound through the scenic hills, braking as he pulled up behind a slower-moving RV. Reaching a straight stretch in the road, the RV driver pulled to the shoulder and waved for Pitt to pass. Pitt stomped on the accelerator and sped past the motor home, which he noted had a Colorado license plate.

The road snaked sharply ahead of him, the two lanes carving into the edge of a rocky mountainside that tumbled down to a river below. Twisting through a tight bend, Pitt could see the roadway a mile ahead, where the highway nearly doubled back on a parallel facing. He caught a glimpse of a white sedan parked in a turnout. It was the same vehicle that John Booth had climbed into at the Co-op. Pitt lost sight of the car as the roadway bent and twisted once more.

Rounding through a tight S curve, the road straightened again for a short stretch. To Pitt’s left, the hillside plunged in a steep drop-off, falling several hundred feet to the river below. As his rental car gained speed on the straightaway, Pitt heard a faint pop, like the burst of a distant Fourth of July firework. He glanced ahead but noticed nothing, as a deep rumble followed the initial noise. A movement caught his eye, and he looked up to see a house-sized boulder sliding down the mountainside above him. The huge rock was falling in a perfect trajectory to intersect with Pitt’s car two hundred feet down the road.
