"I doubt if I could bring myself to shoot another human," Ambrose protested, but his voice came with a cold edge.

"Don't look upon these guys as human. They're cold-blooded executioners who could slit a woman's throat and eat ice cream afterward. I warn you, Doc, if he looks cross-eyed at you, brain him with a rock."

The Suzukis were still idling in neutral, and it took them less than a minute to figure out the shift, brake, and throttle controls. With a farewell wave to Ambrose, Pitt roared off first. There was no room for the machines to move between the outer rails and the walls of the tunnel, not without scraping the handgrips on the rough granite. Pitt kept his wheels in the center of the rail tracks, closely followed by Pat and Marquez. Bouncing over the rail ties with rigid suspensions rattled their teeth and made for uncomfortable riding. Pat felt as if her insides were being shaken around by a laundromat dryer. Pitt found the trick was to find the proper speed that gave the least vibration. It worked out to twenty-five miles an hour, a speed that might have seemed slow and safe on a paved road but was quite dangerous inside a narrow mine tunnel.

The hard-rock acoustics made the exhaust blast echo in their ears. The beams from the headlights hopped up and down, striking the rails and overhead timbers like strobe lights. He narrowly missed an ore car that was sitting on the tracks and partially protruding from an intersecting tunnel. After riding up the gentle grade of a lift shaft, they reached the upper level to a mine that was labeled "The Citizen" on Pitt's directional computer. Pitt rolled to a stop where the tunnel met another at a fork and consulted the tiny monitor.

"Are we lost?" Pat queried above the rattle from the exhaust pipes.

"Another two hundred yards down the tunnel on the left and we should come to the end of the mine tunnel you said comes out under the New Sheridan Hotel."

"The entrance to the O'Reilly Claim was covered over a hundred years ago," said Marquez. "We'll never get out that way."

"Never hurts to look," said Pitt, shifting gears and easing the clutch on the Suzuki. He gave the bike a burst of speed and was forced to brake hard within two minutes, when he suddenly confronted a brick wall that solidly blocked the old mine entrance. He came to an abrupt stop, leaned the bike against a timber, and studied the bricks under the headlight.

"We'll have to find another way," said Marquez, as he pulled alongside, came to a stop, and set both feet on the ground to keep the bike upright. "We've come out at the basement foundation wall of the hotel."

Pitt appeared not to have heard him. As if his mind was a thousand miles away, he slowly reached out and ran his hand over the old kiln dried red bricks. He turned as Pat stopped her bike and turned off the ignition.

"Where do we go now?" she asked, her voice betraying near-total exhaustion.

Pitt spoke without turning. "There," he answered offhandedly, pointing in the general direction of the brick wall. "I suggest you both move your bikes to the side of the tunnel."

Pat and Marquez didn't get it. They still didn't get it after Pitt climbed on the Suzuki, revved up the engine, and spun gravel under the rear wheel as he rode back into the tunnel. After a short minute, he was heard accelerating down the tracks toward them, the Suzuki's headlight beam dancing madly off the timbers.

Marquez reckoned Pitt was doing nearly thirty miles an hour when he thrust out his legs and dug his heels onto the twin ore cart rails less than ten yards from the wall, released his grip on the hand controls, and stood up, allowing the Suzuki to speed on from under him. Slumped backward to compensate for his momentum, he actually remained upright for nearly twenty feet before his feet slipped off the rails and he folded into a ball before tumbling through the tunnel like a soccer ball.

The motorcycle stayed on its wheels, but was just starting to lie on its side when it crashed into the brick wall with a protesting screech of metal and a cloud of dust, before bursting through the old decaying bricks and vanishing into the void beyond.

Pat ran over to Pitt's body, which had skidded to a stop and was sprawled on the ground. She would have sworn he had killed himself, but he looked up at her, blood streaming from a gash on his chin, and grinned like a madman. "Let's see Evel Knievel try that one," he said.

Pat stared down at him in amazement. "I can't believe you didn't break every bone in your body."

"None broken," he muttered in pain, as he slowly rose to his feet. "But I think I bent a few."

"That was the craziest thing I ever saw," mumbled Marquez.

"Maybe, but it worked better than I expected." Pitt, clutching his right shoulder, nodded at the hole in the brick wall. He stood there, getting his breath and waiting for the pain from bruised ribs and a dislocated shoulder to ease, while Marquez began pulling away the bricks loosened by the bike's passage to enlarge the entry.

The miner peered around the fractured wall and aimed his miner's lamp inside. After a few seconds, he looked back and said, "I think we're in deep trouble."

"Why?" asked Pat. "Can't we get out that way?"

"We can get out," said Marquez, "but it's going to cost us big time."

"Cost?"

Pitt limped painfully to the opening and peered inside. "Oh, no," he groaned.

"What is it?" Pat demanded in exasperation.

"The motorcycle," said Pitt. "It crashed into the wine cellar of the hotel restaurant. There must be a hundred broken bottles of vintage wine flowing down a drain in the floor."

Sheriff James Eagan, J R., was directing the rescue operation at the Paradise Mine when he received the call from his dispatcher informing him that Luis Marquez was being held in custody by the Telluride town marshal's deputies at the New Sheridan Hotel for breaking and entering. Eagan was incredulous. How was this possible? Marquezs wife had been adamant in claiming her husband and two others were trapped inside the mine by the avalanche. Against his better judgment, Eagan turned over command of the rescue operation and drove down the mountain to the hotel.

The last thing he expected to find was a mangled motorcycle sitting amid several cases of smashed bottles of wine. His astonishment broadened when he stepped into the hotel's conference room to confront the confessed culprits and found three damp, dirty, and bedraggled people, two men and one woman, one of them wearing a torn and tattered diver's wet suit. All were in handcuffs and in the custody of two deputy marshals, who stood with solemn expressions on their faces. One of them nodded at Pitt.

"This one was carrying an arsenal."

"You have his weapons?" Eagan asked officially.

The deputy nodded and held up three Para-Ordnance .45-caliber automatics.

Satisfied, Eagan turned his attention to Luis Marquez. "How in hell did you get out of the mine and wind up here?" he demanded in complete bewilderment.

"It doesn't matter!" Marquez snapped back. "You and your deputies have got to go down the tunnel. You'll find two dead bodies and a college professor, Dr. Ambrose, who we left guarding a killer."

There was a genuine feeling of skepticism, almost total disbelief, in Sheriff Jim Eagan's mind as he sat down, tipped his chair back on two legs, and pulled a notebook from the breast pocket of his shirt. "Suppose you tell me just what is going on here."
