Metal screeched. The lever bucked in his hands. Sparks fountained skyward. Bell pushed the brake with every sinew in his body. Swift and purposeful action and determined muscle and bone appeared to slow the runaway. Several more quick-thinking men ran alongside in hopes of leaping on the brakes of the other cars.

But the weight of the coal was too great, the momentum too strong.

Suddenly, with a bang almost as explosive as the parting bridle chain, the iron pin connecting the lever to the brake shoes snapped. The lever swung freely. Bell, shoving it with all his might, lost his balance. The rails and crossties blurred under him as the train accelerated. Only lightning reflexes and a powerful grip on the top rim of the coal car saved him from falling.

The car swayed violently as it gained speed. Being the last car, unanchored by any behind it, the same lateral forces that cracked a whip slammed it sideways against the ventilator house that stood close by the tracks. The impact sheared its pillars, and the building collapsed on the giant fan that drove fresh air into the mine. A shattered roof beam jammed its blades.

“Jump!” miners yelled.

Before Bell could choose a direction in which there was room to land, the train stormed through the mouth and into the narrow confines of the haulageway, where to jump would be to smash flesh and blood against timber, stone, steel, and coal. Bell swung his feet onto the coupler and attempted to brace for what was going to be a very sudden stop when they hit bottom.

The coal train swayed in wider and wider arcs with the ever-increasing speed of its descent. The rear car to which Bell clung slammed against shoring timbers, splintering them, and crumbled pillars of coal the miners had left standing to support the ceiling. The front end, nineteen cars ahead of Bell, bore down on a wooden air door that Sammy the doorboy had shut behind it moments earlier as it ascended.

Sammy was addled by twelve hours of work in near darkness and terrified by the roar of the juggernaut hurtling toward him. But he stood at his post, desperately trying to open the door to let it pass. Like a tycoon brushing a beggar out of his way with a haughty hand, the train flung him against the wall, smashed the air door to flinders, and gained speed.

The swaying coal car isaac bell clung to scraped the sides of the tunnel. The screeching, banging impact severed the wires that powered the electric lights, and the train plummeted downward in total darkness.

Bell pressed himself tight against the cold steel to minimize the distance his body would travel at the moment of impact. It could not be much farther to the coal seam at the bottom. Suddenly, the train jumped the tracks. Metal shrieked as it battered the side of the tunnel and threatened to buck him off like a maddened bronco. Instead, it saved the young detective’s life. Sideswiping the walls had the effect of slowing the train. When it finally struck the seam with a thunderclap, he was banged hard against the back of the car, but not so hard as to break bones.

The silence that followed was as deep as the darkness.

Bell leaped down and ran in the dark, back up the route the runaway had taken him, sliding his boots along the crossties to stay in the middle of the track, where he was least likely to smash into anything. He ran as fast as he could with his hands stretched ahead of his face in hopes of feeling an obstruction in time to stop.

He had seconds to get out before he died in the black and airless chaos of the wrecked gallery. For dangers far deadlier than collision lurked in the dark. Damps—poisonous carbonic acid and explosive methane — were collecting quickly as the demolished ventilator ceased to draw fresh air from the surface and expel lethal vapors. Suffocating blackdamp, thick with carbonic acid, would kill him in ten seconds. Fulminating damp, “inflammable air,” marsh gas exuded by the coal, would blow everyone in the mine to Kingdom Come. Thank God, he thought, most of the day shift was out of the mine and the night shift hadn’t entered yet. Only the doorboys were still at their posts.

All of a sudden, the dark lifted. Daylight so soon? But it wasn’t possible. He could not be that close to the mouth. Then he realized that the light was coming from behind him — orange flickering light — the sparkle of fire as gas and coal at the face of the seam ignited. The sudden light saved him from stumbling over a doorboy crawling along the tracks.

Bell yanked him to his feet.

“Stand up! Chokedamp suffocates you down low. Run!”

He shoved the boy ahead of him, and together they ran from the flames and smoke chasing them up the slope. The smoke would spread white damp, odorless carbon monoxide, which would kill them in minutes if they didn’t burn to death first.

They stopped abruptly. The haulageway was blocked. The train had sheared off the pillars of coal that the miners had left standing to brace the ceiling. Unsupported, the ceiling had fallen into the haulageway. A two-foot opening was held up by a single groaning timber.

“I can fit through, mister. I’ll get help.”

“Hold on,” said Bell. It looked like it would collapse any moment. He crawled into the narrow space, braced the groaning timber with his back, and tried to hold the mountain. “O.K., sonny,” he gasped. “Slip by.”

The boy scrambled through.

Bell gently released the pressure and slithered on his belly. Just as he pulled his feet out, the timber snapped. The ceiling collapsed with a roar as tons of coal and slate filled the space.

“Let’s go.”

But the boy was frozen in place, staring at what had almost killed them.

“Close shave,” Bell said lightly to put him at ease, and when that didn’t work he asked, “Did you see if little Sammy got out?”

“Dead,” said the boy. “The train got him.”

“Come on. Let’s get out of here.”

They ran, climbing the slope, until they were stopped by another fall. This one emitted no light from the other side even though they had to be near the mouth. But, through it, they could hear a faint tapping. Picks digging through the fall. They grabbed rocks and pounded on the fall, alerting those on the other side that they were alive.

The picking sounds doubled, and doubled again. Soon Isaac Bell saw light and heard a cheer. Ten men battered through the fall. The first face Bell saw belonged to Jim Higgins, who had led the rescue.

Cheering men pulled them through the opening and reached for more. The cheers died on their lips.

“That’s all?” asked Higgins.

“Little Sammy was killed,” said Bell. “I didn’t see any others. Give me a pick. I’ll show you the way.”

Before they could start down, an explosion rocked the mine from deep within, and the rescuers knew in their hearts that although they would dig all night for more survivors, and dig all the next day, they would never find a living soul.

They started down. Again they were stopped, not by an explosion but by a gang of club-wielding company police led by a Pinkerton, who shouted, “Jim Higgins!”

“Right here, we’re just heading down.”

“Jim Higgins, you’re under arrest.”

“For what?”

“For murdering all them poor little doorboys who died in the mine.”

“I didn’t—”

“You abandoned your post. You caused the accident by failing to throw the derailer switch that would have stopped the runaway.”

“The foreman ordered me to oil—”

“Tell it to the judge,” said the Pinkerton.

Jim Higgins squared his shoulders. “You boys set me up,” he said. “You found out I am a union organizer. You know that beating me up never worked before, so you waited for a chance to take me out of the fight. You put me on the derailer to keep me away from the workers. And now one of your bought-and-paid judges will sentence me to the penitentiary for a crime you all know damned well I never did.”
