Bell saw his checkerboard suit disappear in the scrum. He jumped from the rail to the deck and swung down to the main deck, landing on fallen men, kicking to his feet and running after Clay, who was racing toward the stern, straight-arming men out of his way. Suddenly, he cut across the open freight deck.

Bell veered after him.

Clay yanked a gun and fired three shots without breaking stride. Two fanned Bell’s face, the third drilled the brim of his hat, whirling it from his head. Bell stopped running and took careful aim with his Colt Army and triggered it just as Clay turned to fire again. He cried out as Bell’s shot, intended for his head, creased his hand instead when he raised his gun. The gun went flying. But the wound did not slow him as he leaped up the boiler deck stairs, slinging the Merriam Pack off his shoulders and clutching it by the straps.

Bell knew he was heading for the furnaces, intending to bomb a boiler.

He spotted him from the top of the stairs and again took careful aim.

The Colt roared. The shot staggered Clay. His arm dropped straight to his side, and the pack slipped from his hand. But he kept moving, ever swift and indestructible. He scooped up the fallen bag with his other hand and darted toward the nearest furnace. Bell took aim again. Firemen, panicked by gunshots and ricocheting lead, scattered for cover, blocking Bell’s shot. Henry Clay ran past the open furnace and tossed the pack underhand with a softball pitcher’s smooth delivery.

Bell saw a cloud of sparks as it landed in the shimmering bed of cherry red coals. In the half second he took to reach the firebox door, the canvas was burning brightly. He had to pull it out before the fire burned though the canvas and ignited the fuse.

Bell grabbed a fireman’s rake, reached into the blaze, caught the strap, and yanked. The strap burned through, and it broke. He thrust the rake again, caught the wooden frame, which was drenched in flame, and pulled it out. The pack fell, smoldering, at his feet. “Pull the fuse,” he shouted to the nearest coal miner and tore after Henry Clay, who was racing sternward on the freight deck.

Clay ran out of space where the boiler deck overlooked the White Lady’s fifty-foot stern wheel. Bell caught up. The wheel was throwing spray as paddle blade after paddle blade climbed out of the water behind the boat, circled through the air, and plunged down to push again. Henry Clay turned with a smile on his face and a derringer in his unwounded hand and fired. The bullet seared the heel of Bell’s hand. His thumb and fingers convulsed. His gun fell to the deck and bounced into the narrow slot between the back of the boat and the stern wheel.
