Bell strode down the boarding stage and hurried across the point to the powder shed the miners had erected far from the tents to store the fresh dynamite they’d managed to smuggle in at night. They were guarding it closely, recalling, no doubt, the accidental explosion that nearly sank the Sadie and half her barges. The Powder Committee remembered, too, the tall detective, who had recommended—at gunpoint—that the dynamite ride in its own barge apart from the people, and greeted him warmly.

“That’s a handsome steamboat you brought us, Mr. Bell. What can we do for you?”

“I need,” said Bell, “one stick of dynamite, a blasting cap, and a short safety fuse.”

“Want me to assemble it?”

“Appreciate it.”

He watched as the miner worked quickly but meticulously.

“How short a fuse do you want?”

“Give me ten seconds.”

The miner looked at him. “I hope you can run fast.”

“Fast enough.” Bell slipped the greasy red stick in his coat and gestured with his cigar. “Got a light?”

“Let’s move away from the powder shed.” The miner struck a match and shielded the flame from the wind and rain until Bell got the cigar lit and glowing.

“Thank you.”

“I’d recommend keeping the business end away from that fuse.”

Puffing on the cigar, trailing aromatic smoke, Isaac Bell walked up the slope to the gun emplacement. The Hotchkiss was oiled and well cared for, not a speck of rust on the wheels or the tube, and the men serving looked like they knew their business. They had seen White Lady arrive and echoed the gratitude of the men at the powder shed.

Bell turned around as if to admire the steamer, which gleamed in the Pittsburgh murk as tall and long and white as the finest seaside resort. He puffed the red-hot coal at the front of his cigar, took the dynamite from his pocket, touched the cigar to the fuse, and puffed up a cloud of smoke to distract the gun crew as he faced the cannon and slid the cylinder of dynamite down the four-foot barrel.

“What did you—”

Hurrying down the hill at a fast lope, Bell called over his shoulder in a commanding voice, “Run for it! It’s dynamite. Archie!”

Fifty yards down, he looked back. The dynamite went off with a muffled peal. The gun jumped off its wheels, and the breech peeled open as if made of paper. The crew gathered around the shattered weapon. Angry men ran after Bell, shouting:

“What did you do to us?”

Bell kept walking fast, signaling Archie not to pull the shotgun until they really needed it.

“Why?”

“What did you do to us?”

“I’m hoping I saved your damned fool lives,” Bell said.

“How can we beat ’em? How can we win?”

The shouts died on their lips. All eyes flew to the top of the tipple. A lookout was bellowing through cupped hands:
