Mowery fumbled for a pencil and drew a sketch of the pier standing in the water. At the foot of the pier, he scratched the pencil point through the paper.
“We call it scour. The effect of scour occurs when the water scoops a hole in the riverbed immediately upstream of the pier. All of a sudden, the footing is not supported. It will plunge into this hole or crack under the unequal forces… We have built our house on sand.”

ISAAC BELL WALKED ACROSS THE CASCADE CANYON BRIDGE.
The span was dead silent. All train traffic had been stopped. The only sounds Bell could hear were the click of his boot heels and the echo of the rapids far below. No one knew how unstable the bridge was yet, but the engineers all agreed it was only a matter of time and water flow before it fell. When he reached the midpoint between the lips of the gorge, he stared down at the river tumbling against the flawed piers.
He was staggered by the Wrecker’s audacity.
Bell had wracked his brain to predict how the Wrecker would attack the bridge. He had guarded every approach, guarded the piers themselves, and watched the work gangs with an eagle eye. It had never occurred to him that the criminal had already attacked it, two full years ago, before they started building the bridge.
Bell had stopped him in New York City. He had stopped him on the rails. He had stopped him all the way through Tunnel 13 right up to the bridge. But here, under this bridge, the Wrecker had proved his mettle with a devastating long-term counterthrust in case all else failed.
Bell shook his head partly in anger and partly in grim admiration for his enemy’s skills. The Wrecker was despicable, a merciless killer, but he was formidable. This sort of planning and execution went far beyond even the New York dynamite attack.
All that Isaac Bell could say in his own defense was that when the Cascade Canyon Bridge fell into the gorge, at least it would not come as a surprise. He had uncovered the plot before the catastrophe. No train loaded with innocent workmen would fall with it. But though no people would die, it was still a catastrophe. The cutoff, the vast project he had vowed to protect, was as good as dead.
He sensed someone walking toward him and knew who it was even before he smelled her perfume.
“My darling,” he called without turning his bleak gaze from the water, “I’m up against a mastermind.”
“A ‘Napoleon of crime’?” Marion Morgan asked.
“That’s what Archie calls him. And he’s right.”
“Napoleon had to pay his soldiers.”
“I know,” Bell said bleakly. “Think like a banker. That hasn’t gotten me very far.”
“There is something else to remember,” said Marion. “Napoleon may have been a mastermind, but in the end he lost.”
Bell turned around to look at her. Half expecting a sympathetic smile, he saw instead a big grin filled with hope and belief. She was incredibly beautiful, her eyes alight, her hair shining as if she had bathed in sunlight. He could not help but smile back at her. Suddenly, his smile exploded into a grin as broad at hers.
“What is it?” she asked.
“Thank you for reminding me that Napoleon lost.”
She had set his mind churning again. He scooped her exuberantly into his arms, winced from the lingering pain of Philip Dow’s bullet to his right arm, and shifted her smoothly into his unscathed left.
“Once again I have to leave you right after you arrive. But this time it’s your fault because you really made me think.”
“Where are you going?”
“I’m going back to New York to interrogate every banker in the railroad business. If there’s an answer to the riddle of why he is attacking this railroad, it will come from Wall Street.”
“Isaac?” Marion took his hand, “Why don’t you go to Boston?”
“The biggest banks are in New York. Hennessy and Joe Van Dorn can pull strings. I’ll start with J. P. Morgan and work my way down.”
“The American States Bank is in Boston.”
“No.”
“Isaac, why not ask your father? He is vastly experienced in finance. When I worked in banking, he was a legend.”
Bell shook his head. “I’ve told you that my father was not happy that I became a detective. In truth, he was heartbroken. Men who are legends hope their sons will continue building on the foundations that they laid. I do not regret going my own way. But I have no right to ask him to forgive me.”
