“They can’t all be accidents.” Hennessy retorted sternly. “Someone’s doing his damnedest to wreck this railroad. I’m hiring your outfit to hunt down the saboteurs, whether anarchists, foreigners, or strikers. Shoot ‘em, hang ’em, do what you have to do, but stop them dead.”

“The instant you telegraphed, I assigned my best operative to the case. If the situation appears as you suspect, I will appoint him chief investigator.”

“No!” said Hennessy. “I want you in charge, Joe. Personally in charge.”

“Isaac Bell is my best man. I only wish I had possessed his talents when I was his age.”

Hennessy cut him off. “Get this straight, Joe. My train is parked only three hundred eighty miles north of the sabotaged tunnel, but it took over seven hundred miles to steam here, backtracking, climbing switchbacks. The cutoff line will reduce the run by a full day. The success of the cutoff and the future of this entire railroad is too important to farm out to a hired hand.”

Van Dorn knew that Hennessy was used to getting his way. He had, after all, forged continuous transcontinental lines from Atlantic to Pacific by steamrollering his competitors, Commodore Vanderbilt and J. P. Morgan, outfoxing the Interstate Commerce Commission and the United States Congress, and staring down trust-busting President Teddy Roosevelt. Therefore, Van Dorn was glad for a sudden interruption by Hennessy’s conductor. The train boss stood in the doorway in his impeccable uniform of deep blue cloth, which was studded with gleaming brass buttons and edged with the Southern Pacific’s red piping.

“Sorry to disturb you, sir. They’ve caught a hobo trying to board your train.”

“What are you bothering me for? I’m running a railroad here. Turn him over to the sheriff.”

“He claims that Mr. Van Dorn will vouch for him.”

A tall man entered Hennessy’s private car, guarded by two heavyset railway police. He wore the rough garb of a hobo who rode the freight trains looking for work. His denim coat and trousers were caked with dust. His boots were scuffed. His hat, a battered cow-poke’s J. B. Stetson, had shed a lot of rain.

Lillian Hennessy noticed his eyes first, a violet shade of blue, which raked the parlor with a sharp, searching glance that penetrated every nook and cranny. Swift as his eyes were, they seemed to pause on each face as if to pierce the inner thoughts of her father, Van Dorn, and lastly herself. She stared back boldly, but she found the effect mesmerizing.

He was well over six feet tall and lean as an Arabian thorough-bred. A full mustache covered his upper lip, as golden as his thick hair and the stubble on his unshaven cheeks. His hands hung easily at his sides, his fingers were long and graceful. Lillian took in the determined set to the chin and lips and decided that he was about thirty years old and immensely confident.

His escort stood close by but did not touch him. Only when she had torn her gaze from the tall man’s face did she realize that one of the railroad guards was pressing a bloody handkerchief to his nose. The other blinked a swollen, blackened eye.

Joseph Van Dorn allowed himself a smug smile. “Osgood, may I present Isaac Bell, who will be conducting this investigation on my behalf?”

“Good morning,” said Isaac Bell. He stepped forward to offer his hand. The guards started to follow after him.

Hennessy dismissed them with a curt “Out!”

The guard dabbing his nose with his handkerchief whispered to the conductor who was herding them toward the door.

“Excuse me, sir,” said the conductor. “They want their property back.”

Isaac Bell tugged a leather-sheathed sap of lead shot from his pocket. “What’s your name?”

“Billy,” came the sullen reply. Bell tossed him the sap, and said coldly, with barely contained anger, “Billy, next time a man offers to come quietly, take him at his word.”

He turned to the man with the black eye. “And you?”

“Ed.”

Bell produced a revolver and passed it to Ed, butt first. Then he dropped five cartridges into the guard’s hand, saying, “Never draw a weapon you haven’t mastered.”

“Thought I had,” muttered Ed, and something about his hang-dog expression seemed to touch the tall detective.

“Cowboy before you joined the railroad?” Bell asked.

“Yes, sir, needed the work.”

Bell’s eyes warmed to a softer blue, and his lips spread in a congenial smile. He slid a gold coin from a pocket concealed inside his belt. “Here you go, Ed. Get a piece of beefsteak for that eye, and buy yourselves a drink.”

The guards nodded their heads. “Thank you, Mr. Bell.”

Bell turned his attention to the president of the Southern Pacific Company, who was glowering expectantly. “Mr. Hennessy, I will report as soon as I’ve had a bath and changed my clothes.”

“The porter has your bag,” Joseph Van Dorn said, smiling.

THE DETECTIVE WAS BACK in thirty minutes, mustache trimmed, hobo garb exchanged for a silver-gray three-piece sack suit tailored from fine, densely woven English wool appropriate to the autumn chill. A pale blue shirt and a dark violet four-in-hand necktie enriched the color of his eyes.

Isaac Bell knew that he had to start the case off on the right foot by establishing that he, not the imperious railroad president, would boss the investigation. First, he returned Lillian Hennessy’s warm smile. Then he bowed politely to a sensual, dark-eyed woman who entered quietly and sat in a leather armchair. At last, he turned to Osgood Hennessy.

“I am not entirely convinced the accidents are sabotage.”

“The hell you say! Labor is striking all over the West. Now we’ve got a Wall Street panic egging on radicals, inflaming agitators.”

“It is true,” Bell answered, “that the San Francisco streetcar strike and the Western Union telegraphers’ strike embittered labor unionists. And even if the leaders of the Western Federation of Miners standing trial in Boise did conspire to murder Governor Steunenberg-a charge I doubt, as the detective work in that case is slipshod-there was obviously no shortage of vicious radicals to plant the dynamite in the Governor’s front gate. Nor was the murderer who assassinated President McKinley the only anarchist in the land. But-”

Isaac Bell paused to turn the full force of his gaze on Hennessy. “Mr. Van Dorn pays me to capture assassins and bank robbers everywhere on the continent. I ride more limited trains, expresses, and crack flyers in a month than most men will in a lifetime.”

“What do your travels have to do with these attacks against my railroad?”

“Train wrecks are common. Last year, the Southern Pacific paid out two million dollars for injuries to persons. Before 1907 is over, there’ll be ten thousand collisions, eight thousand derailments, and over five thousand accidental deaths. As a frequent passenger, I take it personally when railroad cars are rammed inside each other like a telescope.”

Osgood Hennessy flushed pink with incipient fury. “I’ll tell you what I tell every reformer who thinks the railroad is the root of all evil. The Southern Pacific Railroad employs one hundred thousand men. We work like nailers transporting one hundred million passengers and three hundred million tons of freight every year!”

“I happen to love trains,” Bell said, mildly. “But railwaymen don’t exaggerate when they say that the tiny steel flange that holds the wheel on the track is ‘One inch between here and eternity.”’

Hennessy pounded the table. “These murdering radicals are blinded by hate! Can’t they see that railway speed is God’s gift to every man and woman alive? America is huge! Bigger than squabbling Europe. Wider than divided China. Railroads unite us. How would people get around without our trains? Stagecoaches? Who would carry their crops to market? Oxen? Mules? A single one of my locomotives hauls more freight than all the Conestoga wagons that ever crossed the Great Plains-Mr. Bell, do you know what a Thomas Flyer is?”
