Hennessy himself was a wisp of an old man, short, bald, and deceptively frail looking. He had a ferret’s alert black eyes, a cold gaze that discouraged lying and extinguished false hope, and the heart, his fleeced rivals swore, of a hungry Gila monster. Hours after the tunnel collapse, he was still in shirtsleeves, dictating a mile a minute to a telegrapher, when the first of his dinner guests was ushered in.

The smooth and polished United States senator Charles Kincaid arrived impeccably dressed in evening clothes. He was tall and strikingly handsome. His hair was slick, his mustache trim. No hint of whatever he was thinking-or if he was thinking at all-escaped from his brown eyes. But his sugary smile was at the ready.

Hennessy greeted the politician with barely veiled contempt.

“In case you haven’t heard, Kincaid, there’s been another accident. And, by God, this one is sabotage.”

“Good Lord! Are you sure?”

“So damned sure, I’ve wired the Van Dorn Detective Agency.”

“Excellent choice, sir! Sabotage will be beyond the local sheriffs, if I may say so, even if you could find one up here in the middle of nowhere. Even a bit much for your railway police.” Thugs in dirty uniforms, Kincaid could have added, but the senator was a servant of the railroad and careful how he spoke to the man who had made him and could as easily break him. “What’s the Van Dorn motto?” he asked ingratiatingly. “‘We never give up, never!’ Sir, as I am qualified, I feel it’s my duty to direct your crews in clearing the tunnel.”

Hennessy’s face wrinkled with disdain. The popinjay had worked overseas building bridges for the Ottoman Empire’s Baghdad Railway until the newspapers started calling him the “Hero Engineer” for supposedly rescuing American Red Cross nurses and missionaries from Turkish capture. Hennessy took the reported heroics with many grains of salt. But Kincaid had somehow parlayed bogus fame into an appointment by a corrupt state legislature to represent “the interests” of the railroads in the “Millionaires’ Club” United States Senate. And no one knew better than Hennessy that Kincaid was growing wealthy on railroad-stock bribes.

“Three men dead in a flash,” he growled. “Fifteen trapped. I don’t need any more engineers. I need an undertaker. And a top-notch detective.”

Hennessy whirled back to the telegrapher. “Has Van Dorn replied?”

“Not yet, sir. We’ve just sent-”

“Joe Van Dorn has agents in every city on the continent. Wire them all!”

Hennessy’s daughter Lillian hurried in from their private quarters. Kincaid’s eyes widened and his smile grew eager. Though on a dusty siding deep in the Cascade Range, she was dressed to turn heads in the finest dining rooms of New York. Her evening gown of white chiffon was cinched at her narrow waist and dipped low in front, revealing decolletage only partially screened by a silk rose. She wore a pearl choker studded with diamonds around her graceful neck, and her hair high in a golden cloud, with curls draping her high brow. Bright earrings of Peruzzi triple-cut brilliant diamonds drew attention to her face. Plumage, thought Kincaid cynically, showing what she had to offer, which was plenty.

Lillian Hennessy was stunningly beautiful, very young, and very, very wealthy. A match for a king. Or a senator who had his eye on the White House. The trouble was the fierce light in her astonishingly pale blue eyes that announced she was a handful not easily tamed. And now her father, who had never been able to bridle her, had appointed her his confidential secretary, which made her even more independent.

“Father,” she said, “I just spoke with the chief engineer by telegraphone. He believes they can enter the pioneer tunnel from the far side and cut their way through to the main shaft. The rescue parties are digging. Your wires are sent. It is time you dressed for dinner.”

“I’m not eating dinner while men are trapped.” “Starving yourself won’t help them.” She turned to Kincaid. “Hello, Charles,” she said coolly. “Mrs. Comden’s waiting for us in the parlor. We’ll have a cocktail while my father gets dressed.”

Hennessy had not yet appeared when they had finished their glasses. Mrs. Comden, a voluptuous, dark-haired woman of forty wearing a fitted green silk dress and diamonds cut in the old European style, said, “I’ll get him.” She went to Hennessy’s office. Ignoring the telegrapher, who, like all telegraphers, was sworn never to reveal messages he sent or received, she laid a soft hand on Hennessy’s bony shoulder and said, “Everyone is hungry.” Her lips parted in a compelling smile. “Let’s take them in to supper. Mr. Van Dorn will report soon enough.”

As she spoke, the locomotive whistle blew twice, the double Ahead signal, and the train slid smoothly into motion.

“Where are we going?” she asked, not surprised they were on the move again.

“Sacramento, Seattle, and Spokane.”

FOUR DAYS AFTER THE TUNNEL EXPLOSION, JOSEPH VAN DORN caught up with the fast-moving, far-roaming Osgood Hennessy in the Great Northern rail yard at Hennessyville. The brand-new city on the outskirts of Spokane, Washington, near the Idaho border, reeked of fresh lumber, creosote, and burning coal. But it was already called the “Minneapolis of the Northwest.” Van Dorn knew that Hennessy had built here as part of his plan to double the Southern Pacific’s trackage by absorbing the northern cross-continent routes.

The founder of the illustrious Van Dorn Detective Agency was a large, balding, well-dressed man in his forties who looked more like a prosperous business traveler than the scourge of the underworld. He appeared convivial, with a strong Roman nose, a ready smile slightly tempered by a hint of Irish melancholy in his eyes, and splendid red burnsides that descended to an even more splendid red beard. As he approached Hennessy’s special, the sound of ragtime music playing on a gramophone elicited a nod of heartfelt relief. He recognized the lively, yearning melody of Scott Joplin’s brand-new “Search-Light Rag,” and the music told him that Hennessy’s daughter Lillian was nearby. The cantankerous president of the Southern Pacific Railroad was a mite easier to handle when she was around.

He paused on the platform, sensing a rush from within the car. Here came Hennessy, thrusting the mayor of Spokane out the door. “Get off my train! Hennessyville will never be annexed into your incorporated city. I will not have my rail yard on Spokane’s tax rolls!”

To Van Dorn, he snapped, “Took your time getting here.”

Van Dorn returned Hennessy’s brusqueness with a warm smile. His strong white teeth blazed in his nest of red whiskers as he enveloped the small man’s hand in his, booming affably, “I was in Chicago, and you were all over the map. You’re looking well, Osgood, if a little splenetic. How is the beauteous Lillian?” he asked, as Hennessy ushered him aboard.

“Still more trouble than a carload of Eye-talians.”

“Here she is, now! My, my, how you’ve grown, young lady, I haven’t seen you since-”

“Since New York, when father hired you to return me to Miss Porter’s School?”

“No,” Van Dorn corrected. “I believe the last time was when we bailed you out of jail in Boston following a suffragette parade that got out of hand.”

“Lillian!” said Hennessy. “I want notes of this meeting typed up and attached to a contract to hire the Van Dorn Agency.”

The mischievous light in her pale blue eyes was extinguished by a steady gaze that was suddenly all business. “The contract is ready to be signed, Father.”

“Joe, I assume you know about these attacks.”

“I understand,” Van Dorn said noncommittally, “that horrific accidents bedevil the Southern Pacific’s construction of an express line through the Cascades. You’ve had workmen killed, as well as several innocent rail passengers. ”
