“The Tulare dispatcher heard his motor sputtering when he saw Bell and Josephine fly over. No one’s spotted him since. The last dispatcher who spotted her said Josephine was flying alone.”

“Where is Bell’s support train?”

“Sidelined north of Tulare – probably where he went down.”

Harry Frost pulled his watch from his vest and confirmed the time. By this hour, the water in his gas should have made Isaac Bell smash.

“Get the auto,” he told Mayhew.

With decent luck, Bell was dead. But, at the very least, the Van Dorn posed no threat to Frost’s plan to shoot Josephine out of the sky and wreck Whiteway’s support train.

To Stotts, Frost said, “Move the pointer.”

Mike Stotts ran onto the Southern Pacific main line, rolled up the canvas arrow pointing north and unrolled it pointing northwest up the short line that angled toward the dry hills that rimmed the valley to the west. Then he threw the switch to divert Josephine’s train in the same direction.

Dave Mayhew drove a brand-new Thomas Flyer onto the short line. Frost and Stotts climbed in, and the three raced northwest.

THE ONLY NOISE ISAAC BELL HEARD was the wind humming in the wing stays as he volplaned his yellow machine in gently descending circles. Beef cattle grazed peacefully under him, and a flock of white pelicans stayed on course, proof that he was passing over the ground as silently as a condor.

A storm from the distant Pacific was surmounting the coastal mountains, and the shadow cast by his machine flickered and faded as the sun was covered and uncovered by cloud fragments racing ahead of the heavy thunderheads. As his shadow crept across the rolling hills in lazy curves, Bell maneuvered carefully so as not to let it fall on the Thomas Flyer racing ahead of a dust trail on the short-line tracks.

There were three men in the Thomas. Bell was too high in the air to identify them, even with his field glasses. But the massive bulk of the figure hunched in the backseat of the open auto, and the canvas arrow that had been shifted away from the main line, coupled with poor Eustace’s attempt to sabotage his engine, told him it had to be Harry Frost.

He had spotted the dust trail ten miles after he followed the canvas arrow at the Snake Dance junction and immediately shut off the noisy Gnome. Josephine was safe on the ground thirty miles back, fuming at the delay despite an official time-out sanctioned by Preston Whiteway to give Bell the opportunity to capture Frost.

Bell turned back toward the junction and restarted the Gnome. When he saw the long yellow line that was the Josephine Special, he swooped down to the train, skimmed the roof of the hangar car, which bristled with rifle-toting detectives, turned around again, and led the train after the Thomas, rising to only five hundred feet above the locomotive.

After ten minutes he thought tha

t they would have caught up, but the tracks were empty and the dust trail gone. A broad dry creek appeared ahead, a dip in the rolling land, as the tracks began veering alongside the foothills of the Coast Range mountains. It was bridged by a long wooden trestle.

The tall detective held his control wheel in one hand and scrutinized the trestle with his field glasses. The maze of timbers would offer excellent cover for men with rifles. And they could have hidden the Thomas in its shadows. But he saw neither the men nor their auto. Suddenly he heard two sharp explosions – louder than the roar of the Gnome. He knew they weren’t gunshots. Nor had they come from the trestle but from directly beneath him, as if from the locomotive.

The big black Atlantic slowed abruptly. Its high drive wheels ground sparks from the rails as the engineer fought to stop his long train as fast as he could. The loud reports, Bell realized, had been caused by torpedoes – detonating caps of fulminate of mercury attached to the rails with lead straps to signal trouble ahead. When a locomotive passed over them, they exploded loudly enough for the engineer and fireman to hear over the roar of the firebox and the thunder of the steam.

Bell saw white smoke spewing from the brake shoes under every car, and the train clashed and banged to a halt halfway across the trestle. Instantly, the locomotive emitted five puffs of steam from its whistle. Five whistles signaled a brakeman to jump from the rear car – Preston Whiteway’s private carriage – and run back along the tracks waving a red flag to warn trains steaming behind it that the special had stopped suddenly for an emergency and was blocking the tracks. By then Bell had overflown the train and the trestle.

He saw the glitter of sunlight on glass.

In the same instant, he spotted the Thomas parked in the shadow of a rail-maintenance shack. The sun flashed again on a telescope sight. He counted two rifles braced on the roof of the shack, spitting red fire.

It was a brilliantly laid trap – the train stopped as a distraction, the rock-steady shooting position, the shock of total surprise. And Bell knew that if he were the young aviatrix whose name was painted on the side of his yellow monoplane, Frost would have killed her in the second hail of fire when she veered away instinctively, thus presenting a bigger target broadside.

Isaac Bell dove straight at the shack, sheered away at the last moment to aim clear of his propeller, and emptied his Remington’s five-shot magazine so fast that the sound of the shots blended together in a roar like a cannon. Circling up and back, he saw that he had hit the gunmen to either side of Frost. He extracted the empty magazine, slipped a full one in its place, and dove again.

Frost did not shoot at him. Bell wondered if he had hit Frost, too, and wounded him too badly to fight. But, no, Frost was running to the Thomas. He cranked the motor, jumped in, and drove onto the tracks. Then, to Bell’s puzzlement, he jumped from the auto and knelt briefly beside the rails.

Frost jumped back on the Thomas and drove toward the hills.

Less than ten seconds had expired since the shooting started. Detectives were still leaping from the hangar car. Bell banked hard to chase after the Thomas. But as the Eagle tipped on its side, Bell’s experience with Harry Frost’s relentless cruelty made him look carefully where Frost had knelt.

He saw smoke, a thin white trail of smoke.

Without hesitation, Isaac Bell rammed his blip switch, shoved his wheel forward, and dropped the Eagle toward the tracks. In the midst of the smoke, traveling along the rail, was a moving stud of red fire. Harry Frost had knelt on the rails and coolly lit a fuse – the fuse he had stolen from the Burbank maintenance shop along with detonators and dynamite.

He had packed the trestle with explosives, Bell realized. The attack he had planned had been twofold: shoot Josephine out of the sky, and blow Preston Whiteway’s train to Kingdom Come – along with every Van Dorn riding on it.
