turned, stepped over the limp body of her partner, and entered the baggage car, closing the door behind him.
Kane led him to the porterâs body. The man had been shoved under a set of steel bulkhead shelves. Judging from the bruising, he had been strangled to death.
âIâm sorry,â Tucker murmured.
He donned his jacket, gloves, and cap, then slung his rucksack over his shoulder. At the rear of the car, he used the porterâs keys to unlock the metal door. It swung open, and a rush of wind shoved him sideways. The rattling of the trainâs wheels filled his ears.
Directly ahead was the caboose door.
With Kane following closely, Tucker stepped onto the open platform, shut the door behind him, then unlocked the caboose and stepped into the last car. He hurried across to the rear, through the last doorâÂand a moment later, they were at the tail end of the Trans-ÂSiberian Express, standing on a railed catwalk.
Beneath them, tracks flashed past. The sky was clear and black and studded with stars. To their right, a slope led to a partially frozen river; to their left, scattered snowdrifts. The locomotive was chugging up a slight grade, moving well below its average speed, but still much faster than Tucker would have liked.
He tugged the collar of his jacket up around his neck against the frigid night.
At his knee, Kane wagged his tail, excited. No surprise there. The shepherd was ready to go, come what may. Tucker knelt and cupped Kaneâs head in both of his hands, bringing his face down close.
âWhoâs a good boy?â
Kane leaned forward, until their noses touched.
âThatâs right. You are.â
It was a routine of theirs.
Standing but keeping a grip on Kaneâs vest collar, Tucker navigated the catwalk steps until they were only a few feet above the racing ground. He poked his head past the cabooseâs side, looking forward, waiting, watching, until he saw a particularly thick snowdrift approaching.
âReady, boy?â he said. âWeâre gonna jump! Steady now . . . steady . . .â
The snowdrift flashed into view. Tucker tossed his rucksack out into the darkness.
âG O , K ANE ! J UMP !â
Without hesitation, the shepherd leaped out into the night.
Tucker waited a beat, then followed.

March 8, 11:24 P.M.
Siberia, Russia
Tucker immediately realized all snowdrifts were not alike, especially in Siberia. Having gone through weeks of thawing and freezing, the driftâs face had become armored by several inches of ice.
He hit the frozen surface hip-Âfirst, hoping to transition into a roll.
It was not to be.
He crashed through the top of the berm before his momentum flipped his legs up and over his head, sending him into a somersault down the driftâs rear slope. He slammed onto his back and began sliding on his butt down the long, steep surface, his heels stuttering over the ice-Âencrusted snow. He tried jamming his elbows into the drift, to slow himself, but got no traction. To his right, alarmingly close, rose a lizard-Âback of boulders.
Above him, he heard a growl. He tipped his head back in time to see Kaneâs sleek form come galloping down the slope. The shepherd was there in seconds and clamped his teeth into Tuckerâs jacket collar. Once latched on, Kane sat down on his haunches and lifted his head, his strong back muscles straining to take Tuckerâs weight.
Ahead and a few feet to the right, a sapling jutted from the snow. On impulse, he swung his left leg out, curled it, and hooked the trunk with his ankle. The momentum whipped him around, dragging Kane along, too, before jerking them both to a sudden stop.
All was quiet.
Tucker lay perfectly still and mentally scanned his body. Nothing seemed broken. He could feel Kaneâs weight hanging from his collar.
âKane? Howâre you doing, pal?â
The shepherd replied with a muffled growl that Tucker recognized as
