Havoc was a Multi-Purpose Canine, an MPC. Rigorously trained in explosive detection, fugitive tracking, and controlled, lethal aggression, Havoc had jumped out of military cargo planes from thirty thousand feet strapped tightly to Jackson’s chest. The dog had saved Jackson’s life more times than the SEAL could accurately count. Havoc was explicitly conditioned to be entirely indifferent to civilians. He was trained to completely ignore other dogs, deafening loud noises, food dropped right in front of him on the floor, and the sound of people crying. Havoc only ever reacted to active threats, direct commands from Jackson, and the distinct chemical scent of hidden explosives or extreme human adrenaline.
Which was precisely why what happened next made the blood in Jackson’s veins run cold.
The train was rapidly picking up speed, rattling heavily as it climbed out of the dark subterranean tunnels beneath New York City and burst out into the fading, golden-orange light of the late afternoon. I shifted uncomfortably in my seat, trying to find an angle that didn’t pinch my sciatic nerve.
Without warning, a sharp, entirely involuntary muscle spasm violently racked my right leg. The sudden jerk caused my heavy titanium brace to clank loudly against the solid metal frame of the seat directly in front of me. I gasped sharply, biting down on my lower lip hard enough to taste the hot, metallic tang of my own blood, desperately trying to suppress any further physical reaction. I hated drawing attention to myself. I hated looking weak and broken in public.
Down on the floor, Havoc’s ears instantly swiveled like highly tuned radar dishes. Jackson watched the dog carefully from the corner of his eye. He fully expected Havoc to maintain his strict down-stay position. It was a foundational command deeply ingrained into the dog’s very DNA. Unless Jackson explicitly released him, Havoc was supposed to remain practically invisible.
But Havoc broke command.
Slowly, and with total silence, the massive German Shepherd rose to his feet. Jackson instantly stiffened, his right hand instinctually dropping beneath his jacket toward the concealed custom Sig Sauer P365 pistol he carried securely inside his waistband. In six years of combat deployments, Havoc only ever broke command if he detected an imminent, lethal threat—a hidden bomb, an impending ambush, or a concealed weapon being quickly drawn.
But Havoc did not look aggressively down the train aisle. He did not sniff the recycled cabin air for the sharp scent of cordite or C4 explosives. Instead, the massive dog turned his entire body specifically toward me.
I froze completely as the ninety-pound apex predator suddenly loomed directly over my lap. The dog’s head was massive, framed by thick fur, its powerful jaws fully capable of crushing solid bone with hundreds of pounds of pressure per square inch. I held my breath, absolutely terrified to move an inch, terrified that any sudden flinch might trigger the animal’s prey drive.
Jackson opened his mouth to issue a sharp, immediate correction command—”Platz”—but the stern word died in his throat.
Havoc didn’t bare his pristine white teeth. He didn’t emit even the faintest rumble of a growl. Instead, the formidable dog did something Jackson had never seen him do in his entire life. Havoc deliberately, and incredibly gently, lowered his massive head and rested his heavy chin squarely onto my trembling, metal-braced leg.
I let out a small, highly shocked gasp. Havoc responded by letting out a long, low, rumbling sigh, his bright amber eyes looking up at my face with a look of intense, unmistakable focus. Then, the dog shifted his entire body weight. He wedged himself tightly into the small, confined space between my legs and the open aisle. He sat up incredibly tall, his broad chest proudly puffed out, his muscular back rigid. He had intentionally positioned himself as a literal, physical barrier between my fragile, broken body and the rest of the crowded train carriage.
He’s guarding her, Jackson realized, his tactical mind racing to catch up with his dog’s instincts.
“I… I’m sorry,” I whispered, my shaking hands hovering nervously in the air just over the dog’s head, completely unsure if I was even legally allowed to touch a working military animal. “Is he… is he okay?”
Jackson slowly turned his head to look at me fully for the first time. He quietly studied the deep, bruised lines of absolute exhaustion etched around my eyes, the sickly pallor of my skin, and the faint, uncontrollable trembling in my pale hands. He then looked down at Havoc, who was now staring fixedly down the length of the aisle, his ears pinned back slightly in a clear, defensive posture.
“He’s fine,” Jackson said. His voice was a deep, gravelly baritone, a voice clearly roughened by years of breathing in arid desert dust and shouting over the deafening roar of helicopter rotor wash. “He just… he doesn’t usually do this.”
“Do what?” I asked softly. I finally gathered the courage to let my shaking fingers brush against the thick, remarkably coarse fur right behind Havoc’s ears. To Jackson’s absolute, silent astonishment, Havoc actually leaned into my touch, seeking the comfort, yet never once breaking his hyper-vigilant stare down the center aisle.
“He’s an MPC. A military working dog,” Jackson explained quietly, deliberately keeping his low voice from carrying over the rhythmic hum of the speeding train. “He’s heavily trained to find bombs and bad guys. He’s not a service dog meant for… comfort. He doesn’t interact with regular people.”
I looked down in wonder at the massive, lethal animal currently using my painful, braced leg as a comfortable chin rest. “Then why is he doing this?”
Jackson frowned, a deep crease forming between his brows. His sharp eyes immediately began scanning the carriage. His extensive SEAL training, honed over a decade and a half of surviving in the deadliest, most unforgiving environments on Earth, kicked into high overdrive. Havoc wasn’t just being affectionate. Elite dogs like Havoc possessed an olfactory system capable of smelling minute chemical changes in the human body. They could literally smell human fear, sudden spikes in adrenaline, and malicious, violent intent.
Havoc had undoubtedly recognized that I was physically vulnerable, yes. But it was far more than that. Havoc had specifically positioned his body defensively against the open aisle. He was actively shielding me from something.
Or someone.
Jackson’s cold, calculating gray eyes methodically swept over the passengers sitting in the rows immediately ahead of us.
Row twelve. An elderly couple. Both completely asleep, heads resting against the glass.
Row thirteen. A scruffy college kid wearing oversized headphones, aggressively typing away on a glowing laptop.
Row fourteen. An exhausted mother desperately trying to keep her squirming toddler quiet with an iPad playing cartoons.
Row fifteen. A man dressed in a meticulously tailored, expensive-looking navy blue suit.
Jackson’s piercing gaze locked squarely onto the man in the blue suit.
