Chapter 10 - The Vent Runner
In the suffocating gloom of the utility closet, the air tasted of sulfur and rust. Lucas worked by touch and the intermittent strobe of lightning, his hands steady despite the adrenaline coursing through his veins.
He stripped the nylon strap from Clara’s heavy-duty medical bag, fashioning a lightweight, secure harness around Pip’s tiny chest. On the end of the strap, he secured a carabiner attached to a length of braided utility paracord that Thomas had untangled from the emergency supply kit.
""Listen to me, Pip,"" Lucas whispered, bringing the small dog’s face level with his own. The puppy’s hazel eyes were wide, taking in Lucas’s every breath. Pip licked Lucas’s nose once, a calm, deliberate gesture of trust that shattered the panic in the small room. ""You go through that pipe. You find the open air. Find Sarah's porch, buddy. Go.""
Clara pried open the rusted iron grating behind the empty water heater. A draft of cold, wet rain air rushed in, carrying the scent of mud and pine, but also revealing the narrow, jagged sheet-metal duct leading through the thick foundation wall.
Thomas knelt beside the vent, his weathered face inches from the opening. He pulled a small, silver dog training whistle from his shirt—an old, familiar object worn smooth by years of use. He blew into it softly; it emitted a faint, high-frequency hiss that humans could barely detect.
Pip’s ears shot forward.
""Pip, seek!"" Thomas commanded, his voice breaking with emotion. ""Seek the whistle, boy!""
Without a second of hesitation, the fawn Chihuahua lunged forward into the dark pipe.
Lucas fed the paracord through his palms, inch by inch, his breath held tight. Ten feet. Twelve feet. Fifteen feet. The metal conduit groaned as the puppy scrambled through years of dust and spiderwebs.
Suddenly, the cord stopped moving.
The hissing of the propane valve outside grew louder. Behind them, one of the dogs in the hallway let out a choked, desperate whimper as the gas level reached knee height.

""He stopped,"" Clara whispered in horror. ""Lucas, the cord is slack.""
Lucas tugged gently on the line. It didn't budge. It was caught on something inside the dark metal shaft. Through the wall, there was no sound—only the drumming rain and the deadly, invisible gas creeping closer to their lungs.
