Oliver Thaddeus is a man built on precision. A high-end private investigator who fled a shattered life in San Diego, he moved to Denver seeking the “Cost of Clean”—a sterile, ordered existence where the ghosts of betrayal couldn’t reach him. But when he discovers his reclusive, enigmatic neighbor, Noah Blain, standing in a foyer transformed into a literal butcher shop, Oliver’s carefully constructed walls begin to crumble.

Noah is a survivor of a different kind—a man haunted by a childhood of fire and a family legacy of greed. When his estranged relatives are found slaughtered in his home, Noah becomes the primary suspect in a game of theatrical violence. As the “Butcher” begins leaving gruesome “welcome gifts” across the city, Oliver realizes that protecting Noah isn’t just a job; it’s a mission to save the only man who has ever truly seen him.

Together, they must navigate the shadows of the Alcott Archive, a web of hidden apartments and centuries-old secrets buried beneath the limestone of Denver’s elite. With a team of high-tech outcasts and the weight of a 5280-foot elevation pressing down on them, Oliver and Noah race to unmask a killer who turns human lives into inventory.

In a city where the air is thin and the secrets are deep, Oliver must decide: how much is he willing to pay to keep the past from claiming his future?
