📝 Description: Dead Letter Protocol

Alden Mercer’s Dead Letter Protocol presents a claustrophobic tale of industrial horror. Leland Fisk works the night shift at a Mail Recovery Center, a vast facility dedicated to processing forgotten correspondence. His solitary routine fractures when he discovers his own house keys inside an unmarked cardboard box. The situation deteriorates rapidly as his phone rings from within a moving package on the conveyor belt. The narrative follows Leland’s desperate struggle against automated systems that turn hostile. A rogue manager manipulates the machinery to block emergency exits and tag Leland as contraband. He becomes the target of hunting sorting equipment in a maze of industrial gear. Mercer, known for his work with Antillas Publishing House, crafts a story where technology acts with malicious intent. The plot focuses on survival within a constricting environment of heavy crates and conveyor belts. This book suits readers who enjoy psychological thrillers grounded in mundane settings turned sinister. It appeals to fans of corporate horror and technological dread. Those seeking supernatural ghosts or historical gothic romance may find the strictly mechanical antagonism lacking. The story remains tightly focused on the physical threat posed by the facility's infrastructure and its unseen controller.
