The Redundant Bus

By Ivy Anderson

Four patients die aboard an orbital medical module. The official clinical system records clean, ordinary terminal events.

The independent systems disagree.

Investigator Mara Keir is brought in to examine a cluster of deaths that should have been medically unremarkable. Instead, she finds a ninety-three-second gap between what the primary clinical bus reports and what physically independent sensors recorded. Then she discovers a seventh death certificate for a patient who never existed.

As Mara reconstructs the module's competing records, the case expands from corrupted telemetry to legacy cryptographic trust, manipulated medical support, research-data ownership, and a remote network with ties to an investigation she thought she had left behind.

With corporate observers already inbound, Mara has only hours to preserve the evidence before the institution that controls the official record decides what the truth is allowed to look like.

The Redundant Bus is a compact science-fiction mystery novella about forensic systems engineering, medical technology, institutional pressure, and the danger of trusting a single authoritative channel.
