A whisper from the past... a secret buried for six decades... and a disease that was never meant to be seen.When Dr. Arvind Sen, medical investigator and reluctant truth-seeker, receives the last desperate warning of a murdered colleague, he is pulled into a maze of hidden laboratories, silenced experiments, and outbreaks that defy nature. What he uncovers is more terrifying than any virus: a decades-long project known only as Heliotrope, where human lives were turned into living experiments.Now, as mysterious seizures erupt in hospitals across continents and aid shipments conceal death instead of relief, Arvind and a small band of allies must fight not just a pathogen but a system designed to weaponize silence itself. Every step closer to the truth brings them face-to-face with shadow operatives, global conspirators, and one chilling reality: the survival of humanity may hinge on Last Patient Zero.Fast-paced, chilling, and disturbingly plausible, Last Patient Zero is an unflinching thriller that asks: What if the greatest epidemic of our time was engineered, and what if the only antidote was the truth?
