"Badge of Infamy" by Lester Del Rey is a science fiction novel written in the mid-20th century. The story unfolds in a dystopian future where societal structures, governed by powerful medical and space lobbies, have left the protagonist, Dr. Daniel Feldman, as a pariah condemned for his actions. The narrative follows Feldman's struggle for survival, grappling with his past as a medical professional while contending with a deadly plague that threatens the Martian colonies. At the start of the novel, Feldman is introduced in a bleak and squalid flophouse, reflecting on his fall from grace after a tragic incident that led to him being ostracized. His situation worsens as he encounters a sick fellow lodger, highlighting both his helplessness and his medical training. Feldman's internal conflict is palpable as he battles his instincts to help the dying man against the fear of punishment from the Medical Lobby, which enforces strict regulations on medical practice. The opening sets the stage for Feldman's subsequent journey, moving through themes of ethical responsibility, societal control, and the fight against an emerging Martian disease, shaping a narrative that promises both tension and introspection as he navigates his complex world.
