Serial killer narratives have moved from the lurid pages of pulp fiction to nuanced psychological thrillers, mirroring changes in audience appetite and investigative journalism. Early portrayals leaned on sensationalism, while recent works emphasize character depth and systemic critique.
By mapping these shifts, we can identify patterns—such as the rise of anti‑hero protagonists, the influence of true‑crime podcasts, and the growing insistence on ethical representation—while remaining cautious about over‑generalising from individual titles.
