True Crime, Adaptation or Inspired Fiction? What to Read Next

Psycho is fictional horror associated with a real case; The Good Nurse adapts a reported book; Inventing Anna draws on journalism while a separate memoir offers another perspective. Start with the relationship you want to explore. These distinctions help you choose the right title and avoid treating invented scenes as evidence.
