The Guardian is inviting readers to name their favourite true crime television documentary and explain why it stands out. The request follows the publication’s compilation of notable programmes in the genre, including OJ: Made in America and Tiger King, and may inform a future feature.

People aged 18 or over can submit responses through an encrypted form, with the option to remain anonymous. Contributors can choose whether their comments may be published, provide optional contact details, and indicate whether they would be willing to speak to the Guardian’s audio or video teams; personal data will be deleted when no longer needed for the feature.
