The Chilean podcast ¿Quién mató a Anna Cook? (Who killed Anna Cook?) tells the story of Anna Cook — a DJ found dead in her home in Santiago in August of 2017 — and those suspected of murdering her. Her death had a significant impact on Chilean society, and her name became a slogan during a series of massive protests that swept the country beginning in 2019. Within a month of the podcast’s release, it reached more than 350,000 reproductions. In this review, audio producers and journalists Tomás Uprimny and Charlotte de Beauvoir analyse the podcast in conversation and reflect on its storytelling, sound design and unusual use of fictional hosts.
