13 Days of Halloween

13 Days of Halloween is an audio horror event that drops daily episodes from October 19th through Halloween night, building a single terrifying narrative across 13 installments. Produced by iHeartPodcasts and Grim & Mild (the production company behind Lore), each season tells a completely new story with professional voice actors, cinematic sound design, and writing that feels more like a prestige horror film than a podcast. The show has run four seasons so far, with the most recent airing in 2023. Season One followed a trick-or-treater visiting increasingly disturbing houses on a single Halloween night. Later seasons have featured Keegan-Michael Key and Natalie Morales in starring roles, bringing serious acting talent to what could have been a novelty concept. Season Four placed its protagonist in the mysterious Pendleton Rehabilitation Center, blurring the line between psychological thriller and supernatural horror. With 57 episodes across all seasons and a 4.6 rating from nearly 2,500 reviews, the show punches well above its weight for a seasonal release. The daily format creates a genuine countdown-to-Halloween energy that works perfectly for October listening. Each episode runs 15 to 30 minutes, short enough to consume in a single commute but dense enough to leave you thinking about it afterward. The production quality is what sets this apart from the hundreds of Halloween fiction podcasts out there. Grim & Mild knows how to create atmosphere through audio, and the team clearly invests significant resources into making each season feel like a complete, polished horror experience. Fans have been vocal about wanting a Season Five, so this one may not be finished yet.
