Hi, Grim & Mild superfans! We're excited for the season 4 return of 13 Days of Halloween. Subtitled "Penance," this brand-new story unfolds over the span of 13 days and is sure to keep you on the edge of your seat. "Penance" stars Natalie Morales (Parks and Recreation, Dead to Me), and we think you'll want to join in on the spooky fun. Check out this trailer to get excited and start listening on 10/19 until the story concludes on Halloween day. Season Description: Season Four: Penance. Without warning, Sayuri has been locked up in the Pendleton Rehabilitation Center, and no one is willing or able to tell her why. Actually, getting any information from her fellow inmates or the labyrinthine bureaucracy that runs the facility seems impossible. But is the Pendleton really a prison, or something else? Starring Natalie Morales. New episodes air daily from October 19th through Halloween. Listen to 13 Days of Halloween on the iHeartRadio app, or wherever you get your podcasts!
