The best true crime podcasts bring us into investigations ears-first. They make us feel like we’re truly involved. Few series do this as spectacularly as Cold. Susan Powell disappeared in 2009 and, while her husband Josh was a suspect from the outset, he was never charged or arrested and her body has never been found. Over eighteen hour-long episodes and three comprehensive bonus add-ons, Dave Cawley breaks down the case in granular detail. This is no true crime quick fix. Stories like this one take time.
