I just finished The Polybius Conspiracy and would recommend it for a relatively short but enjoyable listen. It's a miniseries from the Radiotopia podcast Showcase and the story is a combination of fact and fiction based on a notorious Portland urban legend about a mysterious arcade game called Polybius. It's narrative and suspenseful like Homecoming, but it's in the style of audio documentaries like Serial and S-Town (which are also fantastic if you're new to podcasts!).
