“Unsolved”
The first season of “Unsolved” looks at the ins and outs of the 1976 murder of 14-year-old John Zera, but don’t be fooled: it’s easy to binge the entire season in an afternoon. With episodes ranging from 13 to 30 minutes, it’s one of the shortest podcasts out there. But take comfort in the achievement of actually finishing something for once in your life.
