1. Psychological Fortitude

It takes a certain type of person to be a CIA agent in Havana. Subjected to constant harassment and surveillance, it is a claustrophobic and eerie world to navigate. And when one agent hears a mysterious sound causing him real-world symptoms, it raises fears of a covert weapon. New episodes will be released weekly, wherever you get your podcasts, but if you are in the UK, you can listen to the latest episodes a week early, first on BBC Sounds.
