La esencia del mal (Seix Barral)

The story's shifting viewpoints kept me on the edge of my seat. I'm curious whether this was planned from the start or evolved during writing.

The characters' loyalties are so murky that I kept second-guessing everyone's motives. Was this confusion intentional to reflect the espionage world?

The exotic backdrop added a unique flavor to the espionage tale. I'd love to know if the setting was inspired by real locations or purely fictional.
