The Valhalla Exchange

The blend of real historical events with fictional intrigue adds depth to the story. I'm curious whether the setting was chosen to highlight specific themes or for narrative convenience.

The characters' loyalties kept shifting, which made me wonder how much of that was inspired by real spy tactics. How did others interpret the authors' depiction of loyalty under pressure?

Switching between characters added layers of complexity but also made me work to keep track of everyone. I'm curious whether this was planned from the start or evolved during writing.
