The Quiller Memorandum

The setting feels so authentic and tense—did the author base it on real locations or personal experiences? I wonder what drew him to this backdrop.

The story builds up to such a tense climax, but the middle parts felt a bit slower. Was that intentional to develop the characters or atmosphere?

His guarded nature added so much depth, but I’m curious whether this was based on real spy archetypes or purely fictional creation.
