De geheime oorlog: Spionnen, codes en verzet: 1939-1945

His detailed account sheds light on hidden operations, but I wonder what motivated him to bring these stories to the forefront.

The book dives deep into codes and clandestine missions, and I’d love to hear if others found the technical details clear or overwhelming.

The mix of strategic overview and individual espionage tales made the history feel more tangible, but I’m curious about the author’s approach to this balance.
