De Vijf en de spooktrein

The pacing kept me eager to see what would happen next, but I wonder if the adventure was planned from the start or grew during writing. Did the setting influence the story's energy?

The descriptions of the camp and outdoor fun brought back memories for me. How do others connect with the sense of childhood freedom in the story?

The friendship between the five is so lively and genuine. I wonder if Blyton based them on real kids or if they evolved during the writing process.
