Die Herren der Zeit (Inspector Ayala ermittelt, Band 3)

The blending of history and fiction adds depth to the story, but I wonder if this was based on real events or pure imagination. How did the author decide where to draw the line?

The pacing felt steady, with moments of tension that made it hard to put down. Was this deliberate to enhance the mystery's unraveling?

The details felt vivid and well-researched, making the past come alive. I'm curious whether the author did extensive research or relied on personal knowledge.
