Der Sarg des Griechen (Taschenbuch)

The story's locked-room setup and the clues are so tightly woven. I'm curious whether the puzzle was designed first or evolved during writing.

The buildup took a while before the real suspense kicked in. I'm wondering if that was intentional to add atmosphere or just a stylistic choice.

The classical elements added a unique flavor to the story, but I wonder whether it was chosen for atmosphere or thematic significance.
