Die Augen der Katze

The detailed backdrop adds so much atmosphere, but I'm curious whether the author knew the location well or did extensive research. How did the setting shape the characters' choices?

The chemistry between the characters felt authentic, even when danger was at every turn. Did others find the romance to be a slow burn or more immediate?

The story seamlessly weaves suspense and romance, but I wonder if that was intentional from the start or evolved during writing. What do you think was the main focus?
