Self-Defense

Given that Kolde spor is a recurring element, I'm curious how it adds to the suspense or themes throughout the novel. Does it feel integrated or more like a motif?

Some chapters felt slower but atmospheric, which made me wonder if the author was deliberately pacing the story to enhance tension or character development.

Knowing this is the 9th book, I'm interested in how Kellerman decided to weave this case into Alex's ongoing journey. Was this a planned part of the series or a new direction?
