Schlaflos: Psychothriller (Die Profilerin 3)

Camilla Grebe's use of chilling locales really heightens the suspense. I'm curious what influenced her choice of setting and mood.

The characters felt complex and unpredictable, which added to the mystery. Did others find themselves guessing what drove them?

The story moved at a steady pace, but I wondered if that was deliberate to mirror the psychological unraveling. Would a faster pace have changed the impact?
