オスロ警察殺人捜査課特別班　フクロウの囁き (ディスカヴァー文庫)

The mood really drew me in, but I wonder what influenced the author's approach to building such a haunting atmosphere throughout the novel.

I was struck by how deeply the characters' psychological struggles felt integrated into the story. How did the author balance character arcs with the suspenseful plot?

The icy, isolated backdrop added so much to the suspense. I'm curious whether the setting was inspired by real places or was purely fictional.
