Apnea (Le inchieste di Sam Berger e Molly Blom Vol. 3)

The story keeps me hooked but also slows down at times — was this deliberate to deepen character development or to heighten tension?

The cold, stark environment seems to reflect the darker themes; I'm curious if the setting was inspired by real locations or fictionalized for mood.

The multiple viewpoints added layers to the mystery, but I wondered whether this was planned from the start or evolved during writing.
