Point de non-retour / Chasse à mort (Pocket Book)

The stories keep me on the edge of my seat, but I'm curious about the techniques used to maintain tension in such a compact format. Was this intentional from the start?

Many characters operate in gray areas, which made me question what I consider 'right' or 'wrong.' How did the author approach creating such complex moral landscapes?

The stories delve into dark psychological territory, and I'm wondering what personal experiences or ideas influenced these themes.
