Girl Unknown - Schwester? Tochter? Freundin? Feindin?: Roman

The suspense hinges on not knowing who to trust, but I wonder if this was planned from the start or evolved during writing. How did the author approach maintaining this mystery?

The rapid shift from camaraderie to suspicion made me question how fragile relationships can be under pressure. Was this an intentional commentary on psychological manipulation?

Balancing moments of quiet introspection with high-stakes scenes is tricky. I'm curious about how pacing choices contributed to the overall suspense.
