La regola del tre

The title hints at a pattern or code that drives the plot. I'm curious whether this idea was planned from the start or evolved during writing, and how it influences the story's tension.

I loved how no one was purely good or evil, but it also made me question who I was rooting for. Were there moments when expectations shifted as the story unfolded?

The atmosphere was so tense and unsettling at times — I wonder what led to the decision to blend horror with the crime genre in this way. Did it come naturally or was it a deliberate choice?
