Il caso Agatha Christie

The novel offers a fresh take by focusing on her inner circle, but I'm curious whether this approach was planned from the start or developed during writing.

I loved immersing myself in the era, but sometimes I wondered if the fictional elements overshadowed the real events—what's everyone's take?

The story felt very character-driven, yet suspenseful. I wonder what techniques Nina de Gramont used to maintain that sense of intrigue.
