Escrito en la sangre / The Blood Line (Nov.intrig)

The dual timelines added layers of suspense and depth, but I'm curious whether this was planned from the start or evolved during writing.

The character's relentless pursuit of truth felt intense but also a bit unsettling. How did others interpret their motivations?

The authenticity of the medical scenes really brought the era to life. I wonder if the author did specific research or if this was a personal interest.
