Сердце убийцы

Cain's depiction of the mental toll on the detective felt so visceral. I wonder what inspired her to explore this aspect of obsession and trauma?

The story had an intense opening and ending, but the middle chapters felt a bit slower. I'm curious if this was deliberate to deepen character development.

Seeing into the mind of the antagonist added a disturbing layer, but I wonder how this decision impacted the overall suspense and reader engagement.
