Stalking the Ripper

The narrative feels very personal and intense. I'm curious whether this was a deliberate decision to immerse the reader or if it evolved during writing.

The book delves into the mind of the killer, which added a chilling layer to the mystery. How did the author balance giving depth without glamorizing him?

The setting feels very authentic and immersive. I'm interested in whether the author relied on thorough research or if some details were invented for the story.
