La noche de los cuchillos

The story's grim atmosphere really immerses readers in a dangerous world. I'm curious if this tone was inspired by specific mythologies or personal preferences.

Many characters seem to operate in shades of grey rather than clear-cut good or evil. How did the author decide to develop such layered personalities?

The events feel tightly packed, creating a sense of urgency. Was this structure planned from the beginning or did it evolve during writing?
