Círculo Diabólico

The club's sinister atmosphere is so vivid — I wonder if it was based on real groups or purely fictional creation. How did the author decide to craft this particular setting?

The story builds tension but slows down at times — I'm curious if that was intentional to deepen the psychological aspect or just natural flow.

Balancing these genres is tricky, and Straub manages it so well here. I'm interested in what guided the decision to blend these elements in this way.
