El secreto del alquimista

The blend of real historical elements with fiction added a layer of intrigue. I wonder what sparked the idea to weave alchemy into this modern mystery.

While I appreciated the depth, I found myself wanting more of the action. Was that balance intentional or did it evolve during writing?

The shifts between past and present kept me engaged but also a bit confused at times. I'm curious whether this was planned from the start or developed later.
