El enigma de Caín

The way the text is rearranged keeps me guessing, but I wonder if that overshadowed the actual narrative for some readers. How did others feel about the balance between puzzle and plot?

The puzzle's design is so unique and challenging—I'm curious whether this was planned from the start or evolved during the writing process. What do you think led to this inventive structure?

I loved trying to piece together the clues, but sometimes it felt like the solutions were too hidden. Did others feel the puzzle was fair or more of a riddle than a mystery?
