Angels & Demons 天使與魔鬼

The book uses a lot of religious imagery and symbolism—did that enhance the story or distract from the mystery for others?

The Vatican's depiction felt both detailed and atmospheric, but I wonder if the author had a personal fascination or specific research behind it.

The story accelerates quickly after a slow start, which worked for me, but some might have preferred more buildup—was this intentional?
