《天使与魔鬼》的创作灵感来自于作者的一次梵蒂冈之旅。丹·布朗在游览梵蒂冈的地下通道时得知，这个秘密地道就是早期的天主教教皇躲避敌人追赶时的藏裑之所，而几百年前，最让梵蒂冈畏惧的敌人就是一个名为“光照派”的秘密组织。这个组织由一些受到宗教迫害的科学家组成，他们发誓要对梵蒂冈进行复仇。时至今ㄖ，当代许多历史学家还对这个组织的存在深信不疑……丹·布朗受此启发，创作出这部以科学和宗教的关系为主题的惊悚悬疑小说。
继《达·芬奇密码》、《数字城堡》引进慖内后，人民文学出版社隆重推出悬疑大师丹·布朗最扣人心弦的力作《天使与魔鬼》，宗教与科学的激烈对抗，人忄生与神忄生的正面碰撞，拿起来就再也放不下的神奇之作。
It takes guts to write a novel that combines an ancient secret brotherhood, the Swiss Conseil Européen pour la Recherche Nucléaire, a papal conclave, mysterious ambigrams, a plot against the Vatican, a mad scientist in a wheelchair, particles of anti-matter, jets that can travel 15,000 miles per hour, crafty assassins, a beautiful Italian physicist and a Harvard professor of religious iconology. It takes talent to make that novel anything but ridiculous. Kudos to Dan Brown (Digital Fortress) for achieving the nearly impossible. Angels and Demons is a no-holds-barred, pull-out-all-the-stops, breathless tangle of a thriller--think Katherine Nevilles The Eight (but cleverer) or Umberto Ecos Foucaults Pendulum (but more accessible). Harvard symbologist Robert Langdon is shocked to find proof that the legendary secret society, the Illuminati--dedicated since the time of Galileo to promoting the interests of science and condemning the blind faith of Catholicism--is alive, well, and murderously active. Brilliant physicist Leonardo Vetra has been murdered, his eyes plucked out and the societys ancient symbol branded upon his chest. His final discovery, anti-matter, the most powerful and dangerous energy source known to man, has disappeared--only to be hidden somewhere beneath Vatican City on the eve of the election of a new pope. Langdon and Vittoria, Vetras daughter and colleague, embark on a frantic hunt through the streets, churches and catacombs of Rome, following a 400-year-old trail to the lair of the Illuminati, to prevent the incineration of civilisation. Brown seems as much juggler as author--there are lots and lots of balls in the air in this novel, yet Brown manages to hurl the reader headlong into an almost surreal suspension of disbelief. While the reader might wish for a little more sardonic humour from Langdon and a little less bombastic philosophising on the eternal conflict between religion and science, these are less fatal flaws than niggling annoyances--readers should have no trouble skimming past them and immersing themselves in a heck of a good read. "Brain candy" it may be, but its tasty.
