I don't know if I can bring myself to finish reading Angels & Demons. Here's a guy who is writing about stuff that would take tons of knowledge and research. He's got Illuminati, history, art, religion, and some damned complex science. Then his characters are being searched by the elite Swiss Guard, who is satisfied they are not a threat after listening for a dial tone on the woman's cell phone. A dial tone. On a cell phone. I don't think I can buy into the rest of the book.
