Angels and Demons by Dan Brown (2000) A Corgi Book

Robert Langdon is at it again.  The professor is called early in the morning and invited to Cern in Switzerland.  There is an extraordinary jet waiting for him that gets him to Cern in an hour out of Boston.  There he is asked to look at a dead man because of what happened to him.  He was murdered and branded with a Illuminati done as an ambigram; it can be read upside down or right-side up.As usual there is a beautiful, vulnerable, and strong woman at his side throughout the story.  In this case, she is the victim’s daughter.  There is also a memorable directory of CERN, and the key players in Rome as they prepare to elect a new Pope.

Brown certainly leads the story with almost constant rising action, never letting Langdon have a moment to relax.
