Angels and Demons #4

Finally, the feared-action of the Illumnati has occurred. The first cardinal was killed and branded with the mark "Earth" exactly at 8 o'clock as the killer of Illumnati had warned. I have read up till page three hundred, and soon, the second cardinal will become the victim with a branded mark "Air" on his chest. My question is, will Langdon and Vittoria will be able to stop this misconduct and bravely confront the Illumnati?
Yes, the first cardinal was killed like what I have expected. However, my prediction was that Langdon and Vitrtorai will see the first cardinal being killed at the Pathenon except that the Illumnati will escape from the Vatican guards and Langdon and Vittoria. But there was a twist. When Langdon and Vittoria were anxiously waiting for the killer to reveal himself inside the Pathenon, they realized their flaws in their predictions. It turned out that they were at the wrong place at the last minute or few minutes before 8 o'clock. Hence, they were terrified and endeavored to go to the actual place where the murder will happen on time. However, their effort was futile because when they arrived at the Chigi chapel, it was too late for the cardinal was already dead. This twist created such suspense; it was such a surprise. I marvel at how Dan Brown engaged me into the novel, making me wait for the murder to happen at the pathenon, but making a twist and swirling and amusing my mind. Again, I certainly love these twists that Dan Brown uses. His twists never disappoint me!
While reading the book, I started feeling skeptical towards Maximillian Kohler. Once in a while, there would be short chapters about what Kohler is doing at CERN. He has left his office and intruded Leonardo Vetra's lab and room to find something. I wonder what he was scrutinizing, and I even thought and I am thinking that Kohler might be an accomplice or an associate with the Illumnati because of his suspicious actions. I even asked this question to my father who read this book before, and he gave me a small smile telling me, "You'll find out." Now that I am even more curious, I am eager to continue reading, face the twists, and find the answers.
