Vatican Bombing?

Author's Note: This is my prediction piece for the book, Angels and Demons.   Below is the scene I am predicting will happen sometime during the book.

I predict the Illuminati will bomb St. Peters Basilica with a time bomb.  On the cover of the book, it shows the inside of St. Peters Basilica and directly below it is an explosion with digital numbers. The digital numbers is like a timer going down.  Also, a murder has already occurred, which leads me to believe there is going to be a big firefight between the people that killed the man (the Illuminati) and Dr. Langdon and his allies for two reasons.  One, there is already a history of violence within the books, and two because in some books, such as Patriot Games, the main character is indirectly associated with the bad guys, and end up fighting them in the end.

Scene:

Bullets flew everywhere, occasionally finding their target.  The guards were taking heavy casualties and were slowly being pushed back deeper and deeper into the church.  In a matter of minutes, the guards were forced to retreat all the way into center of St. Peters Basilica.  Once within, everything became silent.  Anxious, the guards started to shuffle, but seconds later, a loud beeping was heard, freezing everyone in the room.  The beeping started slow but grew faster and faster until it was just one continuous beep.  That's when the bomb went off.  An earsplitting explosion jarred the entire church.  Huge pieces of plaster rained down on the remaining guards, instantly burying them alive.  St. Peters Basilica famous dome shuttered and finally caved in on itself.
