I wonder how many avid readers of Daniel Silva's Gabriel Allon novels could hear the reports of the arrests regarding a plot on the Pope's life without thinking of those thrillers, some of which involve terrorist threats against the Pope.
If you have not read the novels, I recommend starting at the beginning. [A button for the first novel - The Kill Artist - is currently on the right side of this page.] The series is extraordinary.
