Where did you get the idea for your most recent book?
The Hollow Man is based on true events during the early 1970s, and traces some of my experiences as a young man traveling in Europe. At the time, terrorism was on the rise and I had been assigned to learn as much as I could about it. Most early acts of terrorism were specific to political and social leaders who represented offending ideologies. But terrorism was beginning to change its strategy to the familiar, senseless chaos we recognize today. The death of political figures no longer seemed to bother us as much as these new, random attacks against our children. Targets of innocence became preferable because they hit closer to our hearts and the fear inside us grew larger with each incident.
