Though he's a Chicago native, Thor has spent a lot of time in Manhattan promoting his books and happily taking in the sites, but he said he came to see the island a bit differently while working on 'Takedown,' a book inspired by alleged plots to perpetrate a Mumbai-style assault on Midtown. "When I came to New York as a writer, I was taken with the idea that you're only getting in on bridges and ferries and through tunnels," says Thor. "The idea behind 'Takedown' is that it would be very hard to get out."

In order to get a sense of how alert New Yorkers really are to threats, Thor says he watched to see how often people looked up from their phones and left an empty bag in a hotel lobby to see if security would remove it. "Nobody noticed the bag. People are careless about that stuff."
