The Bali, Paris, Saigon, Tokyo, Los Angeles, Bay Area, New York, Singapore, Rotterdam, and Amsterdam locales that appear in this book are described, as always, as I have found them. The nonlethal millimeter wave “area denial system” technology Rain and Boaz use in Singapore is real, but I don’t know if there are yet versions as portable, or as able to penetrate walls, as the one in this book.
