Dr. Hans Vigo has done it all--he's been a profiler, taught at Quantico, and was an assistant director at FBI headquarters. He's been a character--on or off the page--in virtually all of my books, starting with the first THE PREY. Hans was the character who was always supposed to die … but I never was able to kill him off. I fully intended to kill him in KILLING FEAR, but couldn't bring myself to do it. He's been a mentor to many of my FBI characters, including Megan Elliott (SUDDEN DEATH) and Kate Donovan (FEAR NO EVIL.) Because of their similar backgrounds in psychiatry, and a mutual respect, Hans and Dillon Kincaid have become close friends.
