The Unseen — Mike Nicholson

When a fanatic sociopath emerges in the streets of Detroit, psychologist David Waves is drawn out of early retirement. His mission is to unlock the damaged mind of a hospital patient, a man who has killed seven people, who was the first victim of a ruthless killer, and who the police want to keep far away from David Waves. They simply don't know what David will do because it is his daughter who has just gone missing, and the clock is ticking. Now, to save his daughter, David must kidnap a killer and wade through the murky memories of a man unable or unwilling to remember. David will discover that he will need all of his resolve not only to be successful but simply to survive in a world where everyone has secrets, where everyone's motives are hidden, and where at every turn the largest threats remain unseen.
