Alex Cross is a detective and forensic psychologist, uniquely capable of digging into the psyches of killers and their victims, in order to identify - and ultimately capture - the murderers. He is brilliant, flawed, and full of contradictions. A doting father and family man, Cross is single-minded to the point of obsession when he hunts killers. He is desperate for love, but his wife's murder has left him too damaged to receive it.
