Books by John Katzenbach

A recovering alcoholic stalks his uncle's murderer in this tale of revenge, psychosis and homicide.

Not all fairytales have a happy ending... A gripping psychological thriller that you won't be able to put down. Perfect for fans of The Girl Before and I See You. 'You do not know me, but I know you. I have decided to call you: Red One. Red Two. Red Three. I know each of you is lost in the woods. And just like the little girl in the fairy tale, you have been selected to die...' Karen, Sarah and Jordan have nothing in common aside from their hair colour. Red. To the man who has been watching their every move for months, this is enough. Their lives are now in his hands, their stories will only end when he chooses to reveal himself, unless they can find him first...

When the body of a young female nurse is found horribly murdered in the Western State Mental Hospital, Massachusetts, there is apparently no shortage of suspects - a whole hospital of them.

If you are unable to purchase the ad as described, then you will have this choice: kill yourself immediately or I will destroy one of these innocent people.'Until the moment he opens the letter, New York psychologist Dr Frederick Starks has led a quiet and, so he believes, blameless life.
