I bought this one originally because it was featured in Paperbacks From Hell by Grady Hendrix. Synopsis: Two men in the same One Joseph Kallinger was a superb craftsman, a sensitive poet, a devoted family man, and a human being who held all life sacred. The other Joseph Kallinger was a lover who needed images of bloody violence to maintain his sexual potency, and a father who physically tortured his children, lived in abnormal intimacy with his daughter, and enlisted his 12-year-old son in a campaign of rape and murder that terrified millions. This is the true story of Joseph Kallinger - both of him.
