The story's first mystery lies in uncovering who is responsible for the "murderous rampage": is it the title character, Adrian, who suffers from a combination of what appears to be bipolar affective disorder and a childhood trauma-based dissociative disorder, modified by substantial quantities of alcohol? Is it his long-estranged brother, who has basically the same maladies? We are teased with the interspersed journal of a megalomaniacal psychopath, "Madman," who alternately philosophizes on the ills of society, exhorts parents on how to better raise their children, and seethes with hatred and revenge for the police who are tracking him down. This mystery is resolved by the tenth of 24 chapters.
