Wealth, thrill, the net closing in around a somewhat likable protagonist, and the gamification of murder come together in Brian Parkin’s Manifesto for a Serial Killer. Jessica Harper, a wealthy 23-year-old Australian socialite, has killing as her major hobby. A formidably intelligent and driven woman, self-taught in coding, hacking, and various other useful skills, Jessica designs an app, the Manifesto, to generate a series of random targets, murder weapons, locations, murderer characteristics, and budgets for each kill such that the cases are wholly unconnected. Detective Inspector Rob Franklin and Detective Sergeant Leanne Wilson stumble onto her trail and attempt to prove her guilt in over twenty cases of serial killing that have occurred in the entire continent of Australia.
