The Bottom Line: A dark, propulsive origin story that pits a newly minted detective against the kind of evil that doesn’t stay buried. Maddy Reynolds is a heroine built to last.
Set primarily in late-1970s upstate New York, Deranged introduces newly promoted detective Maddy Reynolds. Following in her father’s footsteps, who was fatally stabbed by an uncaught serial killer, Maddy investigates the disappearance of an eleven-year-old girl. The early investigation reveals a broken family: a neglected child, a mother undone by alcohol and bitterness, and a father who has moved into another life. Maddy interviews the girl’s mother, her father and his fiancée, and a neighbor whose kindness gives the disappearance a sorrowful human dimension. But the discovery of an old valentine signed by someone unknown to the family pushes the case beyond a runaway report, suggesting that Sarah may have been groomed before she disappeared.
Author John Netti then takes us to 1950s London, where a teenaged boy named Nigel is brutalized by his mother and tormented by his sister Gertie. He retreats into rocks, chess, secrecy, and calculation before discovering Gertie’s peanut allergy. He then studies the household routine, contaminates her cereal, and lets her die while preserving the appearance of an accident.
The Nigel chapters give the novel a psychological chill that sits beside its police-procedural structure. Netti is not content simply to present a monster and set a detective after him. He traces the habits of mind that make the monster possible: grievance, humiliation, secrecy, strategic patience, and the thrill of control. That emphasis gives the book a darker texture than a straightforward missing-child thriller.
Meanwhile, Maddy’s arc gives the novel its emotional center. She is capable and determined, but Netti does not make the mistake of presenting competence as invulnerability. Her promotion carries the weight of history: she is the first woman detective in the department, a single mother, and a daughter still living with the consequences of her father’s murder. The case tests each part of that identity. At work, she has to prove herself in rooms where skepticism is often assumed before respect is earned. At home, her daughter Amber reminds her that the victims she investigates are not abstractions. They are children close enough in age and vulnerability to make every lead feel personal.
Netti’s prose is strongest when it pays attention to procedure without letting procedure flatten the human stakes. Interviews, crime-scene work, departmental briefings, and suspect leads are balanced against private moments of exhaustion, memory, and dread. The book also has a strong sense of concealment. People are not always what they appear to be, domestic spaces may hide damage, and ordinary objects can become sinister when placed in the wrong hands.
Deranged works as both origin story and self-contained thriller. Readers should expect a bleak serial-killer narrative involving crimes against children. But for readers drawn to psychologically charged crime fiction, police procedurals, and suspense built around damaged pasts returning to the present, Netti offers a controlled and persuasive start. Deranged succeeds because it understands that the most frightening cases are not only solved in squad rooms and crime scenes. They are also fought inside memory, conscience, and the promises people make before they fully understand their cost.
