What's inside (9 sections)
Rachel Jenner's mistake takes four words: she lets him run ahead.
It is a Sunday afternoon in October 2012, and she has taken her eight-year-old son, Ben, and their dog, Skittle, to Leigh Woods on the edge of Bristol. She has her camera with her. The leaves are doing the thing she wants to photograph. Ben asks to go on to the rope swing alone, and Rachel, ten months divorced and tired of being the parent who says no, agrees. She follows at her own pace. When she reaches the swing, Ben is gone and Skittle is gone too. The dog turns up later with a broken leg. Ben does not turn up at all.
That is the engine of Gilly Macmillan's debut, published by William Morrow in 2015 and known in the UK as Burnt Paper Sky. It is a missing-child thriller, which is a crowded shelf, and Macmillan's contribution is to make the search feel less like a puzzle than a long exposure: the same fear, held open for 472 pages, until you can see every grain in it.
The permission is the part everyone fixes on, including Rachel. Ben had been to the swing a dozen times. He was eight, not four. She wanted him to have a little independence. That is the trap of the novel: the decision is so ordinary that any parent can imagine making it, and the public reaction is so merciless that any parent can imagine being destroyed by it.
Nine days, two voices
The book opens a year after Ben vanished, then rewinds to Day 1 and moves through nine days of investigation, one chapter per day, before an epilogue set at Christmas 2013. Rachel narrates in the first person, addressing the reader directly, sometimes asking what you would have done. Jim Clemo, the detective inspector in charge, also narrates in the first person, but his sections are framed by sessions with a psychotherapist named Francesca Manelli. We know from the start that the case has left him in pieces. We just do not know which pieces.
Between the two accounts Macmillan inserts police memos, press statements, newspaper copy, emails, blog posts, forum comments, and excerpts from books about missing and abducted children. The documents do a lot of work. They show how a case becomes a story, and how a story becomes a verdict. They also date the novel precisely: the online pile-on, the rolling news, the way a grainy clip can travel further than any correction.
Jim is the son of a detective and has recently lost his father. He is good at the job in the way that people are good at things they use to avoid thinking about themselves. He is also secretly dating Emma Zhang, a detective constable he recommends as the family liaison officer for Rachel and John. Their relationship is not a scandal, exactly, but it is a complication, and Macmillan uses it to put a fracture line under the investigation from the first day.
His boss is Detective Chief Inspector Corrine Fraser, who is competent and impatient and has no interest in Jim's feelings. Justin Woodley is the rookie who does the legwork. Mark Bennett is the colleague who keeps turning up at the wrong moments.
The press conference
On Day 3 the police put Rachel and John in front of cameras. Jim has written a script. Rachel is supposed to read it, appeal for information, and look like a mother the public will sympathy for. Instead she goes off script. She looks into the lens and tells the person who took her son that she will find him, that she will hunt him down. A cut on her head, from searching the woods, has started to bleed, and a reporter points out that her hands are covered in blood. By the evening the clip is everywhere.
The public turns. First there is sympathy, then suspicion, then something uglier. Rachel is not composed enough, not grateful enough, not maternal enough. She is too angry, too strange, too obviously guilty of something. Someone spray-paints BAD MOTHER on her back fence. Someone throws a brick through her living-room window; John runs out after the vandal and is found unconscious, kicked in the head. Rachel's best friend Laura, a gossip columnist, is pushed out of the house because Rachel suspects her of leaking details. She is wrong about Laura, but by then wrongness has become a habit.
This is the strongest sustained section of the novel. Macmillan is very good at the texture of a life under siege: the reporters camped on the pavement, the takeaway containers, the way Rachel checks the internet at four in the morning even though she knows it will make her feel worse. The blog posts are convincing, and so is the casual cruelty of strangers who have decided that a woman's face is evidence.
It is also where the book starts to repeat itself. Rachel reads something awful, reacts, is comforted, reads something else. The middle hundred pages circle the same wound. For a while the exhaustion works. After the fourth or fifth round of internet vitriol, it starts to feel like the novel is treading water while the plot waits for Day 9.
Everyone becomes a suspect
The investigation churns through men. Edward Fount, a fantasy role-player found near the woods, will only answer questions as a member of the Knights of Isthcar. The writer of a poison-pen letter to Fraser turns out to be a dying cancer patient with a grudge against John. Lucas Grantham, Ben's new teaching assistant, has a false alibi because he was riding his bicycle in the woods. Lucas is arrested on Day 8, and for about twenty pages the book lets you believe he is the answer.
Then there is Nicky. Rachel's older sister is the first person through the door after Ben disappears, and she takes over. She cooks, she fields calls, she organizes the search, she sleeps on the sofa. She is also strangely intense about Ben. She has four daughters and a husband named Simon, and she has been living apart from all of them for a month, in a cottage in Pewsey Vale that their aunt left her. Rachel does not know that. Jim finds out from Simon, and the shape of the case changes.
Nicky's red herring is effective because it is built out of real affection. She is not a cartoon villain. She is a woman who has spent her life managing other people's crises, and the novel lets you see how that habit could curdle into something possessive. Jim becomes convinced she took Ben. He is wrong, but the reader understands why he believes it, which is more than can be said for a lot of thrillers.
The Bowness file
The family secret arrives on Day 5, and it is a big one. Jim and Emma come to the house to ask Nicky about a couple named Andrew and Naomi Bowness. Rachel has never heard the names. Nicky resists, then tells the truth: those were their parents. Rachel and Nicky were born Katy and Alice Bowness. They had a brother, Charlie, who had a rare degenerative disease and who looked uncannily like Ben. Their parents killed Charlie and then themselves, and an aunt renamed the girls and raised them under new identities to spare them the stigma.
Rachel's reaction is not relief. It is vertigo. Her childhood, her name, her sense of who she is, all of it turns out to have been assembled by other people. Nicky has carried the secret for decades, which explains a great deal about her need to control Rachel's life. It does not explain everything, and Macmillan knows it. The scene where Nicky admits she thought Rachel was too weak to raise a child is one of the best in the book, because it is both a confession and a fresh wound.
The Bowness backstory is also where the novel risks tipping into melodrama. A dead brother who looks like the missing boy, a murder-suicide, a name change, a cottage in the countryside: it is a lot of gothic furniture for a book that has otherwise been careful to stay in the ordinary world. The coincidence of Ben's resemblance to Charlie is doing enormous work, and the novel never quite persuades me that it needed to. But the payoff is real. When Jim looks at Nicky and sees a grieving sister with a dangerous attachment, the reader has to weigh the same evidence he does. That is the point of a good red herring, and this one earns its place.
The family liaison officer
Emma Zhang is the other fracture line. She is Jim's girlfriend, she is Rachel's lifeline, and she is leaking. The leak is not political. Emma has been feeding confidential details to the vigilante blogger who has made Rachel's life hell, and she has been doing it because she believes Rachel was negligent. Her reasons go back to her own childhood. When she was six, she was left in charge of her two-year-old sister. She left the room for a few minutes, and the child suffocated between the bed and the wall. Her father blamed her. Emma has spent her adult life punishing women who she thinks fail to protect their children.
When she confesses, Jim does not shout. He goes cold. He refers her to Fraser, and internal affairs walk her out of the building. Later she writes him a letter explaining all of it, and he reads it and finds a bottle of whiskey and drinks until he passes out. It is a bleak, believable end to a relationship that was already running on fumes.
Jim's own history is threaded through the therapy sessions. His father, Mick, was a detective too, and a violent man. Jim has spent years telling himself that his father was simply old-fashioned, that all parents hit their children, that the job required a certain hardness. Then a memory surfaces: Jim at eight, watching his father force a girl into a car with a man, his sister Becky screaming at their father, Jim smashing a porcelain dog to create a distraction. The memory does not solve anything. It just makes Jim's obsession with Ben legible.
The therapy framing is one of the novel's best decisions and one of its frustrations. Manelli is a sharp, patient presence, and her notes are used to show what Jim will not say aloud. But Jim spends most of the book refusing to engage, which is psychologically accurate and narratively tiring. His breakthrough is small: he admits he still loves Emma, he admits he was too hard on himself, he says he will try. That is all. Macmillan does not give him a cure, and I respect that, even if the sessions sometimes feel like a device for withholding information rather than revealing it.
The nunny
Day 9 is the best sequence in the book. Jim and Woodley drive to Nicky's cottage to break her, and they are close when Fraser calls them back. Rachel, meanwhile, goes to headquarters to demand news. In the foyer she runs into Joanna May, Ben's teacher, who is also waiting for a lift after an interview. Bennett drives them both. Joanna is kind. She says how hard it must be for Ben to settle at night without his nunny.
That is the slip. Nunny is Ben's security blanket, a shameful secret he has never told anyone outside the family. Rachel goes still. When Joanna gets out of the car, Rachel knocks her handbag open, scrambles to pick things up, and steals her house keys. Then she tells Bennett her suspicion. He says he will pass it on. She goes home, takes a kitchen knife, slips out the back away from the press, and runs to Joanna's house.
What she finds is worse than an empty room. There is a packed suitcase on the bed. There is a locked door in the basement. Behind it is a bedroom decorated for an eight-year-old boy, with the wrong colors and a sports theme Ben would have hated. The laptop is smashed, and there is a dent in the wall. Ben is not there. Rachel calls the police and then goes into shock.
Ben is found that same day in Leigh Woods, near the place where he disappeared. A walker sees a boy on the ground, covered with a garbage bag, barely breathing. He is in a hypothermia-induced coma. He is taken to Bristol Children's Hospital, where Rachel is allowed to see him. He wakes. He hugs her. He is not the same child.
Joanna is arrested at Bristol Airport. Her parents, Geoff and Mary May, tell the police she was a controlling, lying child who could not conceive and who had always wanted a baby of her own. Their alibi for the afternoon of the abduction was vague; they could not remember what time she left. Joanna pleads guilty and refuses to explain anything. She is convicted, and she takes the details with her.
Rachel reconstructs the rest. Joanna approached Ben at the rope swing. Ben went with her willingly because he trusted his teacher. There was a change of clothes in the car. When Skittle tried to follow, Joanna kicked the dog and broke her leg. She kept Ben in the downstairs bedroom, gave him a computer to keep him quiet, and panicked when he managed to get online. Then she decided to abandon him where she had found him and leave the city. It is a plausible story, and it is only a story. Ben will not talk about the nine days, and the novel does not pretend to know what happened inside that room.
What the ending refuses to give
The epilogue is set at Christmas 2013, a year and five weeks after the abduction. Joanna is in prison. Ben is home, but he is guarded and withdrawn. He does not understand why his parents and the police did not find him sooner, and he cannot square the teacher he adored with the woman who took him. John and Katrina have a baby girl. Ruth, John's mother, has been told what happened and has reconnected with Ben. Ben has taken up the violin and turns out to have a real gift for it. Rachel is trying to rebuild a life that will never be the one she had before.
Jim visits to explain to Ben that everyone did everything they could. He cannot tell whether Ben is ready to hear it. Later he emails Rachel to say that no one could have prevented what happened. In his last session with Manelli he says he still loves Emma and wants to be less critical of himself. Manelli tells him he will have to trust her if the therapy is going to work. He says he will try.
That is the ending: a few small repairs, no catharsis. Rachel even says as much, in one of the novel's most honest lines, that she wanted catharsis too and there was none. The American title points at the quieter knowledge she recovers, that she was not the negligent mother the internet decided she was. The UK title, Burnt Paper Sky, fits the autumnal gloom better. Neither title promises a thriller that ties everything up, and the book does not.
The biggest weakness is Joanna. She is offstage for most of the novel, and when she finally arrives she is a collection of symptoms: controlling, infertile, prone to lies. Her parents explain her, and Rachel's reconstruction explains the mechanics of the crime, but nobody really explains the why. After 472 pages of grief and speculation, the villain feels thinner than the red herrings. That may be deliberate. Macmillan is more interested in the damage than the diagnosis. Still, readers who want a satisfying answer to the mystery will close the book with a question mark.
The middle sags, too. The day-by-day structure is a clever way to create pressure, but it also means the novel has to fill nine days, and some of those days are filled with another interview, another blog post, another false lead. Edward Fount and Lucas Grantham are believable distractions, but they are distractions, and you can feel the book marking time before the real clue arrives. The final act also depends on a lucky slip and a stolen set of keys, which is a lot of chance for a case that has been built on procedure.
And yet the book got under my skin. Rachel is not always likable. She snaps at the people helping her, she uses Ben to confirm her grievances about John, and she spends a lot of the novel convinced that her ex-husband's new wife is a cartoon stepmother. Macmillan does not excuse any of it. She just keeps the camera on her, and the accumulated detail does what the plot cannot: it makes the loss feel specific.
This is not a book for readers who want a clean whodunit, a heroic detective, or a villain with a fully explained psychology. It is for readers who want the mother's interior life to be the main event, who can tolerate a procedural that is more interested in fatigue than in forensics, and who do not need the last page to feel like relief. The last note is not a resolution. It is a boy who would not talk about nine days of his life, learning to make music. The book leaves it there.
