They feared the machines.
They should have feared the people…
London, Christmas 1999. The world is on edge. With the new millennium just days away, fears of the Millennium Bug are spiralling – warnings of computer failures, market crashes, even global catastrophe. But fifty miles east, on the frozen Blackwater Island, a different kind of mystery unfolds. A child’s body is discovered on the bracken, untouched by footprints, with no sign of how he died. And no one has come forward to claim him.
At the International Tribune, reporter Jonny Murphy senses something is off. Police are appealing for relatives, not suspects. An anonymous call led officers to the scene, but no one knows who made it. While the world fixates on a digital apocalypse, Jonny sees the real disaster unfolding closer to home. With just twenty-hour hours before the century turns, he heads to Blackwater – driven by curiosity, desperation, and the sting of rejection from his colleague Paloma.
But Blackwater has secrets buried deep in the frozen ground. More victims – some dead, others still paying for past sins. And when Paloma catches up to him, they stumble onto something far bigger than either of them imagined. Something that could change everything. The millennium is coming. The clock is ticking. Can Jonny stop it? Should he?
And what if Y2K wasn’t a hoax, but a warning…?
Sarah Sultoon’s Blackwater is an apt December read. The story is a race against the turn of the millennium. The novel is set in late December 1999 in London and the surrounding Essex wetlands of the Blackwater Estuary. Sultoon balances historical tension with sharp pacing to produce a thriller that resonates.
In addition to being the name of an Essex Nature Sanctuary known for its oysters, Blackwater is, of course, the former name of an existing American private military contractor founded by an ex-Navy SEAL officer. A private army that the US government quietly hired to operate in international war zones, which has been involved in several scandals. That fact lingered in the background as I read this book.
The background to the novel – the fear over what Y2K might bring – is not just window dressing; it embodies uncertainty and feeds our deeper anxieties — something the book uses to terrific effect.
From the first page, the pace is propulsive. The discovery of a child’s body on remote Blackwater Island — with no sign of footprints, and no identity for the child – launches Jonny Murphy, a reporter at the International Tribune who’s tired of forever writing dull Y2K dispatches, into the story. What he finds are chilling secrets, and very high stakes.
Sultoon’s plotting is as tight as a drum; lean and spare. Events escalate with mounting tension, and each chilling revelation is a shock that propels you onto the next.
Jonny himself is a compelling and flawed protagonist. Weighed down by memories of his professional disappointments, he has an easily bruised ego, especially when it comes to his relationship with Tribune photographer, Paloma. Their dynamic is more than a tentative partnership; it’s grounded in mutual respect and unspoken feelings. When Paloma catches up to him on Blackwater, the tension between them evolves into a partnership that grows under pressure.
As a journalist, Jonny’s position at the International Tribune plays into every choice he makes. He’s not just chasing headlines; he’s wrestling with his conscience, his urge to follow the story, and the need to prove himself. His internal conflict informs his decisions in ways that go beyond the usual ‘follow the clues’ instinct; he pushes into danger not because it’s dramatic, but because it’s how his personality is forged.
Sarah Sultoon creates a vivid sense of place: the bleak Blackwater Island and its surrounding marshes are cold and unforgiving, sharpening the novel’s already chilling tone and enhancing the dread at the story’s core.
The millennial concerns that I remember so well are cleverly interwoven with political intrigue and local mysteries. There are creepy figures; Jane Doe, a witchlike GI Jane and Judith, the landlady of the local pub, The Saxon, who is quite the character and Jonny doesn’t know what to make of her.
Then there’s DI Gillian Peters, the only police presence in the area, with so few resources, she doesn’t even have an official police car. Her hopes of having the investigation into the child’s death properly resourced are unrealised. It’s clear to her that this death will go unresolved unless she can somehow raise the profile of the body’s discovery, and in Jonny she sees a way of getting the help she needs.
Blackwater is taut, atmospheric, and emotionally engaging, authentically evoking late 1999. It captures a time when the world feared computers crashing (I remember worrying about being on a flight so close to midnight on 31st December), yet remained blind to the many killings going on at the same time. It’s the kind of thriller that stays in the mind — not just for its countdown clock, but for how it makes you feel the burden of its characters’ choices.
What makes it so fascinating is not just the plausibility of the storyline, but in the author’s afterword. Sarah Sultoon lays out the facts that appear in the book, showing us just how close to very real danger we came.
Blackwater is perfect for fans of gritty crime and tightly woven suspense.
