Yes, if you want a quick, unsettling thriller with a genuinely distinctive antagonist and can tolerate a dark tone. Sources agree on the momentum but not on the payoff: Kirkus finds the pacing occasionally off and the final reveal shaky, while publisher-supplied blurbs are far more enthusiastic. Treat it as a strong page-turner rather than a standout of the genre.

The Sandman by Lars Kepler Review: Propulsive Swedish Serial-Killer Thriller

LuvemBooks Verdict

Best for

Readers who like Nordic crime built around a manipulative, hard-to-contain antagonist and very short, cliffhanger-driven chapters that are easy to read in bursts, ideally with some familiarity with the Joona Linna series.

Worth it if

Worth reading if you want a fast, creepy serial-killer thriller with a distinctive hook and can accept a dark, blood-soaked tone and a reveal that some reviewers found shaky.

Skip if

Skip it if you're squeamish about graphic violence and captivity themes, or want a standalone entry, since this is the fourth book and leans on Linna's earlier history with Jurek Walter.

What readers & critics say

Kirkus Reviews says fans of Kepler's detective won't be disappointed but finds it less spine-tingling than the genre's best, while reader blogs such as The Real Book Spy and Really Into This are enthusiastic about the scares and the villain. A dissenting book blog, Lit Wit Wine Dine, says it didn't live up to expectations.

Was this helpful?

The Sandman is the fourth Joona Linna thriller, built around an undercover mission inside a psychiatric ward to reach a killer whose whispering is treated as a weapon. It is a fast, cliffhanger-driven read with a memorable hook, but reviewers split on how far it rises above the genre, and newcomers will want to know it leans on earlier series history.

Is it worth reading?: Yes, if you want a quick, unsettling thriller with a genuinely distinctive antagonist and can tolerate a dark tone. Sources agree on the momentum but not on the payoff: Kirkus finds the pacing occasionally off and the final reveal shaky, while publisher-supplied blurbs are far more enthusiastic. Treat it as a strong page-turner rather than a standout of the genre.
Similar books: For another Nordic serial-killer story, Jo Nesbø's The Snowman is the benchmark Kirkus itself holds this book against, and Thomas Harris's The Silence of the Lambs is the classic of a manipulative killer questioned from behind bars. For psychiatric-setting suspense, The Silent Patient is a natural pick, while The Whisper Man shares the creepy-voice-in-your-head unease. Never Lie offers a faster, more claustrophobic modern thriller for readers who want the same compulsive pace.
Who should read this?: It suits readers who enjoy Nordic crime with a menacing, manipulative antagonist and who like chapters short enough to read in snatches. Existing fans of Joona Linna will get the most from it, since Linna's earlier history with Jurek Walter is a live part of the story. It is a poor fit for anyone squeamish about graphic violence or captivity themes.
Do I need to read the earlier books first?: It is the fourth Joona Linna novel, and it builds directly on Linna's earlier sacrifice in catching Jurek Walter. You can follow the plot without the earlier books, but newcomers may feel a step behind on the emotional stakes. Readers who want the full effect should start earlier in the series.
How violent or disturbing is it?: Quite. Kirkus uses the phrase blood-soaked, and the premise centers on a serial killer, abduction, and a locked psychiatric ward. Publishers Weekly's starred review notes the violence is unflinching but paired with real care for the characters.
About Lars Kepler: Lars Kepler is the pseudonym of husband and wife team Alexander Ahndoril and Alexandra Coelho Ahndoril, authors of the Joona Linna series.
Tell me about the adaptation: The publisher notes the novel as the inspiration for NOCTURNE, a drama described as an Apple Original series on Apple TV. Check the streaming service for current availability and details, since LuvemBooks has not reviewed the series itself.

The Sandman is a dark, fast-moving Swedish serial-killer thriller in which a young detective goes undercover inside a psychiatric hospital to get at a killer who talks his way into people's heads.

The Sandman: A novel (Killer Instinct) by Lars Kepler front cover

What the book is

Lars Kepler's The Sandman is the fourth Joona Linna novel, published by Vintage Crime/Black Lizard in this paperback edition in January 2019. Kirkus lists it as translated by Neil Smith, and the series is presented to English readers as the Killer Instinct books.

The setup is a missing-person case reopened after thirteen years. Late one night outside Stockholm, Mikael Kohler-Frost is found wandering, long after he vanished along with his younger sister.

Both had been presumed victims of Jurek Walter, Sweden's most notorious serial killer, who is serving a life sentence in a maximum-security psychiatric hospital.

Mikael tells police his sister is still alive, held by someone he knows only as the Sandman. That claim sends Detective Inspector Joona Linna back toward the man he caught years earlier at great personal cost.

The plot engine: getting Jurek to talk

Linna is convinced Jurek has an accomplice, and that the only route to the sister runs through Jurek himself. The publisher's synopsis names the one agent he believes can manage it: Inspector Saga Bauer, a twenty-seven-year-old prodigy.

She must go under deep cover on the ward where Jurek is held. The danger, as the synopsis frames it, is double: the clock on the missing girl, and a prisoner who gets inside people's heads.

Kirkus sharpens that second point. Walter whispers to anyone who will listen, and his jailers and psychiatrists wear earplugs around him.

That conceit is the novel's most distinctive hook.

How it reads on the page

The style is built on very short chapters. Kirkus describes them as mostly a couple of pages long, written in telegraphic sentences.

Shelf Awareness says the bite-size chapters end on cliffhangers.

Janet Maslin of critics called it a "nonstop fright" with tight, staccato chapters. Publishers Weekly, in a starred review, said Kepler doesn't pull any punches and that his care with characters makes readers invested in their fates.

These quotes come through the publisher's page rather than the outlets' own sites, so they are best read as promotional endorsements. They do agree with Kirkus on the basic shape: propulsive, episodic, built to be read in bursts.

Where the verdicts split

Kirkus is the most measured source. It calls the pace occasionally off and says the book resolves in a satisfactory if blood-soaked manner.

It adds that the reveal of the Sandman's identity may carry a whiff of a red herring gone bad.

It also places the novel below two benchmarks. In its view the book isn't as spine-tingling as Jo Nesbø's The Snowman or as action-packed as Stieg Larsson's original Millennium trilogy, though as Swedish mysteries go, it does the trick.

The publisher's blurbs lean the other way. Lee Child's endorsement calls it sensational, and the promotional copy compares the series favorably with Larsson.

The honest summary is that sources agree on momentum and disagree on how far the book climbs above the genre's crowded middle.

Who it is for

Kirkus says fans of the series' detective won't be disappointed, and this entry builds directly on Linna's history with Jurek Walter. Readers new to the books should know it is the fourth in the series, with Linna's earlier sacrifice a live part of the story.

It suits readers who like Nordic crime with a menacing, manipulative antagonist and short, cliffhanger-driven chapters. Kirkus's own phrase for the violence is blood-soaked, and the premise involves captivity and a psychiatric ward, so squeamish readers should weigh that.

The publisher also notes it as the inspiration for NOCTURNE, a drama described as an Apple Original series on Apple TV.

In our catalogue

The Silent Patient

Alex Michaelides

A psychotherapist digs for the truth inside a secure psychiatric unit where his patient refuses to speak — same locked-ward tension, tighter single-thread focus.

Alicia Berenson shot her husband and hasn't spoken a word since, and therapist Theo Faber takes a job at her secure unit determined to make her talk. Like The Sandman's ward chapters, the suspense comes from one dangerous mind behind a hospital door and an investigator who gets too close. It suits readers who want the psychiatric-thriller atmosphere in a leaner, single-POV package.

The Whisper Man

Alex North

A father and son are stalked by a killer echoing a decades-old serial murder case — the same mix of police hunt, dark history, and creeping dread.
