3D-printed sleeping figure with a rust-stained axe, inspired by The Sleepwalker by Lars Kepler

The Sleepwalker – Lars Kepler

Chapters Unbound: Episode 29

A chilling opening that pulls you straight into the nightmare

The novel drops you onto a frozen campsite in Bredäng, just outside Stockholm. Suddenly, an alarm shatters the dead‑of‑night silence. Police spot a weak glow coming from a remote caravan. Inside, the scene is grotesque… Blood splatters every surface, furniture is ripped apart, and an axe is lodged in a heap of mutilated flesh.

Meanwhile, a teenage boy emerges from the wreckage. He is later identified as Hugo Sand, the son of a celebrated author. Hugo lies on a severed arm that serves as a makeshift pillow. He suffers from a rare, nightmare‑triggered sleep‑walking disorder. Consequently, readers wonder whether he is the murderer, a silent witness, or merely a victim of his own subconscious. His adamant claim of total amnesia adds tension and drives the investigation forward.

Detective Joona Linna, ever the relentless sleuth, enlists her trusted colleague Erik Maria Bark. Together they turn to hypnosis in a desperate bid to extract any fragment of memory from Hugo. What follows is a relentless cat‑and‑mouse chase that pits the detectives against a cunning, seemingly unstoppable serial killer.

The severed head and the weapon

For this episode I printed the exact moment after the crime. A decapitated head sits beside the blood‑stained axe that delivered the fatal blow. The head’s mouth is agape, its eyes wide open in a frozen gasp of shock. I deliberately left the textures uneven and the surface pale to convey brutal clarity between act and aftermath.

I didn’t aim for shock value, although the image certainly contains it. Instead, I wanted to capture the instant where everything has already happened, yet the expression hasn’t caught up to the surrounding silence. The rough skin, the tightened jaw, the pale surface, nothing is softened, nothing is polished.

Anyone who has read the book will recognize the tension without further explanation. Otherwise, the viewer simply sees what remains when the night refuses to let go.

When sleep becomes a sentence

The Sleepwalker blurs the line between unconscious wandering and responsibility. So, who are you when your body acts without conscious permission? Joona Linna keeps asking whether any innocence can survive an act carried out in a nightmare‑driven trance. My sculpture answers in a hushed whisper: perhaps not.

The book keeps circling the same question: How much responsibility survives a blank space? This print carries that same uncertainty. The axe and the head don’t explain anything; they leave you with the quiet weight of what can no longer be undone.

What stayed with me

It isn’t the gore that haunts me; it’s the question of memory. How much of what we forget is mercy, and how much is self‑preservation? That thought clung to me long after the printer cooled down.
