David Lagercrantz’s New Hans Rekke Novel Revisits a 1988 Santander Murder Through a Chilling Literary Echo

David Lagercrantz’s next Hans Rekke novel returns to a murder that has haunted Santander, Spain, for two decades, linking a 1988 killing to a story of fiction, violence, and detection with echoes of Sherlock Holmes. The book, translated by Ian Giles and set for release on Aug. 25, 2026, continues the procedural series that began with Dark Music in 2022.

The case centers on 20-year-old Sandra Ramirez, who was savagely kicked to death and left beneath an old oak tree in Santander. The killing remained unsolved for 20 years, but the crime carries an eerie literary dimension: Ramirez had written a short story told from the perspective of a stray dog that dies under that same oak tree. That coincidence gives the novel a striking premise, tying the investigation to an unsettling overlap between imagination and reality.

In 2008, master detective Hans Rekke and police constable Micaela Vargas reopen the cold case, and the inquiry quickly proves more dangerous than it first appears. The pair’s work eventually puts both of them in serious jeopardy, suggesting that the murder is not simply a matter of historical reconstruction but part of a wider pattern that remains active in the present.

Rekke is an unusual sleuth even by crime-fiction standards. A psychologist and former concert pianist, he is described as possessing exceptional deductive powers that bring Sherlock Holmes to mind. That sharpness allows him to read the crime in a way others cannot: he concludes that two people kicked Ramirez, one far more brutally than the other, and that the violence was shaped by a deep hatred of women.

That insight pushes the investigation toward a larger theory. Rekke suggests the police may be looking at a serial killer, not a single offender. Similar unsolved cases have surfaced in other countries, and the victims are intellectual women. In each case, the bodies bear strange carved symbols, as though the women were cattle, a detail that intensifies the sense of ritualized brutality and broadens the scope of the inquiry beyond Spain.

The novel also introduces two men, Pompe and Dag, whose conversations about women make them appear to be obvious suspects. Pompe openly identifies himself as a sadist and tries to convince the impressionable Dag that all men are sadists. Their exchanges place misogyny at the center of the book’s menace, while also keeping the question of culpability open as the investigation moves through its false leads and possible connections.

Vargas’s role in the case is complicated by a critical medical emergency that slows her down, though not enough to remove her from the story. When Rekke visits her in the hospital, he notices another patient, a weeping girl, and identifies her as a long-distance runner simply from the sound of her breathing. That kind of uncanny observation is typical of the novel’s approach to detection, and it helps define Rekke as a protagonist whose brilliance lies in perception as much as reasoning.

The result is a police procedural built around classical detective architecture but animated by psychological unease and gendered violence. With its cold-case framework, literary undertow, and increasingly perilous investigation, Lagercrantz’s novel appears set to offer readers a tightly plotted mystery that keeps the focus on what the dead woman left behind and what the living may still be trying to hide.
