A wave of apparently random homicides is sweeping through their idyllic seaside town of Helsingborg. The murders have no pattern, no order, no reason.
The perpetrator is immune to psychological profiling; forensically untraceable; utterly invulnerable to modern police techniques. The body count is growing. But lead investigator Fabian Risk is distracted by his mission to expose a corrupt colleague, and his boss Astrid is spiralling back into addiction.
As the hunt for the solution becomes ever more desperate, their tight-knit team begins to unravel.
Motive X is both an explosive, multilayered thriller and a fearless exploration of the darkest side of human nature.
