He strikes at random. His motive unknown. No one is safe... Helsingborg police must solve the unsolveable. A wave of apparently random homicides is sweeping through their idyllic seaside town. 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 becoming ever more desperate, their tight-knit team begins to unravel... Motive X is both an explosive, multi-layered thriller and a fearless exploration of the darkest side of human nature. To enter Stefan Ahnhem's world, with its interwoven plotlines and sprawling cast of characters, is to put yourself in the hands of a master storyteller. The story continues in X Ways to Die, available May 2020.
