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 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. PRAISE FOR STEFAN AHNHEM: "Atmospheric and complicated ... with great cop characters and some imaginatively grisly perps. " SUNDAY TIMES
