Un grupo industrial farmacéutico ha encargado al detective privado Gerhard Selb, de 68 años, que busque a un pirata informático que pone en jaque el sistema informático de la empresa que dirige su cuñado. A lo largo de la resolución del caso deberá enfrentarse a su propio pasado como joven y resuelto fiscal nazi, y encontrar una solución particular para esclarecer dos asesinatos cuya herramienta ingenua había sido.

Sixty-eight years old; a smoker of Sweet Aftons, a dedicated drinker of Aviateur cocktails, and the owner of a charismatic cat named Turbo, Gerhard Self is an unconventional private detective. When Self is summoned by his long-time friend and rival Korten to investigate several incidents of computer-hacking at a chemicals company, he finds himself dealing with an unfamiliar kind of crime that throws up many challenges. But in his search for the hacker, Self stumbles upon something far more sinister. His investigation eventually unearths dark secrets that have been hidden for decades, and forces Self to confront his own demons.
