Because every murder claims more than one victim. Josef Wilfling has apprehended one of Germany's most dangerous serial killers and solved other spectacular cases. However, the power of the perpetrators extends beyond their crimes, as the legendary homicide detective demonstrates in his new book. Every murder brings complex consequences: the lifelong suffering of the victims' families, the stigmatization of the perpetrator's relatives—and often, the investigators themselves feel the repercussions of a murder firsthand. Wilfling candidly describes situations where he too reached his limits, such as in the case of a sadistic rapist and murderer: the awareness of the victims' vulnerability; the anger that overcomes professional detachment; the frustration when evidence is insufficient in court.
