Acoustic forensics, an opaque profiler, and a kidnapped baby: the thrilling continuation of the No. 1 Spiegel bestseller "Auris" by thriller authors Vincent Kliesch and Sebastian Fitzek! "Help, my baby is gone! There’s only blood here..." After brief sounds of a struggle, the panicked emergency call from a mother to 112 suddenly cuts off. If anyone can deduce the whereabouts of the woman from this audio fragment, it’s forensic phonetician Matthias Hegel – who some still believe to be a murderer. True-crime podcaster Jula Ansorge has managed to clear Hegel of the suspicion of murdering his wife, but in doing so, she has come dangerously close to the dark side of the brilliant profiler. Now, when Hegel wants to rely on her investigative skills again in the case of the kidnapped baby, Jula initially refuses. But can she really leave the baby and its mother to their fate? And what about the information regarding her presumed dead brother Moritz that Hegel claims he can obtain for her? In the second installment of the thriller series, bestselling authors Vincent Kliesch and Sebastian Fitzek pull out all the stops once again: nothing is as it seems at first glance, and no one remains as innocent as they would like to be. Fast-paced suspense for fans of extraordinary thrillers with more than one unexpected twist!.
