In the dynamic and dangerous Vienna of 1903, a brilliant psychoanalyst and a brave detective battle to catch criminals who commit the most clever and brutal crimes.
Detective Inspector Oskar Reinhardt finds that young women are being slain in an unnerving-and ingenious-manner, with a small, almost undetectable, hat pin. For Dr. Max Liebermann, the killer is unique in the annals of psychopathology, one who murders in the midst of consensual love. Is the culprit a patient, one who swears he has a double, a shadow figure that is far more forward (in fact, indecent) with women? As danger mounts, Liebermann must find the answer while struggling with his own forbidden desire for a female patient.
