Into the abyss of the human soulA body has been found in a quarry pond close to Munich. Superintendent Katja Sand and her assistant Rudi Dorfmüller head the investigation. The victim was a petty officer on a naval corvette – and couldn’t swim. Was it suicide? Then another corpse is discovered, this time in a refrigerator at a recycling facility. The detectives soon learn that both men had been clients of well-known psychoanalyst Dr. Alexander Hanning, who was helping them cope with personal traumas. The parallels between the two causes of death are also striking: In both instances, a severely traumatized man died under strange circumstances which were reminiscent of the catalyst event that had caused his personal trauma. In order to figure out the role Dr. Hanning might have played in these crimes, Katja becomes a patient at his practice. And finds herself in mortal danger.
