One morning, Sebastian Pichler finds his 39-year-old wife, the renowned pianist Ruth Baumgartner, dead in her bed in their shared apartment in Winterthur. Everything points to natural causes, but the exact cause of death is unknown. However, a tenacious investigating magistrate and a suspicious, soon-to-be-retired detective—a seasoned veteran—don't give up. Then, an observant pathologist discovers strange, minute changes in the deceased woman's heart. But where did they come from? All the usual drugs are ruled out. The investigating magistrate makes one last attempt and has the deceased woman's stomach contents tested for arsenic—a poison no one had considered. This proves to be a bullseye. But now new questions arise: Did Ruth Baumgartner commit suicide with arsenic? Was she poisoned? Who had a motive? There's a husband with a mistress twenty years his junior and a life insurance policy worth a quarter of a million Swiss francs. But there's also a married lover of the deceased and an extremely jealous rival. A gripping true crime case, authentic and full of unexpected twists. New product
