Antiques dealer Richard Steinmann was beaten to death in his shop. Hofer and Bach investigate. Employee Monika Lerch reports he rowed with son Stefan, who points in turn at step-mother Diana, allegedly a gold-digger, who has a secret visitor. Monika Lerch recently resigned. Meanwhile Bach lets Stockl talk him into returning the favor of hospitality to hopelessly picky forensic pathologist Sandra Mai by inviting her to his home while her is under water damage repair.
