Spring 1908: Brilliant young English doctor Max Liebermann and tenacious Detective Inspector Oskar Rheinhardt are now working as an established crime-solving partnership. Max is now a published author in the field of criminal psychopathy and has finally moved out of his parents’ house into a plush apartment of his own. Oskar’s reputation has been bolstered by his successful investigations with Max, and while he is still at odds with his superior Von Bulow, Oskar’s star is on the rise. But in the grand cafes and opera houses of Vienna, cultures, ideas and crime still flourish.
