Mrs. Hess was one of Johan Liebert's accomplices, though her exact relationship to him remains murky throughout the story.
She first caught attention attending counseling sessions with Dr. Julius Reichwein, complaining about marital problems. When Reichwein suggested bringing her husband in for a joint session, she agreed—but the man who showed up was actually Roberto, sent by Johan to assassinate Reichwein for digging into Detective Richard Braun's death. Kenzo Tenma happened to intervene just in time, saving the doctor's life.
Later, Mrs. Hess appeared at a book donation ceremony at the University of Munich library hosted by businessman Hans Georg Schuwald. Johan was there too, and following his instructions, she poured gasoline between the bookshelves and set the place on fire while mimicking his movements. It was a clear sign of her willing participation in his plans.
The nature of her relationship with Roberto is genuinely unclear. She claimed to be married to him, but given his habit of sleeping around with women like "Sausage," Blue Sophie, and Eva Heinemann, either those claims were false or she was okay with an open arrangement. What ultimately happened to her is never revealed.
