Mrs. Hess was an accomplice of Johan Liebert. She first appeared at counseling sessions with Dr. Julius Reichwein, generally griping about her relationship troubles with her husband. As such, Reichwein suggested that she should have her husband come in for a counseling session, which she readily agreed to. However, her "husband" turned out to be no less than Roberto, who was there to personally kill Dr. Reichwein for his investigations into the circumstances behind the death of his former patient and later friend, Detective Richard Braun. Reichwein was only saved by the narrow intervention of his one-time student, Dr. Kenzo Tenma. Later, Mrs. Hess appeared at a book donation ceremony at the University of Munich library on the part of the business tycoon Hans Georg Schuwald, which his secretary Johan Liebert was also attending. On Johan's instructions, she covertly poured gasoline among the bookshelves, lit a match, and set the building ablaze, while mimicking his motions. This confirmed her complicity in his machinations. Whether Mrs. Hess is actually married to Roberto or not is left unspecified, though it is likely that either her claims as to their marriage were false or she is in an open relationship with him, on account of his frequent bouts of sexual activity with other women (eg. "Sausage", Blue Sophie, Eva Heinemann). Her ultimate fate is left unseen. (Source: Monster Wiki)
