Silvia Severová

A romantic story of a young nobleman who sees a beautiful girl at the carnival who seems familiar to him. He feels that he saw her in an old castle, where only the old countess and sister live. It is precisely in their salon in the city that she meets the girl again and learns her history

Jealous of her vapidly "good" sister's popularity, poisonous Viktoria doses pretty Klara's tea with a slow-acting fatal substance. As the latter grows hysterically weak, the former finds success increasingly compromised by guilt, blackmail, and the pesky need to kill others lest she be exposed.
