Ver Cuevana3. The Ghost Sonata relates the adventures of a young student, who idealizes the lives of the inhabitants of a stylish apartment building in Stockholm. He makes the acquaintance of the mysterious Jacob Hummel, who helps him to find his way into the apartment, only to find that it is a nest of betrayal and sickness. The world, the student learns, is hell and human beings must suffer to achieve salvation. The play centers on a family of strangers who meet for the sake of meeting. They exchange no dialogue, nor gestures, they simply sit and bask in their own misfortune.
