The Ghost Sonata (Spöksonaten) is a play in three acts by Swedish playwright August Strindberg. Written in 1907, it was first produced at Strindberg's Intimate Theatre in Stockholm on 21 January 1908... The Ghost Sonata is a key text in the development of modernist drama and a vivid example of a chamber play. In it, Strindberg creates a world in which ghosts walk in bright daylight, a beautiful woman is transformed into a mummy and lives in the closet, and the household cook sucks all the nourishment out of the food before she serves it to her masters. The play 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. (Summary by Wikipedia)
