Widowers' Houses

This is one of three plays Shaw published as Plays Unpleasant in 1898; they were termed "unpleasant" because they were intended, not to entertain their audiences—as traditional Victorian theatre was expected to—but to raise awareness of social problems and to censure exploitation of the laboring class by the unproductive rich. In this play, Dr. Harry Trench becomes disillusioned when he discovers how his fiancee's father, Mr. Sartorius, makes his money. However, it is soon revealed that Trench's own income is far from untainted. (Summary by wildemoose and Wikipedia)
