The Truth is a play in four acts by Clyde Fitch, first performed in 1906 (some sources say 1907).
Eve Lindon is a 1903 society matron who suspects her husband, Fred, of having an affair with her good friend Becky Warder.
She hires a private detective to follow him around and finds out that Becky and Fred have seen each other almost every day.
The situation is complicated by Becky's view of reality, that she can lie whenever and however she wants.
Becky has told so many lies that her claims that she hasn't been meeting with Fred daily begin to sound suspicious to Tom.
