Jailed for stealing from the store where she worked, the honest shop clerk Mary Turner (Elisabeth Preston) takes vengeance against her employer by marrying his son. This Metropolitan Playhouse revival of Bayard Veiller's 1912 play reminds us that income inequality, living wages and an arbitrary criminal justice system have long been fodder for popular entertainment. But as intriguing as some elements are, the play is less a revenge thriller than a creaking melodrama (2:30).
