Gay marriage may be gaining momentum in the 21st century, but this famously provocative Lillian Hellman period piece from the previous century (1934) exploits the common mistrust and disapproval of a same-sex relationship — a “reality” instigated by a malicious lie told by a young teenager at a girls’ boarding school. The play, supposedly written with the assistance of Dashiell Hammett, was inspired by a true story involving two Scottish teachers. It remains relevant even in our more open-minded times, mainly because the chief theme concerns the way lies and gossip can have a devastating effect on human lives. Street Theatre Company founder Cathy Street directs a cast of 14 that includes Terra Buschmann, Jaime Janiszewski, John Mauldin, Deanna Glasser and Haley Covington as 13-year-old Mary Tilford. The live musical underscoring is by Rollie Mains.
