The Arsonists by Max Frisch, adapted by Alistair Beaton. Fires are becoming something of a problem, but Biedermann has it all under control. The great philanthropist, he is happy to meet his civic duty and give shelter to two new houseguests. When they start filling the attic with gasoline drums, he’ll help them wire the fuse. Directed by Malcolm Morrison, this absurdist comedy is part moral fable and part dark farce. Performance times: Thursday & Friday at 6:30; Saturday at 7; Sunday at 2.
