Written by John Patrick Shanley, Doubt: A Parable centers on a story of suspicion and morality set in a Catholic school in the 1960s. When a popular priest is accused of misconduct, a determined nun becomes convinced of his guilt, despite having no evidence to support her claim. The play has won numerous awards, including the Pulitzer Prize for Drama in 2005, and has been called a modern classic. The play explores themes of power, authority, and the dangers of certainty in the face of ambiguity. This locally produced work includes a performance by Derdriu Ring, who plays Sister Aloysius, and Christopher Bohan, who plays Father Brendan Flynn, both members of Actor’s Equity Association. Tonight's performance takes place at 7:30 at the Beck Center for the Arts. The play runs through June 25.
