With Twelfth Night, Writers Theatre takes one of Shakespeare’s most conflicted comedies and instills it with warmth, wit and emotional clarity. The story launches with a shipwreck and closes snowfall. In between, there are lovers, liars and fools who make the language sing, even when it’s weeping. Performances run through Dec. 16 at Writers Theatre, 325 Tudor Court, Glencoe. Tickets are $35-$80; visit WritersTheatre.org.
