Guest host Jane Curtin presents three stories about unexpected encounters at night. In Steven Millhauser’s “Claire de Lune,” a teenage boy with insomnia wanders into an all-girl pickup game. It’s read by James Naughton. Comic Wyatt Cenac reads Sherman Alexie’s “Night People” in which a man who can’t sleep visits an all-night manicure parlor. And a young man struggles to protect a loving but alcoholic father in “Luck,” by Richard Bausch, read by Campbell Scott.
