Lynn Redgrave returns to Broadway as "Mrs. Culver," with Kate Burton as "Constance Middleton" in the Roundabout Theatre Company's new Broadway production of W. Somerset Maugham The Constant Wife. Mark Brokaw directs. The Constant Wife is a social comedy of marital maneuvers in 1920s upper-class London. Constance Middleton discovers that her husband is having an affair with her best friend. Rather than humiliating herself and others, she denies the affair, defends the two, and sets about turning bad luck, unfaithful friends, local gossip and a broken heart to her own advantage.
