NEW YORK (AP) — For decades, Robert Lecker has read, taught and written about Alice Munro, the Nobel laureate from Canada renowned for her short stories. A professor of English at McGill University in Montreal, and author of numerous critical studies of Canadian fiction, he has thought of Munro as the “jewel” in the crown of her country's literature and source of some of the richest material for classroom discussion. But since learning that Munro declined to leave her husband after he had sexually assaulted and harassed her daughter, Lecker now wonders how to teach her work, or if he should even try.
