Joyce Wadler: “I was working as a reporter at People magazine, back in 1988, when I saw the Broadway show the case inspired, David Henry Hwang’s wonderful M. Butterfly, and it raised many questions: How could a guy make love to another guy for months and not know? Where had the kid come from? How could I get to Paris, where the two men were now living after spending time in prison, on somebody else’s dime?”
