…Gone Girl is Ms. Flynn's dazzling breakthrough. It is wily, mercurial, subtly layered and populated by characters so well imagined that they're hard to part with—even if, as in Amy's case, they are already departed. And if you have any doubts about whether Ms. Flynn measures up to Patricia Highsmith's level of discreet malice, go back and look at the small details. Whatever you raced past on a first reading will look completely different the second time around.
