She tried hard to be a good wife, and to please her very good husband, but a full accounting of the success of her efforts must include the e-mails that she and Richard began to exchange within days of his departure, and the permission she somehow gave him, a few weeks after that, to get on a plane to Minneapolis and go up to Nameless Lake with her while Walter was hosting another V.I.P. trip in the Boundary Waters.
