Maria Weston wants to be friends with me.

Maybe that had been the problem all along: Maria Weston had wanted to be friends with me, but I let her down.

She''s been hovering at the edge of my consciousness for all of my adult life, although I''ve been good at keeping her out, just a blurred shadow in the corner of my eye, almost but not quite out of sight.

Maria Weston wants to be friends.

But Maria Weston has been dead for more than twenty-five years.
