Julian Barnes’ memoir of grief for the death of his wife Pat Kavanagh in 2008 after a thirty-year relationship, must be one of the most moving tributes ever paid to a loved one, but also the most oblique. So let’s start with something simple, a photograph. Look up the title in the Daily Mail of London, partly for the marvelously-titled review “Lifted by Love, Grounded by Grief” by Craig Brown, but mostly for the photograph that accompanies it. Julian is seated. Pat stands behind him, her arms around his shoulders, her chin resting on the crown of his head. Her love is obvious, she whom Barnes refers to as “The heart of my life; the life of my heart.” But equally striking is the unusual vertical composition. Pat, who on the ground was a small woman beside the gangling Barnes, here appears above him, like a guardian angel reaching down.
