Her former lover, Zac North, is also a war photographer who becomes “a dead man walking’’ following his experiences in Afghanistan. Somewhat reluctantly, Serena allows herself to be persuaded to help him back to recovering physical and mental health. Working together on her father’s life story and remarkable legacy of photographs, they become lovers again. Then one of those photographs, hitherto unseen, becomes the title’s “secret of the past’’ and a major challenge to Serena’s childhood memories.
