Jacob Luria is asked by his good friend, Mary Daly, to spy on her husband, whom she has long suspected of infidelity. Obsessed by his love for her, by his hope that her marriage will finally fail, Luria is troubled in this assignment by the all-but-certain prospect of his own abasement and pain. Ghost Story is a novel about truth and deception, hope and despair, and the strange, often inexorable, ways we are haunted by those we love.
