When Conrad fails to return home from a conference one evening, Eleanor's first thought is one of relief. Their marriage has been a sham for over a decade, held together only for their children and by their separate lives in Cambridge. But when she is unable to contact him over the following days, Eleanor begins to worry. Conrad hasn't used his credit card, has left no message; he has just disappeared. As her investigation mounts, secrets from one summer, twenty-five years before, start to reveal themselves, as does Conrad's covert work as a whistleblower, unravelling both of their lives... Conrad and Eleanor is a sensitive, evocative portrait of estrangement, midlife crisis, and how love in a marriage, pushed to its limit, can endure.
