Louise Till, mother of two, has inherited her father’s hardware store after her parents’ unexpected deaths. She begins to cut copies of her customers’ keys for herself, each one a talisman against grief and the terrible guilt she feels at not having realized that her parents were desperately unhappy.

Louise could use the keys, but she doesn’t. Not until her life is overturned, again, when her marriage falls apart. Lou gives in to temptation, letting herself into Euphemia Rosenbaum’s home. What follows is a tale of blackmail, break-ins, an unsolved mystery, and more secrets than Lou ever wanted to know.

Lou must confront not only the lives of her neighbors, but the unspoken truths of her family and the doors within herself for which there are no keys. Told over the course of one long winter, Unlocking is a poignant and penetrating exploration of grief, community, family, and the secrets we keep, even from ourselves.
