In the two novellas that make up The Equations of Love, Ethel Wilson describes ordinary people in perilous circumstances with extraordinary insight and compassion. “Tuesday and Wednesday” reconstructs the events of two days in the life of Mort and Myrtle Johnson, whose uninspired marriage is strangely transformed by the tragic intervention of fate. “Lilly’s Story” is the study of a woman who, protecting her daughter, invents a new identity for herself, only to live as a fugitive from her own happiness. Fist published in 1952, these intuitive and richly ironic stories reveal the unspoken longings and surprising motives that balance the equations of love.
