Miss Emily "Fido" Faithfull is a "woman of business" and a spinster pioneer in the British women's movement, independent of mind but naively trusting of heart. Distracted from her cause by the sudden return of her once-dear friend, the unhappily wed Helen Codrington, Fido is swept up in the intimate details of Helen's failing marriage and obsessive affair with a young army officer. What begins as a loyal effort to help a friend explodes into a courtroom drama that rivals the Clinton affair - complete with stained clothing, accusations of adultery, counterclaims of rape, and a mysterious letter that could destroy more than one life.

Based on a scandalous divorce case that gripped England in 1864, The Sealed Letter is a riveting, provocative drama of friends, lovers, and divorce, Victorian style.
