1829. A mansion on the Cornish coast. The maid, Sarah Leeson, witnesses the final minutes of her mistress’s life—Lady Treverton. The mistress dictates a note to the maid and makes her promise to deliver the message to her husband. But it seems Sarah has no intention of giving the note to her master, because the very next morning she vanishes without a trace, taking the secret with her.
What ties these two together, and why was leaving in an “English way” easier than fulfilling the late lady’s last wish?
