⚠️ Spoiler Warning: This guide contains detailed spoilers for the entire novel. Proceed only if you've finished reading or are comfortable knowing the plot.
Summary
Late the next afternoon, Claire finds Brianna alone in the surgery of the New House. She explains that Denzell Hunter, a Quaker doctor and Rachel’s brother, has been captured by the British and is held at Stony Point. Claire wants Brianna to write to Lord John Grey, whose brother the Duke of Pardloe is Denny’s father-in-law, to alert him. Brianna questions why Claire does not write herself, and Claire reluctantly admits that Jamie had a falling-out with the Greys. She then confesses she married Lord John when Jamie was thought dead and slept with him. The shock of this revelation triggers a frightening heart episode in Brianna—atrial fibrillation, a condition she has had since traveling through the stones from Ocracoke. Claire diagnoses it as paroxysmal atrial fibrillation, explains the risks and limited treatments, and reassures her daughter while preparing willow-bark tea as a blood thinner.

Why This Chapter Matters
This chapter is pivotal because it reveals a long-held secret about Claire’s marriage to Lord John Grey—a fact that has emotional and relational consequences for the entire family. It also introduces a serious medical issue for Brianna that will likely affect future plot developments. The window into Brianna’s physical and emotional state adds a layer of vulnerability to a character usually seen as strong and capable. Furthermore, the chapter advances the rescue of Denzell Hunter through Lord John’s family connections, tying together multiple storylines.
Study Questions
-
Why does Claire choose Brianna to write to Lord John rather than writing herself?
Claire wants to avoid provoking Jamie’s anger over her past relationship with Lord John. She believes Brianna can write without raising suspicion because Jamie would not expect Claire to have shared the story of the falling-out. -
What does Brianna’s atrial fibrillation reveal about her emotional and physical state?
The condition first struck after her traumatic journey through the stones at Ocracoke with Mandy. It reflects the lingering stress of time travel, motherhood, and the fear of death. Her reluctance to tell anyone shows her desire to appear strong and not burden her family. -
How does Claire’s medical response reflect the limitations of 18th-century medicine?
Claire can diagnose atrial fibrillation but cannot perform cardioversion or regulate digitalis doses. She must rely on willow-bark tea (a precursor to aspirin) to thin the blood and teach vagal maneuvers to manage acute episodes—emphasizing the gap between her 20th-century knowledge and available resources.
