I'm re-reading bees and I'm in chapter 119.
The Sachem just told Claire that Frank's ghost often follows her and Jamie. Claire goes to Jamie's study and picks up the book, contemplating about his motives in relation to his letter to Brianna.
I remember Jamie told Ian about his possibly imminent death in the Battle of Kings Mountain, but I'm confused: Did Jamie told Claire by this point?
I don't know if it is the show that confused me and it happened differently in the book, I accidently skipped this section of the book or just can't remember when it happened.
Thanks in advance!
