Confused with the end. If anything is answered in the next books, please just let me know. I'd prefer not to be spoiled. 1. Is the book that Matthew left for Sarah one of his annotated books Ysabeau sent him? 2. Why did the silver coffin shot down the chimney and release the blood and mercury? 3. Should I know why the atmosphere changed after Sarah left? Why it smelled like cinnamon, blackthorn, honeysuckle, etc.
