Yes, Louis Edmonds was good. And Angelique was mean. She's quite capable of making Daniel forget his whole life without threatening him, but she had to have her fun. Give Angelique a nice way to do something and a malicious way, and she'll always choose the malicious way.
I had forgotten that it was at Widows Hill that Daniel killed Harriet. Shoved her off, apparently. What were they doing up there in the first place? I'd speculate that there was another man involved, but that's not the impression I get from Daniel.
We got the story of what happened to Judah Zachery in 1692. It's sort of rickety. I'm bothered by the statement that witch trials were taking place all through New England: in 1692 they were taking place only in the Salem area, I believe. And Barnabas speculates that the deaths in the Collins family related to Judah Zachery stopped because the Head was taken out of the US, but that didn't happen until the early 1800s. Barnabas says he heard a lot about the trial when he was a boy, which would have been 80 or 90 years after it happened. Josbua and Naomi started out in 1795 as pooh-poohing any talk of witches, so I guess it must have been Abigail talking. I'll bet she was terrifically envious of Amadeus Collins for experiencing all that excitement.
Doctor or no, you would not get me to go look at a headless body without bearing arms, lots of ammo and plenty of backup.
Or at least a good stiff sedative to dispense.
