The third Simon & Elizabeth Mystery takes place in Elizabeth's darkest time. Mary I is on the throne, and Elizabeth will quite possibly be put to death for plotting treason. Mary is one of my least favorite people from that time, though I understand how she came to be as she was.
I feel compelled to say here that I dislike the practice of some authors of turning the people of the Tudor Age into what they were not. Some authors go too far to sell books, making a soap opera out of the lives...
