I had to admire the way this dual timeline story unfolded. In the present, we have murders occuring and the killer naming it "art". A bit creepy in that it started with wooden figures and then jumping to actual people. 

Then I was really interested in the 1666 storyline. I've heard of the fire that destroyed London but didn't know much about the history of a St. Paul's church and an architect named Wren. Loved how Margaret, one of the Queen's ladies, was interested in science and the way she investigated things that happen after the fire.

I really liked how the two times were connected and I was very engaged in each one.
