Mix of Groundhog Day, Quantum Leap, Clue, and Downton Abbey

What happens when you mix an Agatha Christie-esque mystery with a Groundhog Day loop, a dash of Quantum Leap, Clue, and Downton Abbey? That is the appropriate question for this book. I found this book very clever and I really enjoyed the mystery though it required me paying attention as it can get confusing. The main character steps into so many others and re lives the day from their perspective. Paying attention to the details is imperative and he learns something new each time. It was also interesting to see how the different bodies/personalities affected the story and there were twists I didn’t see coming. I did not want to put it down and I quickly raced to the end. I am still thinking about the reveal days and months later.
