Murder on the Mirrored Lake

What book are you reading right now?

It is a murder mystery set in England in the 1800s. I have just started reading this. Chapter one already has some lady murdered at a lake.

It is kind of slow. After the lady is murdered, it flashes to lead to why she was. There are times I get bored if the story has a flash back and moves forward so I can figure out the killer. Hopefully this won’t. Somehow the characters are connected. Mysteries are the genre I like best.
