I got this book thanks to Penguins Early Reader Program. 
 All right, so lets start off with what I liked. I liked Charlotte and her sister. I loved the idea of their relationship being so close, probably because I never had a sister, but if I had, I'd want the idea of it being like theirs. 
 I loved loved loved Mrs. Watson. I don't think there is a better character than hers. She's smart, her head and her heart are in the right place. I love the picture she paints. 
 What I disliked... I disliked that some things Charlotte failed to notice while other things she magically understood out of no where. I disliked that she could easily explain her observations, but it was only as a convenience for the story to move along. Same with her failing to notice things, it was just a mechanism to carry the story line along. 
 I hated that there were so many characters. Obviously it's to set up a series of another book, but by the end I really didn't care why two of three victims died. I'm not even sure I quite understand why they died either.. was it murder or suicide. 
 I hated Mr. Sackville's crime. It was as if the author said to herself... I need people to hate him, what the worse thing I can think of... it just kind of comes out of no where. 
 I felt Charlotte's need to prove her mind was contrived and silly. I couldn't help but roll my eyes every time it was mentioned that shed go off into the room and pretend to speak with her brother Sherlock. Felt like such a big production, too over the top. 
 However, it wasn't really to the end that I started to wish for it to be over. The characters and the setup are all pretty good and when the next book comes out I will probably read it.
