I loved this until I got to the last page. WTF, Maureen Johnson? Why is this “to be continued”? This was a super exciting classic mystery with nods to Agatha Christie and Sherlock Holmes, with flashbacks to a crime in the 1930s meshed with a present day situation in the same location, which happens to be an eccentric and elite boarding school for brilliant teens. I mean, it’s great right? Not unlike Johnson’s Jack the Ripper boarding school awesome story. But things were rolling right along with a good level of excitement and tension, everything about to be solved when… the end. Seriously, this book could have just used 20 more pages to finish everything up and I would have given it 5 stars. Instead it’s being strung out into a trilogy, which is ridiculous. As you can tell I became quite enraged at the end.
