This is a really good book. We have all the regular characters in this story along with Peabody's brother making an appearance. 
 In terms of the story line it was a complex and well developed plot. (view spoiler)[I love how all the 3 mysteries came together. I knew they would be connected but couldn't figure out how. (hide spoiler)] 
 And finally what I had been waiting for !!! (view spoiler)[ Peabody and MacNab together (hide spoiler)] 
 I do wish a little more was written once the day was saved though.
