The story mostly takes place on a train. Lemony works with his partners. Even though his partners are adults, they treat him like an adult as well because he is a good detective.
One night Lemony was left home with his chaperone. She told Lemony that he had an early bedtime and then she left him alone at home. She wasn’t supposed to do that so Lemony waited a few minutes then got out of bed and watched her get onto a train. The next thing you know a librarian is murdered, the chaperone is blamed and Lemony is on a quest to prove she is innocent because the police were not doing anything. Lots of action unfolds as Lemony unravels the clues and works with his partners to solve the murder.
The story was exciting and funny at times. It is 304 pages. It isn’t a scary book, but it has a little bit of adventure in it. I think this book is good for kids 4th grade and up because that’s when they’d have the right understanding of the vocabulary.
This book is part of a 4 book series. Although this is the final book, I look forward to going back and reading the other three, starting with the first one “Who Could That Be at This Hour?”.
