Robin Stevens' First Class Murder
The third book in Stevens' Wells and Wong series (about two fourteen year olds solving mysteries in the 1930s) is a straight up homage to Murder on the Orient Express, as Hazel's father comes from Hong Kong to take the girls on a tour of Europe on the famous train--and of course there's a murder. BUT there are also several other amateur sleuths on board getting in their way! And it's hilarious. I really appreciate Stevens' take on the racism of the day (and how Hazel reacts to it), as well as the period-appropriate anti-Semitism. And the friendship between the girls is very well-done. These books are just DELIGHTFUL. A-.
