This is a fun cozy mystery with a great location and a delightful amateur sleuth. Opal Laplume’s sheltered life in 1930’s London is turned upside down when her Mother sends her to Paris to help a distant relative. When a murder happens and the police don’t seem interested in finding the true killer, Opal decides to solve the case.  
Opal is an interesting combination of brilliance and innocence, plus she has a dog named Napoleon who steals every scene he’s in.

The narrator does a nice job handling both the English and French accents.
