This review is primarily for Spanish teachers to help them determine if this book would be a good fit for their classrooms. It's rated a Level 3 book. The story lasts only 18 pages of the book. After the story are great glossaries in English, Spanish, French, and German giving terrific cultural information about the places and customs, such as nicknames, mentioned in the book. There are three black and white photos with drawings of the main characters superimposed on them.
Pepe Rey is a detective in Madrid. He's off to take a case in Barcelona. As he's leaving he hears a song that reminds him of his old girlfriend from 1969 when he was 24. (The book was written in 1987.) Who should he meet on the flight but Lola, the old girlfriend? He wants to catch up but she doesn't seem as interested. What business does Lola have in Barcelona?
I hadn't read any Pepe Rey books before this one so I don't know if all the endings are like the ending in this book. Perhaps there is a sequel that explains what happened next.
There are a few potential issues with the book. Pepe drinks beer and wine. If the students don't pay attention to the publication date, they will probably turn out the story with Pepe being 69 today in 2014. When written, the character is only 42. It mentions that the Barrio Chino has strip-tease clothing stores on the same street as bridal shops. (No one goes to a strip-tease store.)
Overall, given the enthusiastic reviews for other books in the series, I hope this book was just abnormal for the series.
