I am a French teacher, and have used this excellent curriculum to teach French to high school students. It is a fun romp through France, learning famous landmarks, French culture, geography, clothing, newspapers & signs, zoo animals, and much, much more. The mystery aspect creates intrigue, keeping the students motivated to solve the mystery by finding all the clues. The verbal boasting of "Secret Agent X24", and his posturing as an expert, are brilliant devices for keeping students' interest. The many photos, the vocabulary glossary, the study questions, and other activities at the end of the book makes is very easy for students to use the curriculum. Highly recommended!
