Intrigue is a comprehensive and flexible intermediate-level French textbook that develops the four basic communicative skills: reading, writing, speaking, and listening. Its proficiency-oriented methodology focuses on communication, linguistic functions, and interactive exchanges. This innovative mystery-story textbook arouses student curiosity and encourages students to participate actively in understanding the story and related authentic documents, to discuss the content of chapter readings, to write about their opinions and reactions, and even to complete grammar review activities—all of which advance the plot and offer clues to solving the mystery. By offering continuity between readings, student listening recordings, classroom activities, and homework exercises, Intrigue draws students into using the French language in meaningful situations and into learning about the cultures of the French-speaking world.
