If you’re looking for certainties, you’re at the wrong address… here there are only mysteries.
If you find yourself in Amsterdam strolling along the canals, you probably won’t notice Casa Intrigue, a house that looks completely ordinary—except for a lemon-yellow mailbox. Here lives a family of spies, ready to receive mysterious missions from Aunt Edna.
In the third book of the series (A blood-red letter), an unusual-coloured envelope arrives at the Intrigue home. It comes from Mr. Riddles, a refined man who loves puzzles and invites the Intrigue family to a villa in Provence. A group of spies and the winner of a strange prize trip await them. What are they all doing there? And the mystery immediately thickens.
- A series with the perfect mix of humor, adventure, and intrigue!
- A bright and sparkling writing style that can capture even the most reluctant reader.
