Do you know this gentleman burglar, hero of popular literature? Well his creator was born in Rouen and made Normandy his playground. He is Maurice Leblanc. You can see his birthplace, his high school, the square where he made his most beautiful literary encounters and, of course, immerse yourself in the sumptuous setting of Jumièges Abbey that he used for The Countess of Cagliostro. With the writer’s uncle living in the house next door to the abbey, the young author spent many vacations there and let his imagination wander in its most bewitching landscapes. A visit-mystery and a visit-magic permits, with facetiousness, to discover the world of Leblanc and his hero.
