Oskar und das Geheimnis des Klosters

Betrayal Behind Cloister Walls. Finally vacation! But what are Oskar's parents planning? Archaeological excavations at Maulbronn Monastery. Oskar finds it really boring – and promptly disappears into the Middle Ages to join his friend Albrecht Dürer. But even here, he ends up in a monastery – and in an exciting mystery involving a valuable icon, false pilgrims, and betrayal behind cloister walls. 'Oskar and the Secret of the Monastery' is the third time travel adventure that Oskar experiences in the Middle Ages, following the first two volumes 'Oskar and the Secret of the Disappeared Children' and 'Oskar and the Secret of the Children's Gang.'.
