Arsène Lupin : The Secret Tomb

Dorothy, a ropedancer and palmist, arrives at the Château de Roborey with her travelling circus, made up of motley crew of war orphans and notices strange excavations at the grounds.

As a long day ends, Dorothy grows worried about her friend Saint-Quentin a young boy with a passion for adventure and a penchant for getting into trouble. Dorothy sets out to hunt for Quentin.

Remembering the castle they had recently discovered, and recalling that it had fascinated Saint-Quentin who had wanted to break in, Dorothy makes her way to a rocky outcrop surrounding the rampart, where she discovers a lurking figure. She quickly hides and observes as he furtively opens up a secret passage into a hidden lair. Just then, she sees Saint-Quentin climb out of a castle window, which the man also sees and aims a rifle at Saint-Quentin, forcing Dorothy to rush out and save Saint-Quentin's life, and is now plunged headlong into mystery and adventure.
