"We are, uh, on a sort of...train?" he said carefully. "It is a...très étrange...very strange? thing. I think, whoever you are calling for, they are not here. But nobody will harm you."
He bowed formally.
"You are safe here, Mademoiselle. That at least I can tell you. My name is Marius Pontmercy. What are you called?"
