Marquis Henri brings his new employees to the castle at night and reveals his true identity. He tries to reassure them about the ghosts. He has resolved to restore his immense castle, which has been badly neglected in his absence. He discovers a letter in the castle stating that the infant Vicomtesse de Lucenay was at one time in danger and so was entrusted to Gaspard to be brought up under a false name. Everyone thinks this must refer to Serpolette. Henri also finds himself becoming attracted to Germaine. She tells him the story about how Grenicheux saved her, and how she feels obliged to marry him. Henri realises that Germaine is the girl that he himself had rescued and that Grenicheux's claims to have done so are false.
