That same evening, Gregory at last discovers the jewels hidden in plain sight, disguised as costume jewelry. He returns home to find that Paula has apparently been visited by another man. Though he knows that he has been discovered, he throws Paula into confusion again, telling her that everything is in her imagination. However, Cameron suddenly appears and confronts Gregory, chasing him to the attic and finally arresting him. Paula follows them and, finally convinced of her own sanity, indulges in a bit of revenge. Alone with him now bound to a chair, he tries to convince her to cut him free so that he can escape. She taunts Gregory, musing that the knife in her hand might not be real, before calling in Cameron to take him away.
