What happens
Dorothy reveals that she has solved the mystery of the treasure by interpreting the Latin motto 'In robore fortuna' as a reference to an oak tree (rouvre). She explains that the diamonds are hidden in the hollow of an oak. Later, she learns from Raoul that there were two gold medals—one invalid, one valid—and realizes that she inadvertently robbed Raoul of his inheritance. She secretly resolves to restore it. At a family dinner, she is lighthearted and affectionate. The next morning, she leaves a letter declaring that Errington, Webster, Dario, and Raoul are the true heirs and that the fourth diamond is theirs.
