Later in the evening, Betteredge reminds Cuff that the Indians will be released from jail tomorrow. Cuff resolves to question them in the morning, with Murthwaite's help.
Betteredge runs into Rosanna, looking pained, in the hall. She is running from Franklin, who reports that Rosanna had come into the billiard room wishing to speak to him but had left in a frenzy because he would not look at her. Franklin meant no offense to her but believes she was about to confess the theft to him. Betteredge goes to check on Rosanna's hurt feelings, but she declines visitors.
Betteredge finds Cuff sleeping on some chairs outside Rachel's room. Cuff is prepared to discover any overnight private communication between Rosanna and Rachel.
Cuff discovers no communication between Rosanna and Rachel overnight. In the morning, Cuff approaches Franklin and Betteredge walking outside. Franklin is still cold to Cuff because of Cuff's suspicions of Rachel. Cuff asks Franklin what Rosanna said to him the night before, but before Franklin can answer, Rosanna herself appears ahead of them with Penelope behind her. Cuff notices her and begins speaking louder about the conversation between Rosanna and Franklin. Franklin, pretending not to notice Rosanna, reassures Cuff, "I take no interest whatever in Rosanna Spearman." Rosanna overhears and lets Penelope take her back in the house. Franklin regrets his harsh words but explains to Betteredge that he used them to protect both himself and Rosanna from Cuff's inquiries. Franklin asks Betteredge to make it up to Rosanna.
Cuff goes to Frizinghall. Penelope asks Betteredge to visit Rosanna and cheer her. Betteredge tries to speak with Rosanna, but she acts as though entranced. Betteredge urges her to "make a clean breast of it!" but Rosanna insists she will speak only to Franklin and returns to her work. Betteredge resolves to speak with Lady Verinder of Rosanna's troubled state, but the Lady is shut up in a room with Rachel. Betteredge hears Cuff return from Frizinghall.
In Chapter XV, Cuff's ability to sympathize with others becomes a detecting tactic, as he solicits information about Rosanna from the Yollands by pretending to be sympathetic and manipulating Mrs. Yolland's response. The information he gets from Mrs. Yolland—information about Rosanna's purchases of a tin case and chains—is information about object clues. Object clues now make up the basis of any detection story. Rather than the suspicious behavior of individuals, objects usually provide the answers to the mystery. This tactic of organization owes much to publicized court cases, in which objects are entered as incriminating evidence.
