Meanwhile, Sir Henry argues with Barrymore over the chase of his brother-in-law, Selden. Watson and Henry worry that the man is a public danger. Nonetheless, Barrymore assures them that Selden is just biding his time until a ship arrives for South America, and that he will not commit any more crimes. Barrymore's betters agree not to tell the police, and Barrymore thanks them by offering another clue. Apparently, Sir Charles went to the gate on the night he died to meet a woman, and Barrymore tells of his wife's discovery of a charred letter, signed L.L., requesting the late-night meeting.
