Japp soon arrests Marsh, based on this letter. Marsh denies hiring Adams or killing his uncle but states that he and his cousin Geraldine went to Regent Gates on the night of the murder, where he spotted Martin entering the house while she was getting something for him. Poirot later receives the original letter in the post and notes some oddities with it. Hastings attends a luncheon party along with Wilkinson and Ross, in which the guests talk about Paris of Troy. Wilkinson presumes they are talking of the French capital. Ross, puzzled by this, confides his concerns to Hastings. He later telephones Poirot but is fatally stabbed before he can explain in detail. Seeking a theory, Poirot overhears a chance remark from a crowd leaving a theatre, which leads him to talk with Wilkinson's maid Ellis.
