III: A Lady in the Case
Thorndyke instructs Jervis in the proper approach to fingerprint evidence, emphasizing that a fingerprint is merely a fact to be weighed, not a magical proof.

As they prepare to visit Scotland Yard, Miss Juliet Gibson arrives urgently.

Thorndyke questions her about her relationships with Reuben and Walter; she reveals Walter has proposed but she refused, and she speaks highly of Reuben's character. After she leaves, Thorndyke and Jervis discuss the psychological problem of her relations with the two men and note that her praise of Reuben seemed tempered by something she heard from a third party.

Jervis shares this information with Thorndyke, who listens attentively but seems unmoved, leading Jervis to suspect Thorndyke already knows or has another explanation. Polton enters with a set of twenty-four boxwood pieces, and Thorndyke playfully critiques Jervis's use of the word 'guess,' demonstrating deductive reasoning by identifying a former stationmaster from his gait.
