# X: Polton Is Mystified explained — The Red Thumbmark

> Chapter companion for The Red Thumbmark by R. Austin Freeman.

## What happens

Jervis returns from a visit with Juliet Gibson, who reveals that she cut her finger in Mr. Hornby's study on the day of the diamond robbery, and that Reuben Hornby helped bandage it, leaving bloody fingerprints on papers. 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. Later, Jervis reflects on his growing feelings for Juliet and her frank, affectionate manner, while also noting that Walter Hornby may have sold his mining shares before a slump, raising questions about his role in the family's financial troubles.
