Thorndyke and Jervis inspect Jeffrey Blackmore's chambers, discovering a pencil stub, fragments of a watch-glass, and small beads that suggest recent activity.

What happens

Thorndyke and Jervis inspect Jeffrey Blackmore's chambers, discovering a pencil stub, fragments of a watch-glass, and small beads that suggest recent activity. Stephen Blackmore provides context about his uncle's habits, including his use of Chinese ink for cuneiform inscriptions. Thorndyke explains his open-minded, scientific approach to investigation, comparing it to a medical examination for unexplained symptoms.

Themes in this chapter

  • Scientific Method and Forensic Investigation

    Thorndyke's systematic collection of physical evidence (pencil, glass fragments, beads) and his insistence on keeping an open mind exemplify the scientific method applied to legal investigation.

  • Deception and Concealment

    The discovery of hidden objects (beads, watch-glass fragments) in Jeffrey's chambers hints at concealed activities or visitors, suggesting deception.

  • The Limits of Perception and Evidence

    Jervis's initial inability to see significance in the pencil stub and Thorndyke's caution against premature conclusions highlight the limits of ordinary perception and the need for careful evidence analysis.

Key passages

  • A man of science, Mr. Blackmore, expects nothing. He collects facts and keeps an open mind.

    A scientist does not start with expectations; instead, he gathers data without bias.

    Thorndyke explains his investigative philosophy to Stephen Blackmore.

  • I am a mere legal Autolycus, a snapper-up of unconsidered trifles of evidence.

    I am like a scavenger of small, overlooked details that may be important evidence.

    Thorndyke humorously compares himself to Autolycus, a character known for collecting odds and ends.

  • It is surprising how difficulties, and even impossibilities, dwindle if you look at them attentively.

    When you examine problems closely, they often become less daunting and more solvable.

    Thorndyke advises Jervis on the value of careful attention to seemingly impossible cases.
