D4. Scene against summary: how much is shown live? AI

This lens across all books

The book is heavily scene-based, with dialogue comprising 52.5% of text. Most plot developments occur in live scenes across all 17 chapters, particularly the investigation scenes (chapters 3, 5, 10) and the trial (chapters 15 to 16). Summary is minimal.

Chapters: Ch 3, Ch 5, Ch 10, Ch 15, Ch 16

I make it a rule, in all cases, to proceed on the strictly classical lines of inductive inquiry--collect facts, make hypotheses, test them and seek for verification (Ch 3, para 13)
A finger-print is merely a fact--a very important and significant one, I admit--but still a fact, which, like any other fact, requires to be weighed and measured with reference to its evidential value (Ch 3, para 21)

D5. Action against reflection, per chapter. AI

This lens across all books

Action dominates early chapters (2 to 3, 8, 11, 15 to 16) with investigation, meetings, and trial scenes. Reflection increases mid-book (chapters 6 to 7, 12) as Jervis wrestles with duty versus love. Late chapters balance both as the case resolves.

Chapters: Ch 2, Ch 3, Ch 6, Ch 7, Ch 12, Ch 15

you are so kind, and I feel that you are really my friend and Reuben's (Ch 7, para 21)
How can a man who is thinking of a woman morning, noon and night; whose heart leaps at the sound of her coming (Ch 17, para 40)

D8. Chapter endings: cliffhanger, question, reveal or quiet close. AI

D9. Chapter openings: in scene, in summary, or after a time jump. AI

This lens across all books

Most chapters open in scene with characters present and speaking or acting. Chapter 1 opens in scene at the Temple. Chapter 10 opens with Thorndyke's recovery then moves to action. Few chapters use summary openings; the narrative favours immediate immersion.

Chapters: Ch 1, Ch 2, Ch 3, Ch 10, Ch 15, Ch 16

D10. Do chapters and sentences get shorter near the climax? Count

This lens across all books

In the last fifth, chapters run at 1.94 times the length of earlier ones, and sentences at 0.91 times. So things speed up near the end.

D11. Dialogue density against pace. Count

This lens across all books

Link between dialogue share and chapter length: 0.25 (1 is a perfect match, 0 none). Between dialogue share and tension: -0.33.

Time jumps are signalled through brief narrative bridges rather than explicit markers. Chapter 6 jumps to the trial hearing. Chapter 12 notes 'a week away' before trial. Chapter 14 opens 'on the morning of the trial'. Jumps are usually one or two sentences.

Chapters: Ch 6, Ch 12, Ch 14, Ch 15

D13. Info dump spots: long runs with no action or speech. Both

This lens across all books

0 stretches of 900 words or more with no speech at all. These are where description, summary or backstory pile up.

Info dumps are rare due to high dialogue share. Chapter 13 contains the longest expository passage as Thorndyke dissects the poisoned cigar and deduces facts about the assailant. Chapter 3 has moderate exposition about the Thumbograph. Most chapters balance action with brief explanations.
