H9. Similes and metaphors: how many, and of what kind. Both

This lens across all books

76 likely similes ('like a', 'as ... as'): 1.07 per 1,000 words. (rough estimate from word lists)

Ch 1, para 4: "My dear Jervis," he exclaimed, as we clasped hands warmly, "this is a great and delightful surprise. How often have I thought of my old comrade and wondered …

Ch 2, para 59: "I expect nothing but a conviction," replied Reuben in a calm and resolute voice, "and can face it like a man if only you do not take my …

Ch 2, para 60: "Everything shall be done that I am capable of doing," said Thorndyke; "that I can promise you. The long odds against us are themselves a spur to endeavour, …

Ch 2, para 61: Reuben Hornby held out both his hands for my colleague's inspection, and I noticed that they were powerful and shapely, like the hands of a skilled craftsman, though …

Ch 3, para 7: "A wonderful man that, Jervis," my friend observed as his assistant retired. "Looks like a rural dean or a chancery judge, and was obviously intended by Nature to …

Ch 3, para 9: "He was an in-patient at the hospital when I first met him, miserably ill and broken, a victim of poverty and undeserved misfortune. I gave him one or …

Similes and metaphors are sparse and functional. Thorndyke's mind is compared to a machine; evidence is weighed and measured. Most figurative language serves scientific or legal argument rather than lyrical effect.

Chapters: Ch 3, Ch 5, Ch 8, Ch 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)

H10. Senses used: sight, sound, smell, touch, taste. Both

This lens across all books

Share of sense words. sight 68%, sound 22%, touch 7%, taste 2%, smell 0%. (rough estimate from word lists)

SenseWords
sight411
sound136
touch43
taste14
smell3

Sight dominates: microscopes, photographs, finger-prints, physical evidence. Sound appears in dialogue and courtroom scenes. Smell, touch and taste are minimal; the poisoned cigar is tasted only in theory, never by victim.

Chapters: Ch 3, Ch 5, Ch 13, Ch 16

They would hardly make a Trichinopoly cheroot from leaf grown in the West Indies (Ch 13, para 31)

H11. Repetition, lists of three and other patterns. Both

This lens across all books

43 lists of three in the pattern 'a, b and c': 0.61 per 1,000 words. (rough estimate from word lists)

Lists of three appear in Thorndyke's deductions and evidence catalogues. Repetition of key phrases like 'finger-print' and 'forgery' builds obsession. Patterns emerge in Walter's assassination attempts: needle, cigar, typed evidence.

Chapters: Ch 13, Ch 14, 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)
I do; and I also say that it is certain that the forgery was executed by means of the 'Thumbograph. (Ch 16, para 125)

H12. Old words that may trip modern readers. Count

This lens across all books

Old forms that may trip a modern reader: whence, art, whilst, ere.

H13. Showing against telling, with examples. AI

This lens across all books

The book shows rather than tells through Jervis's observations and Thorndyke's demonstrations. The poisoned cigar is dissected on stage; the forgery is proven by reproduction, not explanation. Juliet's feelings emerge through her actions and silences.

Chapters: Ch 13, Ch 16, Ch 17

there was a sparkle of the eye and a scarcely perceptible flush of suppressed excitement and triumph which I had begun to recognise beneath the impassive mask that he presented to the world (Ch 5, para 42)
No. I am of opinion that it was not made by a human thumb at all. (Ch 16, para 30)
I do; and I also say that it is certain that the forgery was executed by means of the 'Thumbograph. (Ch 16, para 125)

H14. How much description comes before action. Both

This lens across all books

Description is minimal and woven into action. Jervis notes details as he moves: prison conditions appear during a visit, the courtroom during trial. Settings are functional backdrops to investigation and dialogue rather than set pieces.

Chapters: Ch 9, Ch 15, Ch 16

The innocent man is a negligible quantity, and no arrangements are made for him or his visitors (Ch 9, para 17)
a black-painted prison van turned into the courtyard with its freight of squalid misery (Ch 9, para 54)

H15. Filter words such as "saw", "felt", "heard". Count

This lens across all books

Filter words ('saw', 'felt', 'heard' and so on): 2.71 per 1,000 words.

H16. Shifts in tone. AI

This lens across all books

Tone shifts from friendly reunion in Chapter 1 to urgent mystery in Chapter 2, then darkens with assassination attempts in Chapters 11 and 13. The trial in Chapters 15 to 16 builds tension before resolution's quiet relief in Chapter 17.

Chapters: Ch 1, Ch 2, Ch 11, Ch 13, Ch 15, Ch 17

H17. How the comedy works. AI

This lens across all books

Comedy is dry and sparse. Polton's silent competence, Mrs. Hornby's rambling conversation, and Reuben's cool indifference to Juliet's devotion provide light moments. Humour serves character rather than plot.

Chapters: Ch 5, Ch 9, Ch 12

she's a deuced good sort, is Juliet (Ch 9, para 39)
