A few days ago in Arthur Conan Doyle’s A Study in Scarlet, I found an account of Sherlock Holmes performing one of his earliest deductions, at exactly the middle of Part I. You can read about it here.
Halfway through Part II of this short novel, Doyle wrote a short paragraph that was not about scientific deduction but rather about an eerie countdown, guaranteed to keep the reader turning pages. The character John Ferrier is given a deadline – 29 days – to hand over his daughter in marriage to one of the Mormon men. The next morning, at the breakfast table, his daughter points upwards:
In the centre of the ceiling was scrawled, with a burned stick apparently, the number 28. . . . That night he sat up with his gun and kept watch and ward. He saw and he heard nothing, and yet in the morning a great 27 had been painted upon the outside of his door.
Arthur Conan Doyle’s A Study in Scarlet is the first of his novels about the fictional detective Sherlock Holmes and his partner Dr Watson. I turned to the physical centre of the book to find its change of direction, and came across a long paragraph describing a Mormon caravan of wagons, horses, walkers, and toddlers, all making their way towards the West of the great North American Continent. The Mormons are a source of some major players in the story.
However, the novel has two parts, and I found at the centres of Part I and Part II the kind of mysterious statements that urge the reader to read on and discover how Sherlock solves the crime.
Halfway through Part I, a shonky detective, Lestrade, believes a murderer has written part of the name Rachel on the wall, in blood. But Sherlock’s logical reasoning produces a different theory on how the man was murdered:
“Poison,” said Sherlock Holmes curtly, and strode off. “One other thing, Lestrade,” he added, turning round at the door: “‘Rache,’ is the German for ‘revenge’; so don’t lose your time looking for Miss Rachel.”
