Summer, 1892.
A journalist visited a house on the outskirts of London.
His subject was already a national celebrity: Arthur Conan Doyle, the man who gave us Sherlock Holmes.
The journalist was shown around the house, shown the manuscripts, and got Doyle talking about how he actually worked.
Here's what ended up in that article.
"Dr. Doyle invariably conceives the end of his story first, and writes up to it. He gets the climax, and his art lies in the ingenious way in which he conceals it from his readers."
The ending first.
What makes those two sentences remarkable isn't the "decide your ending" part. It's the second half — "his art lies in the ingenious way in which he conceals it." That's where the real story is.
So let's talk about that.
Ending First
Agatha Christie worked two ways: sometimes she started from the trick, sometimes from the relationships between people.
Doyle, judging by that interview, preferred the first one. Start from the trick.
Maybe that's because he wrote so many short stories.
The advantage of going ending-first is simple. You know where you're headed.
Without a destination, every road is the right one and every road is the wrong one. Which means sooner or later, you stop moving.
So you plant the goal first.
Then every line you write can be judged on one question: does this bring me closer, or push me further away?
It's not that the hesitation goes away.
The need to hesitate does.
The Real Work Starts After You've Decided the Ending
Here's where it gets interesting.
Read that second half again.
"His art lies in the ingenious way in which he conceals it from his readers."
For Doyle, deciding the ending was just the entrance to the job.
The main event came after.
Carrying that decided ending all the way to the last page without the reader noticing. That's where he poured every bit of craft he had.
And the order matters enormously here.
To hide something, you first need something to hide.
You can't practice a poker face before you've been dealt your hand.
So Doyle took his hand first. Then he designed which cards to show when, and which ones to keep face-down until the end.
The fact the reader understands last.
The feeling the reader has last.
Once those are settled up front, everything in between turns into setup pointing at that one spot.
Foreshadowing isn't something you go back and pay off.
It's something you can place by working backwards, because the goal was already there.
He Field-Tested on the Reader Closest to Him
One more thing about Doyle.
In that same interview, he mentions this.
The opening story of his next series had come out so unsolvable that he bet his wife a shilling. "You won't guess the truth of it before you reach the end."
He was betting his wife.
Testing whether his own device actually worked, on the reader closest to hand.
Honestly, that strikes me as an incredibly healthy instinct.
Nothing is less reliable than thinking you've hidden something well.
The person who wrote it knows the answer, so it always feels properly concealed.
You can reread your own draft and still have no idea whether the foreshadowing is glaringly obvious. Of course you can't. You know the answer.
So you try it on someone else. One person is enough.
If that person doesn't catch it before the end, you win. If they catch it partway, you ask where.
One shilling.
In today's terms, less than a cup of coffee. That's how lightly he was willing to put his own work to the test.
So How Fast Was He Writing?
So how fast was he actually going?
The same interview gives us numbers.
About a week per short story. Around three thousand words a day.
His hours: between breakfast and lunch, then again from five to eight in the evening.
Stop there for a second.
Three thousand words. In Japanese that's roughly six thousand characters, about fifteen pages of manuscript paper.
Every day.
And bear in mind he still had one foot in his medical practice at this point.
Why so fast?
You already know the answer.
Because he's holding the ending.
There's no time spent mid-sentence wondering what to do next, because that time doesn't exist. The design is finished. All that's left is carrying words toward a place that's already fixed.
He separated the thinking work from the writing work.
Fast writers aren't fast with their hands.
I think they're just not hesitating.
The Two Lines to Put on Paper Today
This got long. Let me sum up.
The ending of the story you're trying to write.
The fact your reader understands last.
Write those on paper.
Not in your head. On paper.
If you're not writing mystery, swap the fact for an emotion.
How do you want your reader to feel as they close the book?
Something wistful?
Something clean and resolved?
A little bit of dread?
Settle that in a single line.
From there on, the writing becomes a design job: what to reveal, and when, all aimed at that one point.
What Doyle had probably wasn't some flash of genius.
It was sequence. Ending first. Road after. That's it.
Well — to be precise, there was one more thing.
The ingenuity to keep that decided ending carefully hidden right up to the final line.
And honestly, from the writer's side, that part is the fun part.
