When you create your 
characters, you often do a lot of work to figure out their 
backstory—everything that happened to them before the story began.
The temptation is to tell 
the reader all that backstory as soon as you can. Because it’s super 
interesting to you, it’s easy to assume that it’s super interesting to 
your reader. 
The problem is that your 
reader wants to get into the main story first, to get emotionally 
connected to your characters. Until your reader cares about the main 
story, he or she doesn’t care about your backstory. Backstory is 
incredibly important, but it’s like salt in the soup. A little goes a 
long way.
So how do you handle that? How much backstory should you tell? When should you tell it? What do you do with the backstory you never tell your reader? 
To squeeze it all down to one critical question: How do you know how much backstory to write into the scene you’re working on right now? 
My Rule of Thumb for Backstory
My working rule of thumb 
is to introduce backstory “just in time.” Meaning that when you’re 
writing a scene where the backstory plays a crucial role, you tell the 
reader whatever bit of backstory you need right when you need it. Just 
that and no more.
This is a rule of thumb, 
not an ironclad rule. Of course you’ll sometimes need to introduce 
backstory before you need it. But if you don’t need to, then don’t.
The reason for telling 
backstory just in time is that backstory tends to slow down your story. 
It’s a good idea to not slow it down any more than you have to.
An Example of Just in Time Backstory
A month or two ago, I read the novel The President is Missing,
 by James Patterson and Bill Clinton. I thought it would give me an 
inside look into the job of being President, and I was right. My working
 assumption here is that Patterson did all or most of the writing and 
Clinton provided the background info, which seems the most likely way 
they split out the duties of coauthoring situation. So in my analysis 
below, I’ll refer to Patterson as the writer, even though of course 
Clinton is a coauthor.
The protagonist of the 
book is President Jonathan Duncan. Cyberterrorists have targeted the US 
with a lethal computer virus that could bring the country to its knees. 
The President and eight of his closest advisors know the virus exists, 
and they’re desperate to prevent a catastrophe. The President also knows
 that one of the eight is a traitor, which makes his job even harder. 
He’s got to save the country and unmask the traitor, and he has two 
days. Congressional leaders aren’t in on the secret, so all they know is
 that the President is acting very weird and could possibly be 
committing treason.
I read the book a couple 
of times. The first to enjoy the story. The second to take it apart and 
see how it works. James Patterson is a wily author who uses every trick 
in the book to weave unexpected twists into his stories. I wanted to 
study his set of tricks. 
On my second read through 
the book, I took note of Patterson’s careful handling of backstory. Very
 often, he brought it into a scene exactly when he needed it.
A nice example is the opening chapter, which begins with this bit of dialogue: “The House Select Committee will come to order …”
This is a very tricky scene
 to get right. The author has to introduce the protagonist, President 
Duncan, make it clear that he is genuinely the good guy in this story, 
and introduce the predatory congress-critters who are out to get the 
President. All from a cold start in which the reader knows nothing about
 the President, his congressional opposition, or the cyberthreat facing 
the country.
This scene could very 
easily be a boring encyclopedia article on how a congressional 
investigation goes. But it isn’t. It’s a reasonably fast-paced scene 
that puts our hero in danger immediately, without confusing the reader. 
How does Patterson make this scene work?
He does it by mixing in action, dialogue, and carefully measured-out bits of backstory.
The first paragraph is the snip of dialogue I already quoted above.
Then comes a paragraph of 
interior monologue about the sharks on the House Select Committee and 
the President’s fears in dealing with them.
Then three quick paragraphs
 of backstory, direct quotes from the previous night, when the 
President’s chief of staff urged him not to testify. This counts as 
backstory, but it’s told as dialogue—essentially a mini-flashback.
Then there’s a paragraph 
showing us what the President sees, thirteen angry congressmen. The 
paragraph zooms in on the nameplate of the chairman, Lester Rhodes. 
Then there’s a paragraph 
of backstory about Rhodes, explaining why he’s so dangerous to the 
President. This is told as interior monologue, so it’s in the 
President’s voice, and it’s told in a way that makes you empathize with 
the President. You don’t have to be told the President is the good guy 
of this story, because you feel it.
Then there’s another 
paragraph of action. The President adjusts his mike so he won’t have to 
lean forward. He’s paying attention to his body language, doing 
everything he can to avoid looking weak. This is the sort of thing that 
real presidents have to think about.
Next is a paragraph of interior monologue. The President is prepping to be grilled.
The scene continues like 
that for the rest of the chapter. There’s a bit of 
action/dialogue/interior monologue. Then there’s a bit of backstory to 
explain what the heck is happening.
This could easily go wrong, and there are two ways to fail:
- Show too much action and dialogue, without enough backstory to understand what’s happening. This fails by confusing the reader.
- Tell too much backstory, without enough action and dialogue to keep the story moving. This fails by boring the reader.
There’s a fine line you 
have to walk in this kind of scene. I’ve read the scene several times, 
and my judgment is that Patterson nailed it. The scene is quite long, 
but it’s compelling and reasonably clear at all points. And it ends with
 a cliffhanger that forces you to turn the page.
In such a complex first scene, I don’t see any way to do it better. 
Breaking the Rule of Thumb
For most of the story, 
Patterson follows our rule of thumb very closely. He introduces 
backstory just in time. But there are certain points at which he 
doesn’t. There are a few places where he gives you a bit of backstory 
for no obvious reason.
But there is a reason. If 
you read the book, be watching for those apparently unnecessary bits of 
backstory. Some of them are clues that will turn into major surprises a 
hundred pages down the road. Or two hundred pages. 
Not all of them are clues.
 But some of them are. A good author seeds in clues far in advance of 
the surprise. Then the reader doesn’t feel cheated when he realizes he’s
 been misled. Because the clues were there.
A big part of the art of 
writing major plot twists is seeding in clues to plot twists a long time
 in advance, often using what appears to be innocent backstory. 
I’m not in the business of
 spoiling other authors’ plot twists, so I won’t give examples of just 
how Patterson worked his magic with his plot twists. But study how 
Patterson hides his clues in the backstory, doing his best to make you 
slap your head when you reach the twist and say, “Dang! I should have 
seen that coming!”
And if you’re observant, you will see it coming and you can bask in the glow of your own cleverness—until you hit the next twist that you didn’t foresee.
Enjoy the Ride
You may or may not buy 
into the idea that a supervirus can infect machines running a wide 
variety of operating systems—Mac OS, Windows, Linux, and numerous other 
flavors of Unix. But whether you do or not, you can enjoy the story and 
learn from the master. This is a political thriller, not a 
technothriller.
Have fun!
