Adding subplots to a novel is all about taking the main plot you constructed earlier and adding dimension and complexity to it.
The good news is that you have already done most of the hard work. After reading and absorbing the articles in the plotting section, you will be perfectly capable of writing a watertight central plot for your novel. Adding subplots uses exactly the same skills and knoledge - only on a much smaller scale.
This article looks at three important areas...
Let's start by stating the obvious: a subplot is precisely the same thing as a novel's central plot, only it is much smaller in scale.
And when I say it is the "same thing" as a central plot, I mean that you use the same 10-Step Guide to Plotting a Novel to build it...
You begin by introducing the character in their ordinary world. Next, something happens to disrupt the status quo. And so on.
In some novels, telling the main plot apart from any secondary plots isn't always easy - they can seem equally important.
Beware, though, of any secondary storylines overwhelming the main plot. They are there to enhance and strengthen the main story, not to compete with it.
The main plot should always begin and end the novel, and any minor plots should happen within these "bookends".
A subplot can be told from the viewpoint of the story's central character (the one the main plot is "about"), or it can be told from the point of view of one of the lesser characters.
For example, if you are writing a crime novel...
Incidentally, you might think that this last one is actually a part of the main plot - just seen through different eyes - but it isn't.
A plot, remember, is about a character pursuing a goal, encountering conflict and reaching a resolution...
The two plots might have the same event in common - the robbery - but each character is coming at it from a very different perspective.
Think of a novel like a length of rope. At one end is the beginning and at the other the ending.
The rope itself is actually made up of several mini-ropes braided together - these represent the main plot and the subplots. The rope as a whole represents the sum total of all plot lines in the novel.
(It isn't a perfect analogy because the strands in a rope are of equal thickness and length, whereas a main plot is fatter and longer than the lesser plots. But you get the idea.)
The important thing is this: although the strands are all interweaved, they actually remain separate.
In other words, it should always be possible to remove an individual storyline from a novel without the story as a whole collapsing. It might weaken it, just as removing a strand from a rope would cause it to lose strength, but the story should still make sense.
"The first job of a sub-plot is to add a dimension to the story which the main plot lacks. Because fiction is a tidied-up version of life, it is easy to stray into a simplistic portrayal of events which does justice neither to the complexity of real life nor to the intelligence of your readers."
- Nigel Watts
First, and most obviously, secondary plot lines are useful in turning what might otherwise be a very slender novel into something more substantial.
Short stories usually consist of one plot, and a very simple one at that. Turn this simple plot into a much lengthier one and you will have something recognizable as a novel on your hands.
But for a truly complex story - which most novels are - you need these multiple strands running through it.
But beyond merely bumping up the word-count and adding complexity to the story, there are other, stronger advantages to adding subsidiary plot lines to a novel...
For one thing, they help with the characterization - at least, the subplots told from the principal character's viewpoint do.
If the crime novel I talked about earlier dealt only with the casino robbery, we would only get to see the leading character when he was "at work". By including the romantic story about persuading his wife not to leave him, we get to see a very different side to his character as he tackles a very different problem.
Secondary story lines can help with the portrayal of theme, too.
Let's say that the crime novel's theme is "being true to yourself". The hero might believe that he wants to rob the casino so that he and his wife can retire to Italy in luxury, but what he comes to discover as the novel progresses is that he is addicted to the buzz of his job and couldn't give it up if he tried.
That is the main plot dealt with. But having other plots (or other strands in the rope) allows the writer to explore this theme in more depth and from slightly different angles...
So in the romantic sub plot, the hero further realizes that his wife doesn't want him to leave the robbery business any more than he wants to quit it.
They would be bored in Italy inside a month, and they both know it. They just haven't admitted it until now.
And in the accomplice's story, he might have thought he blamed the casino manager for the death of his best friend, but the truth is that he himself is the one to blame. Revenge seemed a noble motive, but the truth is that he is doing this for the money, not for his dead friend.
With only one plot in a novel, it would be difficult to explore your theme from several different angles.
Here is another advantage of subplots...
They keep the readers reading. However well you construct a plot, there will always be slower parts punctuating the exciting parts.
Now, slow parts in a story are good to an extent, in that they help to regulate the pace. But if a slow part threatens to become plain "dull", you can always let the events play out "in the background", as it were, and switch to an exciting minor plot line instead.
Last but not least, secondary plots add variety to a novel.
If the main plot is deadly serious, for example, introduce a light-hearted or even a comic subplot for some occasional light relief.
Or if the main plot is characterized by violence and non-stop action, make one of the minor plots more gentle and reflective in nature.
The key to not becoming hopelessly confused when plotting a novel with several plot lines running through it is to treat each plot - the main plot and all the subplots - as entirely separate mini-novels.
Begin by working out the main plot, then put it to one side and repeat the process for each of the lesser storylines.
(Of course, there will be a large amount of common ground between the plots, but focusing on each one as a separate story and ignoring the others - at least initially - will result in a much stronger novel. Trust me.)
Next, return to the main plot and roughly divide it into chapters (a chapter usually ends at the resolution of a scene). I like to do this with paper and scissors and lay out the chapters on the floor, in a long column, but you could do it on the word processor if you prefer.
Next, take your first subplot and also split it into chapters. Then it is simply a question of inserting these chapters into the body of the main plot...
And so it continues...
First, you add one subplot to the main plot, then all the others.
There will be a lot of switching around and merging and altering here, but you should end up with a "Master Plot" containing the main plot and as many subplots as you have written.
The Master Plot is like the rope I mentioned earlier, and the strands within the rope are the individual plots - all of them essentially separate, but all of them braided together to form a whole that is greater than the sum of the parts.
For a while, a particular strand will be at the forefront. Then it will loop out of sight again to be replaced by a different strand.
And that is how subplots are created.
