The art of plot procrastination is something you have to master when you're writing. You can't burn through your plot too quickly, so how do you overcome the desire to throw in each staggering revelation in your story just to get them onto the page?
It's sometimes frustrating when it's done badly. The protagonist finally locates the one person who has the answer to all the questions, and when the critical question is asked of the character, the response is often, "I will tell you everything you need to know, all in good time, but first, you must be hungry!"
This sort of thing usually ends up with the character with all the information getting murdered before he can answer said question.
How did I get round it when I was writing Spireclaw? Well, without wanting to spoil the plot and revelations in that story (Spireclaw thrives on its twists and turns and blind alleys), there were a couple of techniques which I employed. Use several angles at once. Keep several balls in the air so that the reader is never quite sure which one is going to drop. Is the twist going to be around This or That? Bring your revelations in from a perspective and angle that is unexpected. It enables you to build new perspectives on the issue at hand without having to play your trump card so quickly. I realise these are abstract concepts, but if you want to know what I mean, go and read Spireclaw on this very website, or get it from Amazon on your Kindle. Then come back and read this blog post again.
