You're probably wondering what that is.
I came up with the concept some time ago. It is very important for all stories.
Ask yourself the question, how does one keep a sausage interesting to the dog that is running after it?
It might seem like a stupid question.
The trick with stories is to keep the so-called 'sausage', AKA the story, interesting.
My answer to the question above would be to keep bobbing and weaving, and sometimes let the 'dog', AKA the reader, get close to it before snatching it away again.
This means that you let the reader they've got the answer to something mysterious that is happening, but then it turns out that it wasn't the answer at all. One must keep leading them on until the end, which is when the 'dog' gets the 'sausage'.
