The plot thickens -- in lumps

National November Writing Month begins very soon, and I'm not sure I'm ready. I've been working on a plot, but it's only partially complete. I've got the basic outline, true, and some chapters are just about fully realized -- but there's this big hole in the middle.

I have no idea how the characters are going to get from the opening sequences to the final solution to the puzzle (heck, I only know some of the pieces myself).

Looks like I'll have to make this one up as I go along! Will it work? Possibly. There are as many different ways to write a story as there are writers -- which is not as large as the number of ways to write a good story...
