Master Plots

I have a book that I bought from Writer's Digest Book Club. The book is titled 20 Master Plots and how to build them by Ronald B. Tobias. It takes the classic plots of literature and breaks them down and tells you how to build a story using the same type of plot.
My problem is this:
My characters never want to follow a simple plot line.
Take Moby Dick for instance:
It is considered a pursuit plot. According to Mr. Tobias "The pursuit plot is the lieterary version of hide-and-seek." "One person chases another."
So, you have three phases of the chase - the stakes of the race, the pure chase, and the resolution of the chase.
Simple, huh?
Not for my characters. Oh no. No simple chase for them. There has to be the chase, and a traitor, and a pseudo-traitor (you know - the one you think is the traitor but really isn't), and then we have a monster who chases the chaser and the hero who chases the heroine and cathches her but not before she catches the monster who was chasing her while she was chasing the thing that the chase is all about.

Well, you get the idea.
I was once told that I have a convoluted, devious, and totally insane mind.
If you read Prophecy of Vithan available with Cerridwen Press You will see my mind at work. My current wip Stone of Cruento is even more convoluted, devious and totally insane. However, there is one difference. Stone of Cruento is going to be hot hot hot. So it will probably be offered through Ellora's Cave.
Now, how would you characterize a simple pursuit plot with lots of sex? Hmmmmm,
