A Really, Really, Really Great Idea

I'm almost finished with the first draft of my WIP (the sequel to KILLER ROUTINE), and I think I'm going to come up a little short. Like about 8000 words short (that's somewhere around ten percent).

Here are some ideas I had for increasing the word count:

Add an adjective (or better yet, an adverb) to each sentence.

Use a dialog tag for every piece of dialog (you can never have too many "he said, she saids.")

More backstory! Especially up-front.

Describe the settings really, really...
