The genre - mystery/humor

The opening scene - she is on a plane from Europe to USA.

I'll spend a bit of time thinking about character and basic plot but I think I'll let most of the action be dictated by the character. (That happens anyway. Why fight it?)

We aren't supposed to let the inner editor in the door (and that's why I bought an Alphasmart Neo) but I will have to get the first several paragraphs right. I need a strong opening or I just can't proceed.

(The NEO is a word processor which allows one to see just a few lines of text. Perfect for writing in coffee houses as it runs 700 hours on 3 AAA batteries.)
