Start off with a description of the accident in almost graphic detail. A good start would be to say something like: I heard the scream and then the unmistakable noise of a car hitting a movable large object. In the split second it took me to look toward the sounds the body of a young women was literally flying through the air to land with a horrible crunch against the front of a bus travelling in the opposite direction. Although the event took but less than a 3 seconds, I saw it all in that peculiar slow motion making every detail clear to me. I rushed over to the young women and she was not looking too good with a trickle of blood coming from the corner of her mouth. In spite of the horror and speed of the accident she was still holding what looked like a leather bound note book. She was just conscious and as I knelt beside her she gave me the book and pushed under my coat. Others joined me and as we tried to make her comfortable, she died.
After talking with the police I made my way home still reliving that moment. I still had the book and when I got home I made some tea, put plenty of sugar in it, sat down and opened the book.
Written in a neat hand, in ink was what at first site was a diary but after the first page it was clearly a detailed log of what had happened to this women since April last year.
This is where you take up her story. It can be a love story, a story of being followed or threatened. The possibilities are endless.
The key is that the first paragraph has grabbed the reader and the reader will be dying to find out why this girl died.
