I had a detective in mind, Peter Nation and a basic plot. Chambers sees things through the eyes of the killer and I see things through the eyes of the detective; it's a bit weird but a great way to get the two principal voices written with a real edge.
I'm waiting (impatiently) for Chambers to finish his current Zac case file before we can get motoring on Dust Jacket. The picture? This is Dust Jacket, our serial killer.
