I'd been trying to think of a detective/cop/traffic warden idea that I could send to a French publisher. All to no avail I'm afraid. That was until I walked to Somerfield for some basic provisions and I noticed someone driving out of the car park while obviously not looking where she was going. Then it hit me, a germ of an idea, something that I could mould and perhaps use. Moment of Inspiration Number 522.

(I should reiterate it was the idea that hit me, not the car.)
