Young photography student Josh Hetherington-O’Keefe is out walking his border collie Izzy over the common at dawn and photographing the wildlife when Izzy becomes interested in a pile of rags dumped beside the rushes. On closer inspection Josh sees that it is the body of what looks like a middle aged man and shaken by the discovery he calls the police. There is no identification on the body. All that there is is a wallet containing a few pounds, a photograph, and a key.
