Four friends make an underground short film of a man's suicide. Fifteen years later the four are forced to meet again to examine their past actions and present relationships. This is the premise of a clever thriller set in a seedy and derelict London - with characters to match. The story flashes backwards and forwards in keeping with the cinematic theme, though I did find the first person narratives at the beginning and end jarred a little. But do keep reading because it all comes back together in a great twist I did not see coming at all!
