A man has been murdered. He is blond, blue-eyed and is wearing a white suit. His surname is White. The murdered man is dark, black-eyed and his suit is black...the same as his surname. And, as if that isn't enough, they look like perfect twins except for the details of eye colour and complexion. Two policemen are in charge of the hottest crime in London. They will cross a sea of intrigue to find out that two gangs in the city have declared war on each other and that more murders are to follow. A bizarre couple is at the epicentre of the mystery: an old man with violet-coloured eyes and a ten-year-old boy, who have the peculiar habit of only talking to each other and never addressing anybody else. Nothing is as it should be. Not everything is black or white.
