Gus Dury is a changed man. He is off the Edinburgh streets and back with estranged wife, Debs. He has promised her that he won't get involved in any more dodgy cases which the police can't or won't solve. And above all, he's off the drink. In his pocket at all times is a half bottle of Scotch, but although the label is worn to shreds, he has never so much as loosened the cap. Then his brother Michael is found dead with a bullet in his heart and Gus' life begins to unravel all over again. How can he keep the promises he has made and still avenge his brother's murder? ''Loss'', Tony Black's third novel about washed-up hack turned private investigator Gus Dury, is absolutely gripping - a labyrinth of violence, secrets and emotion. It is a true rollercoaster of a read.
