For more than fifty years, two ruthless gangs have dominated the Tyneside underworld. Initially, the Conroy and the Sayers families lived side by side in relative harmony in the West End of Newcastle, but the birth of the drug-fuelled rave culture in the late 1980s changed everything. Drunk on power and with an intense desire to take complete control of the north-east, the families went to war with one another and with anyone else who stood in their way. What followed was an orgy of mindless violence. In ''Fog on the Tyne'', bestselling true-crime author Bernard O'Mahoney explores the origins of this gangland war and reveals for the first time how and why it spiralled out of control, leaving many injured and others dead.
