Two rival gangs are reeling after one leader is found murdered. And two brothers, never two more unalike brothers, have unfinished business with one another. Former detective Brendan Foley and his successor DI Iona Madison are determined to bring the gangs plaguing Warrington to justice. Combining their knowledge with National Crime Agency resources in Jeremiah Salix and an IT genius, they are hell-bent on stopping the bloodshed. But after finding a witness to a gang leader's murder, time is precious. But the witness is in a coma. The police and NCA must protect them at all costs, before anyone else finds out they are still alive. Having risked his career, and having now almost lost his remaining family, Brendan is willing to do anything to bring the remaining gang members to justice. But there is the small matter of his brother, Ross; a man steeped too far into family-run Warrington gang to ever leave. But when the team learn of a mysterious 'Twilight Express', they become convinced something huge is on the horizon. And Brendan's own son has developed a fascination with what his Uncle Ross is really like. This is gritty northern crime with ample heart: the heart-pounding final chapter in a war spanning across cities, gangs and families in the ultimate fight for justice.
