In post-war Britain, desperate men will risk everything for one last mission...
Jack Mercer once led elite commandos behind enemy lines. Now he's just another veteran struggling to survive in austerity Britain, watching his brother waste away from a disease he can't afford to treat.
When a mysterious figure named Collins approaches Jack with an audacious proposal-to rob the Irish Mail train carrying millions in unmarked banknotes-he sees one last chance to save his brother's life.
Jack reassembles his former wartime squad: Liam, the explosives expert with dangerous gambling debts; Charlie, the communications specialist betrayed by post-war life; Morris, the railway engineer fighting to save his family farm; and Bennett, the tactical mastermind with a talent for violence.
Their target: the night mail train on the North Wales Coast Line.
Their plan: to take control of the Llandudno Junction signal box and divert the train to an isolated siding.
Their promise to each other: no unnecessary violence.
But as the perfect heist unravels into a web of betrayal, Jack discovers they're pawns in a far deadlier game. Someone is using them as a diversion for something much bigger-something with roots in their classified wartime operations.
With British authorities closing in and former allies turning against each other, Jack must choose between loyalty to his men, justice for his country, and saving the only family he has left.
Some secrets should stay buried. Some trains should never be robbed.
