Heartbeat S15E04 - Mastermind

A gang of ageing villains spot a chance for one last, glorious crime spree when the villagers leave Aidensfield en masse to support Rob in a charity football match. Meanwhile, David is nervous when he is summoned for jury service and learns the accused is an old acquaintance of Aunt Peggy's, providing her with a new way of making easy money and leaving David paranoid that Miller wants to send him to prison.
