Heartbeat S12E13 - For Whom the Bell Tolls

Blaketon is back in Aidensfield following his time away and immediately finds himself embroiled into a dangerous investigation when Lord Ashfordly calls on his P.I. services when explosives go missing from the local quarry ahead of a Defence Minister's official visit, causing tensions to boil over and putting the former sergeant in mortal peril when he crosses swords with a deadly new foe. Meanwhile, Vernon, Bernie, David and Dr Alway become bell ringers at the local church, but they soon upset a local man when their practice sessions interfere with the sale of his cottage.
