Heartbeat is set in the 1960s, in the fictional Yorkshire town of Aidensfield. The first seasons focus on the lives of London policeman Nick Rowan, who moves to the village with his doctor wife Kate. Nick's police colleagues feature in the series, under the leadership of the crusty but kind-hearted Sergeant Blaketon. Blaketon's nemesis is Claude Jeremiah Greengrass, poacher and occasional small-time fence. Greengrass is a regular patron of the Aidensfield Arms hotel, run by George Ward and his pretty niece Gina. It's here at the pub that we see much of the day-to-day social interaction in the series. Heartbeat is based on the Constable books by Nicholas Rhea.
