Blood Will Out (S02E04)

Idyllic village life is propelled into turmoil when two opposing traveller clans descend upon the inhabitants of Martyr Warren. DCI Barnaby and DS Troy are forced to investigate when local magistrate and principal adversary of the new vagrant population, Hector Bridges, is found shot dead at his house. As the majority of the village had been watching a chariot race between the rival clans at the time Hector was killed, there are a limited number of suspects. Or so it seems. (Madman Entertainment)
