Natural Justice

Cryer and Keane pursue a drink-driver responsible for the death of a young Asian woman. When they interview the registered owner of the car, she denies all knowledge of the incident, despite the car having been driven off with the keys inside. Their strongest lead comes when McCann and Jarvis arrest a noisy neighbour for breach of the peace and assault, and during a search, they find a bottle of homemade spirit which matches a bottle found under the driver's seat of the car which killed the woman.
