Green for Danger Blu-Ray

Classic British murder mystery starring Alastair Sim.
In August 1944, German flying bombs are raining down on London.
Directly under their flight path is a small cottage hospital, where the tension is becoming unbearable for the dedicated team of surgeons and nurses.
Their close-knit community is torn apart by jealousy and terrible secrets, and when the local postman is brought in, delirious but trying to impart an urgent message - the murders begin.
The eccentric and irreverent Inspector Cockrill (Sim) of the Kent County Police is called in to investigate a truly baffling case where everyone has secrets, but where no one appears to have a motive.
