Murder on the Homefront. Set during the London Blitz of 1940, Murder on the Home Front is a vibrant, original crime drama, where criminals can use the blackout and devastation to hide their darkest activities. As the Luftwaffe drop their bombs, below people are literally getting away with murder. Dr. Lennox Collins (Patrick Kennedy, Bleak House) is a pathologist new to murder cases, obsessed with pursuing the truth through all means available and Molly Cooper (Tamzin Merchant, DCI Banks) is not only the first secretary to a pathologist, she is the first woman allowed into a very male world. Together they discover a serial killer at large under cover of the Blitz and Lennox has his work cut out convincing the police to have faith in his methods and theories.
