Two-part crime drama set during the Blitz, loosely based on the memoirs of writer Molly Lefebure. When several young women are found murdered, DI Freddy Wilkins believes the obvious suspect is loner Wilfred Ziegler, but Home Office pathologist Lennox Collins and his secretary Molly Cooper have their doubts and employ ground-breaking forensic techniques to ensure the right man is brought to justice. Starring Patrick Kennedy, Tamzin Merchant, David Sturzaker and James Fleet.
