This new thriller is loosely based on the memoirs of Molly Lefebure, who was secretary to Home Office pathologist and pioneer of modern forensics Keith Simpson during World War II. From a ratings point of view, it’s a shrewd commission – there will always be a certain level of audience take-up for gloomy atmospherics, air raid sirens and spivs in fedoras. As a drama, though, this will need time to bed in.
Doctor Lennox Collins (Patrick Kennedy) may be a forensics man but he’s a TV detective in spirit – maverick, unpredictable and not entirely risk averse. In fact, the blurring of the lines between his emerging profession and the more stolid police work that surrounds him is one of the main sources of intrigue. One suspects that Lefebure would be delighted with her fictional counterpart, the flighty and vivacious Molly Cooper (Tamzin Merchant) who emerges as Collins’s partner in crime during this opener. Three women are dead. But can the pair dodge the Luftwaffe for long enough to nail the killer? Very much of its type, but perfectly watchable.
