It may not interest you technically but for a large section of humanity it could be a matter of life and death. The British government asks entomologist Frances Gray (Margaret Lockwood) to go behind the Iron Curtain and examine insects that might be used as carriers to spread disease in germ warfare. Grudgingly accepting the job, Frances goes undercover as Frances Conway, a tour director looking for potential holiday destinations and meets tough American reporter Bill Casey (Dane Clark) in the process. Unfortunately, the chief of police Razinski (Marius Goring) quickly sees through Frances’ flimsy cover. Then her contact is murdered and his body left in her hotel room and Frances is taken into custody, prompting Casey to come to her aid… A few months ago some people were shot accidentally in the woods. It was terrible. A vehicle for Lockwood after a period doing theatre, Eric Ambler loosely adapted one of his novels (The Dark Frontier), changed the gender of the protagonist and it’s a spirited adventure. The Ruritanian setting hints at the comedy style, returning Lockwood to a kind of thriller along the lines of The Lady Vanishes – enhanced by the casting of Naunton Wayne as Frances’ recruiter, Hedgerley, Wilfrid Hyde White (after The Third Man) and Goring’s performance as a comedy police chief, enlivening the playfulness. Like The Third Man, Ambler’s script makes a meta issue of storytelling, there’s a torture scene in a TV studio-like location and there are references to soap opera and a character called Frank Conway, the star of a radio serial that Frances listens to for her little nephew and for whom she is re-named. Nicely done with a good mix of intrigue, suspense and fun led by Clark as the inadvertent hero of the situation. Directed by Roy (Ward) Baker. You just can’t do things like that in real life.
