Little Red Monkey (1955)

Richard Conte is the visiting American actor for this decent enough British-made thriller. He, "Locklin", is charged with ensuring the safe transfer of a defecting Soviet nuclear scientist "Dushenko" (Arnold Marlé). Simultaneously, a spate of murders is occurring in London and Scotland Yard (Russell Napier) initially baffled, soon discovers that there is a connection and so he and "Locklin" have to work together to thwart the daring plot - starting with just a monkey's paw print for a clue! It's a bit formulaic this, there is a journalist (Colin Gordon) in on the search too; a kidnap and some good old fashioned thumb-screw techniques as the baddies try to elicit the location of their prey. At times it can look little better than a filmed radio play, but at just over the hour, it doesn't hang about. The writing and the acting do their jobs, and though we know pretty early on who is who, it's still quite an enjoyable cold war drama.
