The Narrowing Circle is a 1956 British second feature ('B')[1] crime film directed by Charles Saunders and starring Paul Carpenter, Hazel Court and Russell Napier.

Crime writer Dave Nelson is having a bad day – ordered to share his office with ambitious rival Rosemary Speed, brushed off by the pretty food editor Laura Martin, and passed over as editor of a new magazine in favour of handsome Bill Strayte, who enjoys the affections of Miss Martin.

However, when Crambo is unable to verify the existence of Christy or other details of Nelson's story, things begin to look bad.
