Undercover Girl is a 1958 British second feature[1] crime film directed by Francis Searle and starring Paul Carpenter, Kay Callard, and Bruce Seton.

His brother-in-law, Johnny Carter, discovers that the murderer was club-owner Ted Austin, who runs a blackmail racket.

There appears to be some unnecessary violence spicing the plot in the scene where Peggy's face is mutilated in a last act of revenge on the part of the villain.

Former band crooner Paul Carpenter is an amiable star of sorts and co-star Kay Callard has a passable second-string leading lady quality.

The real interest lies in the appearance in an "acting" role of Jackie Collins, now better known for writing raunchy novels.
