The interesting part of this quota quickie is the presence of Philip Saville. He plays Edward King, a crime writer who is engaged to marry Joan. The sister of Inspector Lawson (Dennis Price.)
Joan had a whirlwind romance with Edward who is struggling writer and helps out Lawson in his latest case.
A series of attacks on young well to do women, all taking place at 3 O'Clock in the morning. The women were killed and robbed.
The dead women all left London nightclubs just before they shut. Edward notices a pattern regarding the names of the clubs.
Only Inspector Lawson soon suspects Edward King himself. He uses his own sister as bait to trap Edward.
It was surprising to see Price doing B movies so early in his career. This is cheap and looks cheap. It even drags out its short run time. The twist at the end is hard to take and is off the wall.
Philip Saville gave up acting by the end of the 1950s. He made his name as a television director. His landmark dramas include Boys from the Blackstuff and The Life and Loves of a She-Devil.
