Having been a huge fan of I Love Lucy, it was intrigue that led me to watch her play a sexy, sassy dancer; which she played quite well. In a not so orginal plot of a serial killer in Scotland Yard, this film was dark, sophisticated, and well-acted. Ball is lured into helping the police find the poet serial killer, who has supposedly been killing off attractive dancers. She meets many strange characters in her journey to find the real killer, such as Karloff, who has a way too short role as a crazy former dress designer. George Sanders was superb as the sophisticated playboy, who must have been the model for the rich, yuppie snobs in later films. Ball falls in love with Sanders, but is he the killer? Great who-done-it that leaves you guessing until the last 15 minutes or so.
