Fans of Lucy will be surprised to see her in this "re-discovered" thriller as I was. I knew she had done one film noir in 1946-"The Dark Corner" where she played a private dick's secretary. She was good in it, playing it straight. But this one I had read about but it was so obscure (not even turning up on TV) that I figured I'd probably never see it. I had also read that she didn't like this film because it was so morbid. Kino has resurrected it on video then DVD and it's wonderful. Not really morbid (maybe to her it was) but it is a serial killer tale set in foggy London and she is a tough, been-around American showgirl stranded there when her show folds. While working as a taxi-dancer, her roommate disappears and is later found to have fallen prey to a madman who lures pretty girls to their deaths through the personals and then sends Scotland Yard twisted clues based on morbid poetry. Ball is excellent as the detectives use her as a decoy to trap the killer and the cast features Boris Karloff as a mad clothes designer(!) who tries to use her to model his designs for his "critics"---actually an empty room save for his dogs. Karloff is one of many strange characters she encounters answering the personals looking for the killer...great cast all around. Lucy is just wonderful.
