Lo sparviero di Londra

I was 'lured' into this one by its cast - Lucille Ball in a dramatic role, opposite George Sanders, and with Charles Coburn and Boris Karloff in supporting roles. I wasn't disappointed. It's a nice mystery/drama where a serial killer in London finds his victims through personal ads, and then boasts about it to the police with poetry reminiscent of Charles Baudelaire. Ball plays an American working in a dancehall who begins working undercover for the police when one of her friends becomes a victim. That bit is a little contrived, but I liked her pluckiness and how she stands up to a variety of creepy male behavior (in the dancehall, various ogling, and with some of the men she meets via the personal ads). There are some standard tropes - Ball's extraordinary powers of observation, Coburn being the distinguished sleuth who engages in a cat and mouse game with the criminal, etc - but the script is intelligent and has some interesting turns. Just don't go into it with the expectation that it's film noir, and enjoy the performances.
