Phantom Fiend (a.k.a. The Lodger) 1932
A maniac, who stalks and murders street-women at night, is terrorizing London. Michael Angeloff, a Hungarian musician, takes lodgings with the parents of Daisy Bunting, and a romance develops between the girl and Angeloff. The terroristic murders continue and circumstances gradually point the finger of suspicion at Angeloff, as the only clue the police have is that the killer is a foreign musician.
