The Phantom Fiend ~ 1932 -BW

QUICKIE: (singsong voice): Your lodger is a psycho.

PLOT: (from IMDB): This was the first sound remake of the Hitchcock silent classic inspired by the Jack the Ripper legend. Ivor Novello, who played the title role and headed the team writing the script, was in the original as well.

SUMMARY: A family gets a new lodger who just happens to be slitting the throats of the local girls. Of course the daughter falls for him and they begin courting. Much to the chagrin of her news reporter-boyfriend. He suspects the lodger is the murderer and rouses the authorities to pursue him. In a suspenseful ending we find out it isn't the lodger, but his psycho brother that is the murderer. The lodger has come to the city to stop his crazy brother. Eh, some families!
