She-Wolf of London (UK title: Curse of the Allenbys) is a 1946 American horror film produced by Universal Studios, directed by Jean Yarbrough and starring June Lockhart and Don Porter.
The title evokes the earlier Werewolf of London (1935), although, unlike its forebear, it is concerned more with mystery and suspense than supernatural horror. In the USA, the film was released as a double feature with The Cat Creeps.
Phyllis Allenby is a young and beautiful woman who is soon to be married to lawyer and boyfriend Barry Lanfield. Phyllis is living at the Allenby Mansion without the protection of a male, along with her aunt Martha and her cousin Carol and the servant Hannah. As the wedding date approaches, London is shocked by a series of murders at the local park, where the victims are discovered with throats ripped out.
Many of the detectives at Scotland Yard murmur about werewolves, while Inspector Pierce believes the opposite and suspects strange activity at the Allenby Mansion (which is near the park), where the “Wolf-Woman” is seen prowling at night and heading for the park.
Phyllis becomes extremely terrified and anxious, since he is convinced that she is the “Wolf-Woman”, deeply believing in the legend of the so-called “Curse of the Allenbys”…
“By the way, have you heard the news? A Scotland Yard man was murdered in the park by a mad woman who made a noise like an animal. The papers are full of it.”
