In the turn of the century in London, the aristocratic lawyer Barry Lanfield (Don Porter) proposes to marry the heiress Phyllis Allenby (June Lockhart) and she accepts. Phyllis lives in the family manor with her "aunt" Martha Winthrop (Sara Haden), her pseudo-niece Carol Winthrop (Jan Wiley) and the housemaid Hannah (Eily Malyon).
Out of the blue, dreadful murders happen in a nearby park and Detective Latham (Eily Malyon) believes that they are victims of a werewolf or a she-wolf, but his superior Inspector Pierce (Dennis Hoey) says that they are victims of an animal. Meanwhile, Phyllis finds blood on her hands, and her shoes and clothing dirty and she believes that she may be killing people under the influence of a family curse. Who might be the serial-killer?
"She-Wolf of London" is an entertaining mystery movie but with neither horror nor she-wolf as the title suggests. The dramatic story is not bad but frustrates fans of horror movies. My vote is six.
Title (Brazil): "A Mulher-Lobo de Londres" ("The She-Wolf of London")
