My Name Is Julia Ross

Julia Ross secures employment, through a rather nosy employment agency, with a wealthy widow, Mrs. Hughes, and goes to live at her house. 2 days later, she awakens – in a different house, in different clothes, and with a new identity. She’s told she is the daughter-in-law of Mrs. Hughes, and has suffered a nervous breakdown. I’d Julia really ‘Julia’, or, is it true, that she’s lost all memory of who she is?
