Contrived potboiler (complete with specifically timed amnesia) is elevated by the mesmerizing presence of Kathleen Byron; I've been trying to see as many of her films as possible lately, and here she invests a lot in what appears to be an ordinary character. It was directed by John Guillermin, who later made, among others, one of my favorite films of all time, "Death On The Nile": this early work is fairly competent, although there are some strange editing cuts that suggest possible trimming for the film to fit into a pre-ordained "second feature" length (it runs under an hour). **1/2 out of 4.
