World War II was in full swing. This means that the topic of spying and conspiracy theories was heated to the max.
It implies that the simplest story could be blown up into a national security issue. That was the time. A lot of things were implied.
A girl leaves the orphanage and starts looking for her sister. Isn't that the setup for a serious melodrama? Well, it's not. Mark Robson is modeling a very different line.
This picture is about a cult. And not any special religion, but the very people who worshiped the very one who once said non servium.
In this case, the whole mystical and sectarian background is only assumed. Just as likely, instead of the villains identified in the movie, they could have been spies, maniacs, or other freaks.
Robson constantly increases the tension without rushing to introduce us to the mysteries of the plot. We are simply immersed in a new reality, which outwardly does not differ from everyday life.
And there is nothing new in this style. The movie is very reminiscent of Jacques Tourneur's 'Cat People'. But just not in the story - visually and staged.
This is not surprising, because Robson worked as an editor for Jacques Tourneur (on his top films - 'Cat People', 'I Walked with a Zombie' and 'The Leopard Man').
