The Late Edwina Black

The Late Edwina Black U.S. The Obsessed is a 1951 British drama film, directed by Maurice Elvey and starring David Farrar, Geraldine Fitzgerald and Roland Culver. The film is a costume murder mystery set in the Victorian era and was adapted from a stage play by William Dinnie and William Murum.

Inspector Martin Culver determines to get to the bottom of the case and his suspicions obviously fall on Gregory and Elizabeth. In the absence of concrete proof of their guilt, he sets out to trap them, hoping that they will inadvertently implicate themselves. A complicating factor arises when it is discovered that the housekeeper Ellen Jean Cadell has been keeping secrets of her own, and also had good reason for wishing Edwina ill. Two travel tickets and a guidebook to Italy are found in Elizabeths possession. How does she explain that away?Martin proceeds to drop seemingly innocuous but loaded observations into the ears of the three suspects, hoping to provoke doubts and foster mutual suspicion. This works so well that they are soon apparently falling over themselves to incriminate each other. Martin has to try to untangle the stories to come up with a coherent picture of what actually happened, all the while being aware that he is perhaps being manipulated into barking up entirely the wrong tree. ........
