And Soon The Darkness (1970)

Two young British nurses (Pamela Franklin, Michele Dotrice) are on a biking holiday in France. The two women argue and one (Franklin) leaves the other (Dotrice) to continue the biking alone. But when she feels guilty for abandoning her companion, Franklin returns to the spot where she left her friend only to find she's not there. When she learns that a young English girl was murdered in the same area the year before, the nurse suspects the worst.  Directed by Robert Fuest (THE ABOMINABLE DR. PHIBES), the film did a modest business at the box office but was dismissed by the critics who found the film unpleasant. Its reputation has grown in the ensuing years and justifiably so I think. It's a taut little thriller infused with a generous amount of suspense by director Fuest. If the identity of the murderer is a bit too obvious, the sense of dread created throughout keeps you on the edge and the movie's ending is wonderfully executed. With Sandor Eles, John Netttleton, Jean Carmet and Clare Kelly.
