Nine Coaches Waiting (1958)

Linda Martin, an English woman is hired to be a governess for a young French boy. But a strange terror coiled in the shadows behind the brooding elegance of the huge Château Valmy. It lay there like some dark and twisted thing -- waiting, watching, ready to strike. Was it only chance encounter than had brought the lovely governess to the château? Or was it something planned? She only knew something was wrong and that she was afraid. She is unaware of the danger she faces or who to trust in order to protect the young heir. Now she could not even trust the man she loved. For Raoul Valmy was one of them -- linked by blood and name to the dark secrets of the Valmy past.
