fail, Kronos accidentally pierces Marcus's chest with a cross of steel that Marcus had been wearing round his neck. Having thus determined the vampire's weakness, Kronos and Grost obtain an iron cross from a cemetery. They are accosted by angry villagers, who believe that they murdered Marcus. Grost forges the cross into a sword, while Kronos conducts a knightly vigil. After seeing the Durward carriage flee the scene of a vampire attack, Kronos suspects Sara as the vampire. Carla seeks refuge at Durward Manor to distract the household while Kronos sneaks inside. The "bedridden" Lady Durward reveals herself as the newly-youthful vampire, and she hypnotises Carla and the Durward siblings. Lady Durward has raised her husband Hagen (William Hobbs) from the grave. She offers the mesmerised Carla to her husband, but Kronos erupts from hiding. Kronos uses the new sword's mirrored blade to turn Lady Durward's hypnotic gaze against her. He kills Lord Durward in a duel, and then destroys Lady Durward. The next day, Kronos bids Carla goodbye, before he and Grost ride on to new adventures.

In later years, the film became a cult classic, largely because of its unusual mix of supernatural horror and swashbuckling action. It was supposed to launch a series of new Hammer film productions but, in the 1970s, the studio developed financial issues and closed down.
