Cave of the Living Dead

The police cannot solve the mystery of seven murders which have alarmed the inhabitants of a small village. They call in Inspector Doren of Interpol. The only clue the local constable can give his young and famous colleague is the fact that, each time a murder was committed , the electric lights in the whole neighborhood went out. The villagers believe that the murders of the young girls are linked to the vague shadows in the caves under the local castle and to the mysterious curse of the green eyes. They distrust the Inspector and offer no assistance when still another murder takes place at the village inn--in the room next to the detective's--and the body disappears. Doren moves to the castle, where Professor Adelsberg is carrying out some scientific studies. There he meets the professor's pretty assistant, Karin. She is marked as the next victim, but the Inspector is able to thwart the murderer. As Doren closes in, he barely escapes with his own life, but he manages to discover the secret of the caves of the living dead and to unmask the culprit.
