Una tomba aperta... una bara vuota

A black-gloved,razor-wielding killer slashes the throats of people in an eerie mansion.It all has to do with the tragic death of a woman.She was the wife of the main male character.Oliver is convinced that he accidentally caused her lethal fall in their villa while he was drunk.He finds a new wife,but he's incapable of coping with his first wife's death.Moreover the maid and his sister don't seem to accept the new woman in the household.After some time suddenly bodies are piling up slashed by black-gloved killer...Pretty good Spanish/Italian giallo made by Alfonso Balcazar with lovely Teresa Gimpera.The first hour of the movie is relentlessly talky and suitably dull.The gory murders begin during the last thirty minutes.6 out of 10.
