La última señora Anderson

A wealthy Art Anderson is happily married to his fourth wife when, one day, he finds her dead body floating in their pool. Suspicions immediately fall on him, given that his previous three wives all died under similar circumstances, and he is the beneficiary of their life insurance policies. Nevertheless, nothing is what it seems. This Spanish-style giallo filmed by the director of Horror Express (1972) brings together two stars in their respective countries, Carroll Baker and José Luis Lopez Vazquez.
