The Girl in Black Stockings.

Residents at a posh Utah hotel become suspects when a girl is found murdered during a pool party. Local sheriff Jess Holmes takes charge of the investigation and must discover who among the terrified guests and staff -- including bodacious vixen Harriet Ames, the hotel's bitter, crippled proprietor, visiting lawyer David Hewson and his secretary, Beth -- is the culprit, even as murders continue to take place.
