This mainly Spanish production is an old-fashioned mystery more concerned with the fear of provincial backwaters than the urban-located terror of most gialli. Although The Murder Mansion establishes its modern Stateside setting with a minor road rage incident on open highways, once the film withdraws onto studio sets shrouded in thick dry ice, it increasingly becomes a spook story. For despite an undemanding plot which could have come from the Old Dark House era or even Scooby-Doo, this is a surprisingly entertaining horror-thriller.
