The Shuttered Room

After Susannah Kelton (Carol Lynley) inherits a mill in her small New England hometown, she travels there with her husband, Mike (Gig Young). When they arrive, they are treated coldly by the villagers and are warned against entering the mill by Susannah's gloomy Aunt Agatha (Flora Robson) and shady cousin, Ethan (Oliver Reed). When Susannah ignores the warnings and begins to investigate the mill, she learns that its attic hides a sinister family secret.
