The Ghost (1963) [Blu-ray]

In 1963, Riccardo Freda directed one of Italy's landmark horror thrillers: In turn-of-the-century Scotland, a young wife (Barbara Steele) conspires with her lover (Peter Baldwin) to murder her wealthy, paralyzed surgeon husband. But when the dead spouse's spirit returns to haunt the couple, it will unleash a nightmare of spectral terror, sudden violence and depraved vengeance.
