|A carefully plotted Hammer thriller.
Ever since she saw her mother brutally knife her father to death, teenager Janet (Linden) has been of fragile mind. She's worried she too may be psychotic like her momma.
Under the guidance of guardian Henry (Knight) and his assistant Redmond (looking suspiciously like a twin sister for Polly Bergen), the young girl returns to her home estate for a little rest and relaxation.
But soon, Janet is having palpable nightmares...and very real visions of a ghastly woman in white who wanders about the grounds.
What will Janet's fate be? Is there a large butcher knife in her future?
Well acted entry from Hammer is another shocker clearly inspired by PSYCHO.
But as with their superior Scream of Fear (1961), the thoughtful plotting and solid direction here (this time by Freddie Francis) make this worth a watch.
Also known by the (really great) title: Here's the Knife, Dear: Now Use It.
