Mystery & Suspense

Inner Sanctum Mysteries.

A creaking door opens and a cheerful host welcomes you somewhere distinctly uncheerful. Inner Sanctum Mysteries pairs macabre stories with grim jokes, creating a horror anthology in which the invitation is almost as memorable as the danger beyond it.

About the programme.

The host stands outside the changing dramas, linking them with an amused taste for the unpleasant. Inside the story, people may face crime, fear or apparently supernatural threats. The contrast between the jokes and the situation is central to the programme's identity.
