In the Folds of the Flesh (1970)

Sinopsis

Police are in hot pursuit of a criminal who is evading capture on a speeding motorbike. He takes refuge in an overgrown castle’s grounds and sees a pale woman burying a corpse in a shallow grave. Thirteen years later, after being recaptured and serving his sentence, the man returns to the castle, intent on blackmail — and maybe a few other things.
