by Robert Faulcon (Robert Holdstock)
1987 Diamond Books

Suburban England Evil Dead as if written by Nigel Kneale. Paranormal researcher Dan Brady is left for dead after his house is invaded, his wife violated with a golden scepter, and his family kidnapped. Once out of his coma he returns to the house and finds another researcher whose family met the same fate. The two build up the psychic defenses of the house against attacks by astral elementals.

Shades of Quatermass and Stone Tape with the combination of psychical research mixed with ancient folk horror, with the violence ramped up as bodies are ripped apart by unseen forces. Dan Brady is a bit harder edged than your average occult detective type, placing his path of vengeance ahead of uncovering the plot using supernatural forces.
