@cheezncrackers thanks for the summary.
I have listened to some Youtube videos. It appears the (friendly) old lady ghost was Marion Holborn, who had lived in the house a decade before. A local historian helped discover this via some photos, from which Liz recognised her face. Marion herself had been visited by some strange happenings - radiators being pulled off walls.
What was the 7 foot shadowy figure with a bird's head (mask?) - an ancient Celtic spirit summoned to scare enemies, or something to do with the necklace from the Egypt trip (Horus)? Last seen on a nearby hilltop staring at the farm.
Previous owner had one occurrence, where a spinning wheel set off going in her bedroom. She got up and wedged it with some paper. She said to Liz 'there are things that happen that you can choose to see or you can choose not to see. I chose not to see.'
More interesting stuff about the horse picture. He couldn't paint the back leg right - the horse died of an infection in that leg. It looked exactly like the leg in the painting. Horse buried in the field as he had painted it.
Discrepancies about the Egyptian amulet - did they find it on holiday or did it just appear at Liz's mums (Bill smashes it with a hammer after it gives him a massive static charge)?
House as a passing through space for spirits (neutral, just lost)
57 minutes in - the last visit of Eddie Burks and Maurice Grosse.
After March 1996, nothing. 25 years of peaceful life. Lands managed for wildlife and has won awards for stewardship. Rare butterflies in residence.
- in this film from a year ago the house seems abandoned.
So do people still live here or not?
