Sorry posting in AIBU for traffic.
My son read a book to me when he was about 9/10 that was really good but it was 5/6 years ago and I can't remember the title. I've tried googling but can't find it.
99% sure it's set in the UK. A boy (age 10ish) moves into a manor house/mansion with his younger sister (I think) and his father. They move in because his dad is going to do the house up to sell it or because he's been employed to do it up.
Creepy things happen but I can't remember what exactly. One wing of the house is completely boarded up and they can't get in. Around the house are paintings of people that have lived in the house, the house and the large ground and I think these change as when someone dies they are magically added to the picture.
The Lord of the manor type person who previously lived in the house liked to hunt. I think he hunted visitors to the house and chased them round the grounds and killed them.
Somehow the boy or his sister gets into the boarded up section of the house and gets trapped in a small room.
I can't remember much else. Except maybe a dog appearing in one of the portraits.
Any ideas???
