Did they buy the house for Jeremy or was it a farm cottage they already owned?
According to JM's statement:
In April 1984 Jeremy moved into 9 Head Street, Goldhanger. This house was purchased for him by his parents. We continued our friendship and in Easter 1984 I spent all the School holiday at Jeremy's house. I decorated the house whilst he was working on the farm.
Just because it's in JM's statement I know doesn't make it the truth.
