Jerry Masterfield is a character in
Power of Three.
He is a
Giant, and according to the laws of the Giants owns a large part of the
Moor, including the bit with
Garholt on it.
He lives at Moor Farm with his son,
Gerald, and his sister, Gerald's
Aunt Mary. His wife died in childbirth.
He studied at Oxford, where he was a close friend of George Claybury, who was Best Man at his wedding, but their friendship later soured.
This, like the death of Mrs Masterfield, is connected to the curse on the Moor.
