Julian Fitzwarren

Julian Fitzwarren, also known as Julian Moss, is the husband of Phyllis Fitzwarren and cousin of Rose Fitzwarren. He had Rose placed in an insane asylum so he would be able to receive her inheritance, but when that didn't work out, he tracked down Rose at Rookwood School on their trip and, with the somewhat-unwilling help of his wife, cast doubt upon Rose and threatened to kill her unless she gave him the key to the safe where her parents' will was kept. He is first mentioned in The Whispers in the Walls, and first appears in The Lights Under the Lake.
