E25: Ruthin Castle

About 20 miles from the Irish sea in Wales lies Ruthin Castle. For centuries, people have reported seeing spirits of those who have perished there. Lady Grey looking for her axe. A soldier wandering the halls. A young girl with golden ringlets walking and giggling on Upper Clwyd Street. Who were these ghosts in life, how did they die, and why are they haunting Ruthin Castle?
