One Man and His Dog

Jack Rainor was not your usual postman having once been if not the most powerful wizard in the world then by general acclamation the most dangerous; but that was ten years ago. Now he lives a quiet life in the North of England; a quiet, normal, mundane sort of a life.
No one wants him back meddling in long buried affairs.
Not his daughter who forced him to exile in the first place and is now one of the most powerful wizards in the Council of the Wise.
Not the Head of that self-same Council.
Not the reavers and Vampyrs he butchered in such numbers.
Nobody wants him back...but plenty of people appear to want him dead. Which could be a problem for them because the last person who you should fail to kill is the Lord of All Murder.
