My Name Change

HoHo, What a Card, You obviously dont know me Prudence, for in the Real world, I am known as Bernard Manning, Man of the North extraordinaire.

As to my name change, well I was fed up with my previous occupation, it was too limited for me, Now I am thief, and your worst nightmare Prudence.

For anyone who really wants to know who I was, It wouldn't take a genius to work out who I used to be.
