I read it! I enjoyed it, yet I must take 'umbrage' at the imposition of a new headteacher!

The placenames continue to enchant! so far we've had;
1, How do you fit another street into London's crowded map ?
2, When and where do black wizards shop ?
3, How would you best describe Sirius Black's ancestral pile ?

1, Diagonally               (Diagon Alley)
2, Nocturnally             (Knockturn Alley)
3, a Grim Old Place    (Grimmauld Place)
