Back at Hogwarts for third year!
Lyrics at the beginning of the chapter are the opening lines of 'Width of a Circle' from David Bowie's 'Man Who Sold the World' album.
Lyrics:
In the corner of the morning in the past
I would sit and blame the master first and last
All the roads were straight and narrow
And the prayers were small and yellow
And the rumour spread that I was aging fast
Then I ran across a monster who was sleeping
By a tree
And I looked and frowned and the monster was me
