I woke with my mind buzzing and my stomach churning. It was my first ever Hogsmeade trip! Before I knew it, I was shaking Helda’s waking body, pulling on casual, out-of-school clothes, and running down the moving staircases to the Great Hall for a rushed breakfast of porridge.

An hour later, Helda and I were strolling through the quiet streets of Hogsmeade. ‘What did you say we were looking for again?’ I asked.

‘I’d like to show you Madam Puddifoot’s,’ she said. ‘It’s really nice, you’ll love it- especially their teacakes, they’re so good! And anyway, there’s somebody who wants to meet me there.’

‘Who?’

‘I have no idea. Some crazy teacher who thinks rather stupidly that I’m good at their subject.’ She took out a piece of parchment from her pocket. I read it aloud, my curiosity growing every second.

'Dear Miss Helda,
I wish to congratulate you on your success in my recent lessons. Would it be possible to meet at Madam Puddifoot’s Tea Rooms on the soonest Hogsmeade trip? Twelve noon is the best time for me.
From, ???'

‘Seriously?’ I said, shaking my head. ‘You don’t know who's handwriting that is, after seeing it written on a chalkboard every week the last three years? After three years of having sourly marked work turned in with horrid comments and this same writing all over it?’

‘No, who?’ asked Helda.

‘Only Awful Artemus!’
