This is the most complicated potion I’ve ever seen,’ said Hermione, as they scanned the recipe. ‘Lacewing flies, leeches, fluxweed and knotgrass,’ she murmured, running her finger down the list of ingredients. ‘Well, they’re easy enough, they’re in the student store-cupboard, we can help ourselves. Oooh, look, powdered horn of a Bicorn – don’t know where we’re going to get that ... Shredded skin of a Boomslang – that’ll be tricky, too – and of course a bit of whoever we want to change into.’

Hermione continued as though she hadn’t heard him.
‘We don’t have to worry about that yet, though, because we add those bits last ...’

Hermione shut the book with a snap.
