Mystique straightened up her spell books, in their bookcases. Today was quite windy, and the door kept blowing open, making the bell above it ring. 'Colloportus' she said, but making the spell lock for an only temporary time, in case any customers were thinking of buying a book, or individual spell.
She went over to the corner of her shop, gripped her wand and started doing enchantments over the cupboards, locking them, until she desired an item from within. The ministry had been looking for people like her, the ministry had been looking for death eaters, and her store which looked happy form the outside was already attracting many customers.
On a blackboard at the front of the store it said,
Dark Magic for the Young 9 G's
Beastly Books for Beginners 11 G's
Tedious Book of Tricks 14 G's
Ghastly Spells for The Gallant 13 G's
Jokers book of Jokes 4 G's
Side-effect's for Skeeves 7 G's
A counter-curse Special Edition 17 G's
She finished her enchantments when the bell rang once more, "Oh would you shut up," she said screaming at the bell. She turned around and peered into the face of a woman.
