Carver nodded, listening along. "There are three witches, though. If any of them see you flying, they're likely to come after you. And if you 'borrow' all of them, they'll figure something's up and tell Jack before you have a chance to set it off."

She grinned. "On the other hand, if two of their brooms [i]mysteriously[/i] end up glued to random walls in the shop, they're more likely to assume that the third one is glued to something somewhere as well, and that [i]that[/i] was the extent of the prank. Make them a bit annoyed at you, but less suspicious that there might be [i]other[/i] things we're up to."

She rubbed her hands gleefully. "If Barrel can 'relieve' the witches of their stock of glue dissolvent, I can get an [i]early[/i] batch of Eternal Glory Juice into the the Doctor's brain compartment, to make sure he can't make any more."
