"Is that so?" Roberts’ tone was certainly unconvinced, though the knife point shifted and Hermione felt another tug at her hair just before hearing the blade slice through. "We shall see." Releasing her, he walked to the door and opened it, calling out.  So there was at least one other accomplice, Hermione thought as Roberts passed a handful of her hair out.  And they clearly have far more polyjuice than they have any right to  ,  though that would certainly explain the apothecary break-in...  But the Aurory, why destroy the locker rooms...  She frowned for a moment.   That must have been where they had found Harry’s hair. Not to mention the hair of Merlin knows how many other Aurors...  not that she could do much with this information while shackled to a bloody wall... Her eyes flicked to Severus and she saw a slight frown at the corner of his mouth before his eyes met hers and his expression shifted to something more pensive. She wished, as she had sporadically over the years, that she had his talent for legilimency. The ability to hold a silent conversation between them would certainly come in handy right now.
