Just as they'd all suspected, Hermione wasn't in the Great Hall. Was she still in Dumbledore's office, though? Sirius knew that he shouldn't take out the Map in public. It was their trump card, after all, but he needed to know where Hermione was. All he had to do was play it cool, as if it were just any old parchment. He reached into his pocket and laid the Map out on the table, keeping the sides folded up so no one else could see. "I solemnly swear I am up to no good," he mouthed, surreptitiously poking the Map with his wand.
