The light from the end of her wand caught something in the middle of the room. Pushing past her squeamishness that she was about to be stepping across dried stains of her own blood, Hermione went towards the object. A single silver button lay on the floor. She didn't recognize it as belonging to any set of robes she owned and Antonin didn't care for such showy buttons. His brother, however, had always been the sort to prance around in the finest robes he could afford. Where he got his money was a mystery. She never cared to spend enough time with him in conversation to ask. Not ready to show it to her husband just in case it did take her to the hiding place she was almost certain Aubin was in, she slipped it into her pocket.
