Darting forwards like a ghost, he came up behind Boot just as he was swallowing the water. He turned, eyes wide in surprise, as Neville balled up his fist and drove it fiercely into Boot’s solar plexus. A rib cracked, Neville heard that, but he kept his fist embedded in the fleshy stomach muscle, using his other strong hand to keep Boot steady and upright. He coughed, spluttered out his water, but then froze as Neville reached down and drew his wand, jabbing it into the base of Boot’s spine.
