“That’s when they decided there was only one way to stop me, I suppose, and they went for Gran.”
“They what?” said Harry, Ron, and Hermione together.
“Yeah,” said Neville, panting a little now, because the passage was climbing so steeply, “well, you can see their thinking. It had worked really well, kidnapping kids to force their relatives to behave, I s’pose it was only a matter of time before they did it the other way around. Thing was,” he faced them, and Harry was astonished to see that he was grinning, “they bit off a bit more than they could chew with Gran. Little old witch living alone, they probably thought they didn’t need to send anyone particularly powerful. Anyway,” Neville laughed, “Dawlish is still in St Mungo’s and Gran’s on the run. She sent me a letter,” he clapped a hand to the breast pocket of his robes, “telling me she was proud of me, that I’m my parents’ son, and to keep it up.”
