“Well, you’ve just had a big shock,” said Ron kindly. “What was that supposed to do?”
“It did what I meant it to do!” said Hermione rather crossly. “That was a spell to reveal human presence, and there’s nobody here except us!”
“And old Dusty,” said Ron, glancing at the patch of carpet from which the corpse-figure had risen.
“Let’s go up,” said Hermione with a frightened look at the same spot, and she led the way up the creaking stairs to the drawing room on the first floor.
Hermione waved her wand to ignite the old gas lamps, then, shivering slightly in the drafty room, she perched on the sofa, her arms wrapped tightly around her. Ron crossed to the window and moved the heavy velvet curtains aside an inch.
“Can’t see anyone out there,” he reported. “And you’d think, if Harry still had a Trace on him, they’d have followed us here. I know they can’t get in the house, but—what’s up, Harry?”
Harry had given a cry of pain: His scar had burned against as something flashed across his mind like a bright light on water. He saw a large shadow and felt a fury that was not his own pound through his body, violent and brief as an electric shock.
“What did you see?” Ron asked, advancing on Harry. “Did you see him at my place?”
“No, I just felt anger—he’s really angry—”
“But that could be at the Burrow,” said Ron loudly. “What else? Didn’t you see anything? Was he cursing someone?”
“No, I just felt anger—I couldn’t tell—”
Harry felt badgered, confused, and Hermione did not help as she said in a frightened voice, “Your scar, again? But what’s going on? I thought that connection had closed!”
“It did, for a while,” muttered Harry; his scar was still painful, which made it hard to concentrate. “I—I think it’s started opening again whenever he loses control, that’s how it used to—”
“But then you’ve got to close your mind!” said Hermione shrilly. “Harry, Dumbledore didn’t want you to use that connection, he wanted you to shut it down, that’s why you were supposed to use Occlumency! Otherwise Voldemort can plant false images in your mind, remember—”
“Yeah, I do remember, thanks,” said Harry through gritted teeth; he did not need Hermione to tell him that Voldemort had once used this selfsame connection between them to lead him into a trap, nor that it had resulted in Sirius’s death. He wished that he had not told them what he had seen and felt; it made Voldemort more threatening, as though he were pressing against the window of the room, and still the pain in his scar was building and he fought it: It was like resisting the urge to be sick.
He turned his back on Ron and Hermione, pretending to examine the old tapestry of the Black family tree on the wall. Then Hermione shrieked: Harry drew his wand again and spun around to see a silver Patronus soar through the drawing room window and land upon the floor in front of them, where it solidified into the weasel that spoke with the voice of Ron’s father.
“Family safe, do not reply, we are being watched.”
