He slipped a hand from beneath the Cloak and grasped the snowy and thickly rusted gate, not wishing to open it, but simply to hold some part of the house.
“You’re not going to go inside? It looks unsafe, it might—oh, Harry, look!”
His touch on the gate seemed to have done it. A sign had risen out of the ground in front of them, up through the tangles of nettles and weeds, like some bizarre, fast-growing flower, and in golden letters upon the wood it said:
...
On this spot, on this night of 31 October 1981, Lily and James Potter lost their lives. Their son, Harry, remains the only wizard ever to have survived the Killing Curse. This house, invisible to Muggles, has been left in its ruined state as a monument to the Potters and as a reminder of the violence that tore apart their family.
And all around these neatly lettered words, scribbles had been added by other witches and wizards who had come to see the place where the Boy Who Lived had escaped. Some had merely signed their names in Everlasting Ink; others had carved their initials into the wood, still others had left messages. The most recent of these, shining brightly over sixteen years’ worth of magical graffiti, all said similar things.
...
Good luck, Harry, wherever you are.
If you read this, Harry, we’re all behind you!
Long live Harry Potter.
“They shouldn’t have written on the sign!” said Hermione, indignant.
But Harry beamed at her.
“It’s brilliant. I’m glad they did. I…”
He broke off. A heavily muffled figure was hobbling up the lane toward them, silhouetted by the bright lights in the distant square. Harry thought, though it was hard to judge, that the figure was a woman. She was moving slowly, possibly frightened of slipping on the snowy ground. Her stoop, her stoutness, her shuffling gait all gave an impression of extreme age. They watched in silence as she drew nearer. Harry was waiting to see whether she would turn into any of the cottages she was passing, but he knew instinctively that she would not. At last she came to a halt a few yards from them and simply stood there in the middle of the frozen road, facing them.
He did not need Hermione’s pinch to his arm. There was next to no chance that this woman was a Muggle: She was standing there gazing at a house that ought to have been completely invisible to her, if she was not a witch. Even assuming that she was a witch, however, it was odd behavior to come out on a night this cold, simply to look at an old ruin. By all the rules of normal magic, meanwhile, she ought not to be able to see Hermione and him at all. Nevertheless, Harry had the strangest feeling that she knew that they were there, and also who they were. Just as he had reached this uneasy conclusion, she raised a gloved hand and beckoned.
