Harry could tell that Uncle Vernon was thinking it over, even if his teeth were bared and a vein was throbbing in his temple.

"Right," he snapped finally. "I shall monitor your behavior carefully during Marge's visit. If, at the end of it, you've toed the line and kept to the story, I'll sign your ruddy form."

He wheeled around, pulled open the front door, and slammed it so hard that one of the little panes of glass at the top fell out.

Harry didn't return to the kitchen. He went back upstairs to his bedroom. If he was going to act like a real Muggle, he'd better start now. Slowly and sadly he gathered up all his presents and his birthday cards and hid them under the loose floorboard with his homework. Then he went to Hedwig's cage. Errol seemed to have recovered; he and Hedwig were both asleep, heads under their wings. Harry sighed, then poked them both awake.

"Hedwig," he said gloomily, "you're going to have to clear off for a week. Go with Errol. Ron'll look after you. I'll write him a note, explaining. And don't look at me like that" - Hedwig's large amber eyes were reproachful - "it's not my fault. It's the only way I'll be allowed to visit Hogsmeade with Ron and Hermione."

Ten minutes later, Errol and Hedwig (who had a note to Ron bound to her leg) soared out of the window and out of sight. Harry, now feeling thoroughly miserable, put the empty cage away inside the wardrobe.

But Harry didn't have long to brood. In next to no time, Aunt Petunia was shrieking up the stairs for Harry to come down and get ready to welcome their guest.

"Do something about your hair!" Aunt Petunia snapped as he reached the hall.

Harry couldn't see the point of trying to make his hair lie flat. Aunt Marge loved criticizing him, so the untidier he looked, the happier she would be.

All too soon, there was a crunch of gravel outside as Uncle Vernon's car pulled back into the driveway, then the clunk of the car doors and footsteps on the garden path.

"Get the door!" Aunt Petunia hissed at Harry.

A feeling of great gloom in his stomach, Harry pulled the door open.

On the threshold stood Aunt Marge. She was very like Uncle Vernon: large, beefy, and purple-faced, she even had a mustache, though not as bushy as his. In one hand she held an enormous suitcase, and tucked under the other was an old and evil-tempered bulldog.

"Where's my Dudders?" roared Aunt Marge. "Where's my neffy- poo?"

Dudley came waddling down the hall, his blond hair plastered flat to his fat head, a bow tie just visible under his many chins. Aunt Marge thrust the suitcase into Harry's stomach, knocking the wind out of him, seized Dudley in a tight one-armed hug, and planted a large kiss on his cheek.

Harry knew perfectly well that Dudley only put up with Aunt Marge's hugs because he was well paid for it, and sure enough, when they broke apart, Dudley had a crisp twenty-pound note clutched in his fat fist.

"Petunia!" shouted Aunt Marge, striding past Harry as though he was a hat stand. Aunt Marge and Aunt Petunia kissed, or rather, Aunt Marge bumped her large jaw against Aunt Petunia's bony cheekbone.

Uncle Vernon now came in, smiling jovially as he shut the door.

"Tea, Marge?" he said. "And what will Ripper take?"

"Ripper can have some tea out of my saucer," said Aunt Marge as they all proceeded into the kitchen, leaving Harry alone in the hall with the suitcase. But Harry wasn't complaining; any excuse not to be with Aunt Marge was fine by him, so he began to heave the case upstairs into the spare bedroom, taking as long as he could.

By the time he got back to the kitchen, Aunt Marge had been supplied with tea and fruitcake, and Ripper was lapping noisily in the corner. Harry saw Aunt Petunia wince slightly as specks of tea and drool flecked her clean floor. Aunt Petunia hated animals.
