“An Engorgement Charm, I suppose?” said Hermione, halfway between disapproval and amusement. “Well, you’ve done a good job on them.”

“That’s what yer little sister said,” said Hagrid, nodding at Ron. “Met her jus’ yesterday.” Hagrid looked sideways at Harry, his beard twitching. “Said she was jus’ lookin’ round the grounds, but I reckon she was hopin’ she might run inter someone else at my house.” He winked at Harry. “If yeh ask me, she wouldn’ say no ter a signed —”

“Oh, shut up,” said Harry. Ron snorted with laughter and the ground was sprayed with slugs.

“Watch it!” Hagrid roared, pulling Ron away from his precious pumpkins.

It was nearly lunchtime and as Harry had only had one bit of treacle fudge since dawn, he was keen to go back to school to eat. They said good-bye to Hagrid and walked back up to the castle, Ron hiccoughing occasionally, but only bringing up two very small slugs.

They had barely set foot in the cool entrance hall when a voice rang out, “There you are, Potter — Weasley.” Professor McGonagall was walking toward them, looking stern. “You will both do your detentions this evening.”

“What’re we doing, Professor?” said Ron, nervously suppressing a burp.

“You will be polishing the silver in the trophy room with Mr. Filch,” said Professor McGonagall. “And no magic, Weasley — elbow grease.”

Ron gulped. Argus Filch, the caretaker, was loathed by every student in the school.

“And you, Potter, will be helping Professor Lockhart answer his fan mail,” said Professor McGonagall.

“Oh n— Professor, can’t I go and do the trophy room, too?” said Harry desperately.

“Certainly not,” said Professor McGonagall, raising her eyebrows. “Professor Lockhart requested you particularly. Eight o’clock sharp, both of you.”

Harry and Ron slouched into the Great Hall in states of deepest gloom, Hermione behind them, wearing a well-you-did-break-school-rules sort of expression. Harry didn’t enjoy his shepherd’s pie as much as he’d thought. Both he and Ron felt they’d got the worse deal.

“Filch’ll have me there all night,” said Ron heavily. “No magic! There must be about a hundred cups in that room. I’m no good at Muggle cleaning.”

“I’d swap anytime,” said Harry hollowly. “I’ve had loads of practice with the Dursleys. Answering Lockhart’s fan mail…he’ll be a nightmare….”

Saturday afternoon seemed to melt away, and in what seemed like no time, it was five minutes to eight, and Harry was dragging his feet along the second-floor corridor to Lockhart’s office. He gritted his teeth and knocked.

The door flew open at once. Lockhart beamed down at him.

“Ah, here’s the scalawag!” he said. “Come in, Harry, come in —”

Shining brightly on the walls by the light of many candles were countless framed photographs of Lockhart. He had even signed a few of them. Another large pile lay on his desk.

“You can address the envelopes!” Lockhart told Harry, as though this was a huge treat.

“This first one’s to Gladys Gudgeon, bless her — huge fan of mine —”

The minutes snailed by. Harry let Lockhart’s voice wash over him, occasionally saying, “Mmm” and “Right” and “Yeah.” Now and then he caught a phrase like, “Fame’s a fickle friend, Harry,” or “Celebrity is as celebrity does, remember that.”

The candles burned lower and lower, making the light dance over the many moving faces of Lockhart watching him. Harry moved his aching hand over what felt like the thousandth envelope, writing out Veronica Smethley’s address. It must be nearly time to leave , Harry thought miserably, please let it be nearly time…

And then he heard something — something quite apart from the spitting of the dying candles and Lockhart’s prattle about his fans.

It was a voice, a voice to chill the bone marrow, a voice of breathtaking, ice-cold venom.

“Come…come to me….Let me rip you….Let me tear you….Let me kill you….”

Harry gave a huge jump and a large lilac blot appeared on Veronica Smethley’s street.

“What ?” he said loudly.

“I know!” said Lockhart. “Six solid months at the top of the best-seller list! Broke all records!”

“No,” said Harry frantically. “That voice!”

“Sorry?” said Lockhart, looking puzzled. “What voice?”

“That — that voice that said — didn’t you hear it?”

Lockhart was looking at Harry in high astonishment.

“What are you talking about, Harry? Perhaps you’re getting a little drowsy? Great Scott — look at the time! We’ve been here nearly four hours! I’d never have believed it — the time’s flown, hasn’t it?”

Harry didn’t answer. He was straining his ears to hear the voice again, but there was no sound now except for Lockhart telling him he mustn’t expect a treat like this every time he got detention. Feeling dazed, Harry left.

It was so late that the Gryffindor common room was almost empty. Harry went straight up to the dormitory. Ron wasn’t back yet. Harry pulled on his pajamas, got into bed, and waited. Half an hour later, Ron arrived, nursing his right arm and bringing a strong smell of polish into the darkened room.

“My muscles have all seized up,” he groaned, sinking on his bed. “Fourteen times he made me buff up that Quidditch cup before he was satisfied. And then I had another slug attack all over a Special Award for Services to the School. Took ages to get the slime off…How was it with Lockhart?”

Keeping his voice low so as not to wake Neville, Dean, and Seamus, Harry told Ron exactly what he had heard.

“And Lockhart said he couldn’t hear it?” said Ron. Harry could see him frowning in the moonlight. “D’you think he was lying? But I don’t get it — even someone invisible would’ve had to open the door.”

“I know,” said Harry, lying back in his four-poster and staring at the canopy above him. “I don’t get it either.”
